Experimental Chromium Web Platform Features
Experimental web platform features are not yet part of the official web platform specifications and are marked as “experimental” in Chromium.
Polypane ships with these features (and more) enabled by default. Other Chromium browsers let you enable these on a “flags” settings page.
Chromium 139 current
▹ Audio Context Playout Stats
AudioContextPlayoutStatschromestatus.comThe AudioContext.playoutStats API allows an application to measure the quality and latency of audio playout using WebAudio.
▹ Blocking Focus Without User Activation
BlockingFocusWithoutUserActivationchromestatus.comA permissions policy to restrict the use of programmatic focus, when not triggered by a user activation. The proposed policy provides a way to control access to the focus API without user activation. The immediate use case would be restricting all sandboxed frames. Focus API, in this context refers to focus management API and autofocus.
▹ Boundary Event Dispatch Tracks Node Removal
BoundaryEventDispatchTracksNodeRemovalchromestatus.comAfter an event target gets removed from the DOM, the logical target of the pointer as implied by the Pointer and Mouse boundary events (i.e. over, out, enter and leave events) should be the nearest ancestor still attached to the DOM. PEWG has recently reached consensus on this behavior, see https://github.com/web-platform-tests/interop/issues/380. Chrome has been keeping track of a node even after it gets removed from DOM. As a result, if the pointer moves to a new node B after the hit-test node A is removed from DOM, the boundary event sequence (pointerover, pointerout, pointerenter, pointerleave events and the corresponding mouse events) used to imply a pointer movement from A to B. As per the new consensus, the event sequence should imply a pointer movement from the "parent of A" to B.
▹ Canvas Text Ng
CanvasTextNgchromestatus.comThis is not a web-exposed change. The implementation of CanvasRenderingContext2D's measureText(), fillText(), and strokeText() has a drastic change. This might affect performance, so we'd like to run an origin trial so canvas-heavy applications can try out the new implementation.
▹ Capability Delegation Display Capture Request
CapabilityDelegationDisplayCaptureRequestchromestatus.comThis feature is based on the general delegation mechanism (https://chromestatus.com/feature/5708770829139968) shipped on M100. Display-Capture Capability Delegation allows a Window to transfer the ability to call navigator.mediaDevices.getDisplayMedia() to another Window it trusts after relinquishing the transient user activation at the sender Window.
▹ Container Timing
ContainerTimingchromestatus.comThe Container Timing API enables monitoring when annotated sections of the DOM are displayed on screen and have finished their initial paint. A developer will have the ability to mark subsections of the DOM with the containertiming attribute (similar to elementtiming for the Element Timing API) and receive performance entries when that section has been painted for the first time. This API will allow developers to measure the timing of various components in their pages.
▹ Context Menu
ContextMenuchromestatus.comChange “click”, “contextmenu”, “auxclick” events to PointerEvent (instead of MouseEvent) to let developers: distinguish between mouse, pen and individual fingers in a multitouch interaction through pointerType and pointerId attributes, and utilize fractional event coordinates for high precision use cases.
▹ Controlled Frame
ControlledFramechromestatus.comAdds a Controlled Frame API available only to Isolated Web Apps (IWAs). This work adds a new Controlled Frame API which is only available to Isolated Web Apps (IWAs). Like similarly-named APIs on other platforms, Controlled Frame allows embedding all content, even third party content that can't be embedded in <iframe>. Controlled Frame also allows controlling embedded content with a collection of API methods and events. For more info on Isolated Web Apps, see the IWA explainer: https://github.com/WICG/isolated-web-apps/blob/main/README.md
▹ CSS Alt Counter
CSSAltCounterchromestatus.comcounter() and counters() in alt text of 'content' property is useful to provide more meaningful information to e.g. pseudo-elements to improve their accessibility.
▹ CSS Border Shape
CSSBorderShapechromestatus.comCSS border-shape enables creating non-rectangular borders, with any arbitrary shape (polygon, circle, shape(), etc). Though border-shape accepts the same shapes as clip-path, it is fundamentally different: border-shape defines the shape of the border, decorates it, and clips only the inside. border-shape has two variants: one variant that strokes a shape, and another variant that fills between two shapes.
▹ CSS Caret Animation
CSSCaretAnimationchromestatus.comChromium supports animation of the caret-color property, but when animated the default blinking behavior of the caret interferes with the animation. For instance, see the example at https://drafts.csswg.org/css-ui/#caret-animation where an animation from blue to red and back is rendered as a blinking cursor that is randomly blue or red. The CSS caret-animation property has two possible values: auto and manual, where auto means browser default (blinking) and manual means the page author is controlling the caret animation. In addition, via a user stylesheet, it allows users who are disturbed by or have adverse reactions to blinking or flashing visuals to disable the blinking.
▹ CSS Fallback Container Queries
CSSFallbackContainerQuerieschromestatus.comIntroduce @container anchored(fallback) to style descendants of anchor positioned elements based on which of position-try-fallbacks is applied. Such queries can be used to e.g. style an anchored element's tether, its animations, etc. based on how the anchor and the anchored element are positioned relative to each other. Example: #anchored { position-try-options: flip-block; container-type: anchored; } @container anchored(fallback: flip-block) { #anchored { --arrow-rotation: 180deg; } }
▹ CSS Gap Decoration
CSSGapDecorationchromestatus.comCSS Gap Decorations enables styling of gaps in container layouts like Grid and Flexbox, similar to ‘column-rule’ in multicol layout. This feature is highly requested by web authors who must use hacks to style the gaps in Grid and Flexbox layouts today.
▹ CSS Safe Printable Inset
CSSSafePrintableInsetchromestatus.comPrinters usually have a small area at each of the four edges of a sheet of paper that they are not capable of marking reliably, usually due to the printer’s paper handling mechanism. The default page margins are expected to be bigger than these areas, but if authors set margins on their own, and even want to add @page margin boxes (e.g. for custom headers and footers), they need a way of telling where it's safe to print and not. The CSS environment variable env(safe-printable-inset) can be used to obtain this information. It will be the inset of the largest unprintable area. Although some printers don't have the same unprintable area inset along each of the four paper edges, printers may rotate the print output at their own discretion. The user agent cannot make assumptions about which edge (will it be the long or short edge?) is going to be fed first into the printer. Therefore, only one value can be reliably provided here: The larger of these four values.
▹ CSS Scroll Target Group
CSSScrollTargetGroupchromestatus.comThe scroll-target-group property specifies whether the element is a scroll marker group container. 'none': The element does not establish a scroll marker group container. 'auto': The element establishes a scroll marker group container forming a scroll marker group containing all of the scroll marker elements for which this is the nearest ancestor scroll marker group container. Establishing scroll marker group container allows for anchor HTML elements with fragment identifier that are inside such container to be HTML equivalent of ::scroll-marker pseudo elements. The anchor element whose scroll target (the element its fragment identifier is pointing to) is currently in view to be styled via :target-current pseudo class.
▹ CSS Text Auto Space
CSSTextAutoSpacechromestatus.comInserts small spacings to match the established typographic rules automatically. The spec currently defines one rule for Han ideographic characters and one for French. The initial implementation focuses on the Han ideographic characters rule. Text written in Han ideographic writing systems often mixes multiple scripts, usually the Han ideographic scripts, Latin scripts, and ASCII digits. Small spacings when switching from and to non-Han ideographic scripts often help the readability. This property lets browsers insert such spacings automatically. This property has several values, including values for other writing systems. The initial implementation supports `normal` and `no-autospace`. The initial value is set to `no-autospace` to start conservatively and be more careful for the site compatibilities. Authors can add `text-autospace: normal` to enable the feature.
▹ CSS Typed Arithmetic
CSSTypedArithmeticchromestatus.comTyped arithmetic allows to write expressions in CSS such a calc(10em / 1px) or calc(20% / 0.5em * 1px) which is useful for e.g. typography, as it allows to convert typed value into an untyped one and reuse it for number accepting properties or futher multiply the unitless value by some other type to e.g. cast from pixels to degrees.
▹ CSS View Transition Auto Name
CSSViewTransitionAutoNamechromestatus.comContact emails vmpstr@chromium.org, nrosenthal@chromium.org Explainer None Specification https://drafts.csswg.org/css-view-transitions-2/#auto-vt-name Summary 'auto' uses the element's id attribute to generate a unique match for view transition cases. In absence of the id, it generates a unique id based on the element's identity and remains the same for this element. This is used in Single Page App or Multi Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ Device Attributes Permission Policy
DeviceAttributesPermissionPolicychromestatus.comThe new Permissions Policy enables restricting access to the Device Attributes API, which is available only for policy-installed kiosk web apps and policy-installed Isolated Web Apps, both only on managed ChromeOS devices. Additionally, the feature is controlled by content settings. 2 new policies are introduced: DeviceAttributesBlockedForOrigins and DefaultDeviceAttributesSetting, to complement the introduced earlier DeviceAttributesAllowedForOrigins. The feature is enabled by default for the supported scenarios described above.
▹ Device Orientation Request Permission
DeviceOrientationRequestPermissionchromestatus.comAllows developers to ask for permission to use the Device Orientation and Device Motion APIs. Access to these APIs is currently granted by default, and these new functions are part of the long-term plan to require requesting permission before using window.ondevicemotion and window.ondeviceorientation.
▹ Dialog New Focus Behavior
DialogNewFocusBehaviorchromestatus.comSome changes are being made to which element is selected to get focus when a dialog element is opened: 1. Make the dialog focusing steps look at keyboard focusable elements instead of any focusable element. 2. Make the dialog element itself get focus if it has the autofocus attribute set. 3. Make the dialog element itself get focus as a fallback instead of focus being "reset" to the body element.
▹ Document Isolation Policy
DocumentIsolationPolicychromestatus.comDocument-Isolation-Policy allows a document to enable crossOriginIsolation for itself, without having to deploy COOP or COEP, and regardless of the crossOriginIsolation status of the page. The policy is backed by process isolation. Additionally, the document non-CORS cross-origin subresources will either be loaded without credentials or will need to have a CORP header.
▹ Extended Text Metrics
ExtendedTextMetricschromestatus.comExpand the TextMetrics Canvas API to support selection rectangles, bounding box queries, and grapheme cluster-based operations. This new functionality should enable complex text editing applications with accurate selection, caret positioning, and hit testing. Additionally, cluster-based rendering facilitates sophisticated text effects such as independent character animations and styling.
▹ Face Detector
FaceDetectorchromestatus.comThe Face Detection API is a subset of the Shape Detection API which provides the ability to detect human faces and facial landmarks in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Fetch Retry
FetchRetrychromestatus.comAllow web developers to indicate that a fetch() request should be retried, to have a greater guarantee on it being reliably sent, even if network is flaky. This is especially important for keepalive fetches, where the request might outlive the document, which can no longer watch for its failure and do manual retry. We intend to only support this for keepalive fetches for now because of implementation simplicity, and also the fact that all the use cases would benefit from being keepalive first.
▹ File System Access API Experimental
FileSystemAccessAPIExperimentalchromestatus.comCurrently, the File System Access API does not support an efficient way to move or rename files or directories. This requires creating a new file/directory, copying over data (recursively, in the case of a directory), and removing the original. This process is slow, error prone (e.g. disk full), and can require re-uploading files in some cases. See https://github.com/WICG/file-system-access/pull/317
▹ Focusgroup
Focusgroupchromestatus.comThe Focusgroup feature will facilitate keyboard focus navigation using the keyboard arrow keys among a set of focusable elements.
▹ Font Feature Settings Descriptor
FontFeatureSettingsDescriptorchromestatus.comAs CSS allows fine control over font features using 'font-feature-settings' at the element level, Chromium-based browsers currently lack support for these properties within '@font-face' declarations. This feature supports the string-based syntax for font-feature-settings as defined in CSS Fonts Level 4. Invalid or unrecognized feature tags will be ignored per specification. No binary or non-standard forms are supported. As OpenType fonts become more widely adopted, this enhancement will improve typographic control, reduce redundancy, and support a more scalable, modern approach to web design.
▹ Gamepad Multitouch
GamepadMultitouchchromestatus.comExtend the Gamepad API to support multitouch surfaces (touchpads). Providing a touchpad API eases application implementation and provides greater functionality browser interoperability.
▹ Heading Offset
HeadingOffsetchromestatus.comA system for creating structured headings within a document. The `headingoffset=` attribute can be added to elements that influences the child `h1`-`h6` elements' heading levels, for example a `headingoffset=1` will mean all `h1` elements will have an effective heading level of 2, and so on. In addition the `:heading` pseudo class will select all headings (tags of `h1` to `h6`) and the `:heading(N)` pseudo class will select headings with an _effective_ level of `N`. This allows for documents with different heading structures (for example user generated content) to be combined to create a well defined heading structure without significantly altering the underlying documents.
▹ HTML Element Scroll Parent
HTMLElementScrollParentchromestatus.comThe scrollParent attribute on HTMLElement returns the nearest scroll container containing block of the element's. In particular this is the nearest scroll container whose scroll offset affects the element's position. This can be useful to jump to elements to scroll or to elements on which to add scroll listeners to detect when the user scrolls.
▹ Indexed Db Get All Records
IndexedDbGetAllRecordschromestatus.comThis feature adds the getAllRecords() API to IndexedDB's IDBObjectStore and IDBIndex. It also adds a direction parameter to getAll() and getAllKeys(). This functionality enables certain read patterns to be significantly faster when compared to the existing alternative of iteration with cursors. One key workload from a Microsoft property showed a 350ms improvement. getAllRecords() effectively combines getAllKeys() and getAll() by enumerating both primary keys and values at the same time. For an IDBIndex, getAllRecords() also provides the record's index key in addition to the primary key and value. getAllRecords() can optionally return records in either ascending or descending order. This option is also back-ported to the existing operations getAll() and getAllKeys().
▹ Inverted Colors
InvertedColorschromestatus.comAdds the `inverted-colors` media feature, an indication that the user agent or underlying operating system has forcibly inverted all colors, not a request to do so. This is sometimes provided as a simple accessibility feature, allowing users to switch between light-on-dark and dark-on-light text. Valid options are 'inverted' or 'none'.
▹ Media Capture Background Blur
MediaCaptureBackgroundBlurchromestatus.comThe Background Blur API allows web developers to use the native platform's API for camera background segmentation. As Background Blur has become one of the most used features on video conferencing apps like Teams, Meet, Zoom, and Webex, we want web apps to leverage the same platform APIs without completely relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud based solutions.
▹ Media Capture Voice Isolation
MediaCaptureVoiceIsolationchromestatus.comThis is about adding support in Chrome for the VoiceIsolation getUserMedia constraint (https://w3c.github.io/mediacapture-extensions/#voiceisolation-constraint). The constraint only takes effect on platforms where there is low-level support for voice-isolation style denoising. Currently this is limited to a selected number of ChromeOS devices, but further platforms will be added.
▹ Media Source Extensions For Web Codecs
MediaSourceExtensionsForWebCodecschromestatus.comExtends the Media Source Extensions API (MSE) to enable buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.
▹ Multicol Column Wrapping
MulticolColumnWrappingchromestatus.comAdd support for the `column-wrap` and `column-height` CSS properties, from multicol Level 2. https://drafts.csswg.org/css-multicol-2/#cwr https://drafts.csswg.org/css-multicol-2/#ch This allows for vertical column layout, or even 2D column layout. Columns can have an explicit constrained height, apart from being derived from the content-box height of the multicol container, and wrap to a new row of columns when all columns have been filled for one row, rather than creating overflowing columns in the inline direction.
▹ Navigate Event Commit Behavior
NavigateEventCommitBehaviorchromestatus.comNormally, when navigateEvent.intercept() is called, the intercepted navigation commits (and therefore the URL updates) as soon as the NavigateEvent finishes dispatch. Adding a `precommitHandler` option to navigateEvent.intercept(), similar to `handler`, would defer the commit until that handler (and all other precommit handlers) are resolved, also allowing the handler to change the navigation's URL, info, status, and history handling behavior (push/replace).
▹ Navigation Id
NavigationIdchromestatus.comThis adds a Performance Timeline entry type, "back-forward-cache-restoration", which is emitted every time that a page is retrieved from the back-forward cache, and a field on all performance timeline entries, "navigationId", which can be used to tie performance events to the most recent navigation-like event. This allows developers to more easily use the performance APIs to compare the user experience of an SPA or a bfcache-eligible page with that of a traditional multi-page experience.
▹ Nested View Transition
NestedViewTransitionchromestatus.comAllow view-transitions to generate a nested pseudo-element tree rather than a flat one. This allows the view transition to appear more in line with its original elements and visual intent, as it enables clipping, nested 3D transforms, and proper application of effects like opacity, masking and filters.
▹ Paint Timing Mixin
PaintTimingMixinchromestatus.comExpose "paintTime" and "presentationTime" in event timing, element timing, LCP, long animation frames, paint timing. "paintTime" means the time when the rendering phase ended and the browser started the paint phase. "presentationTime" means the time when the "pixels reached the screen", which is somewhat implementation-defined
▹ Payment App
PaymentAppchromestatus.comThe API helps to develop new payment apps in web standard ways (e.g. service worker). If using them, payment app providers can provide simplified payment methods and user experiences.
▹ Payment Link Detection
PaymentLinkDetectionchromestatus.comAdds support for <link rel="facilitated-payment" href="..."> as a hint that the browser should notify registered payment clients about a pending push payment.
▹ Payment Request
PaymentRequestchromestatus.comTo help developers reduce friction in Payment Request flows, we are removing the user activation requirement. Spam and clickjacking mitigations are put in place to mitigate security and privacy risks with this change.
▹ Performance Navigation Timing Confidence
PerformanceNavigationTimingConfidencechromestatus.comWeb applications may suffer from bimodal distribution in page load performance, due to factors outside of the web application’s control. For example: * When a user agent first launches (a "cold start" scenario), it must perform many expensive initialization tasks that compete for resources on the system. * Browser extensions can affect the performance of a website. For instance, some extensions run additional code on every page you visit, which can increase CPU usage and result in slower response times. * When a machine is busy performing intensive tasks, it can lead to slower loading of web pages. In these scenarios, content the web app attempts to load will be in competition with other work happening on the system. This makes it difficult to detect if performance issues exist within web applications themselves, or because of external factors. Teams we have worked with have been surprised at the difference between real-world dashboard metrics and what they observe in page profiling tools. Without more information, it is challenging for developers to understand if (and when) their applications may be misbehaving or are simply being loaded in a contended period. A new ‘confidence’ field on the PerformanceNavigationTiming object will enable developers to discern if the navigation timings are representative for their web application.
▹ Permission Element
PermissionElementchromestatus.comProvide a new HTML element that interacts with the permission flow. The permission prompt is currently triggered directly from JS without the user agent having any strong signal of the user's intent. Having an in-content element that the user uses to trigger the permission flow allows for improved permission prompt UX for users as well as a recovery path from the "denied" permission state for sites. Explainer: https://github.com/WICG/PEPC/blob/main/explainer.md Instructions: https://github.com/WICG/PEPC/blob/main/HOWTO.md Developer facing documentation: https://developer.chrome.com/blog/permission-element-origin-trial
▹ Preferred Audio Output Devices
PreferredAudioOutputDeviceschromestatus.comThis feature adds setDefaultSinkId() to MediaDevices, which enables the top-level frame to change the default audio output device used by its subframes.
▹ Private Aggregation Api Error Reporting
PrivateAggregationApiErrorReportingchromestatus.comThere are a range of error conditions that can be hit when using the Private Aggregation API. For example, the privacy budget could run out, preventing any further histogram contributions. This feature allows developers to register histogram contributions that should only be sent if a particular type of error occurs. This feature supports measuring the frequency of the error conditions and to split these measurements on relevant developer-specified dimensions (e.g. version of deployed code). As the errors themselves may be cross-site information, we cannot simply expose them to the page for users without third-party cookies. Instead, this feature reuses the existing aggregate, noised reporting pipelines through the Aggregation Service.
▹ Private Network Access Null Ip Address
PrivateNetworkAccessNullIpAddresschromestatus.comWe propose to block access to IP address 0.0.0.0 in advance of PNA completely rolling out. Chrome is deprecating direct access to private network endpoints from public websites as part of the Private Network Access (PNA) specification (https://developer.chrome.com/blog/private-network-access-preflight/). Services listening on the localhost (127.0.0.0/8) are considered private according to the specification (https://wicg.github.io/private-network-access/#ip-address-space-heading). Chrome's PNA protection (rolled out as part of https://chromestatus.com/feature/5436853517811712) can be bypassed using the IP address 0.0.0.0 to access services listening on the localhost on macOS and Linux. This can also be abused in DNS rebinding attacks targeting a web application listening on the localhost. Since 0.0.0.0 is not used in practice (and should not be used), but was overlooked during https://chromestatus.com/feature/5436853517811712, we're deprecating it separately from the rest of the private network requests deprecation.
▹ Propagate Overscroll Behavior From Root
PropagateOverscrollBehaviorFromRootchromestatus.comPropagate overscroll-behavior from the root instead of the body. The CSS working group resolved[0] on not propagating properties from the <body> to the viewport. Rather, properties of the viewport are to be propagated from the root (i.e. <html>) element e.g. scroll-behavior[1], scroll-snap-type[2], scroll-padding[3]. As such, overscroll-behavior should be propagated from the root element. However, Chrome has had a longstanding issue of propagating overscroll-behavior from the <body> rather than the root, which deviates from the behavior of Safari(WebKit) and Firefox(Gecko). This feature intends to fix this by propagating overscroll-behavior from the root rather than the <body>. [0] https://github.com/w3c/csswg-drafts/issues/6079#issuecomment-816307011 [1] https://drafts.csswg.org/css-overflow/#:~:text=not%20propagated%20to%20the%20viewport [2] https://drafts.csswg.org/css-scroll-snap/#:~:text=not%20propagated%20from%20HTML%20body [3] https://drafts.csswg.org/css-scroll-snap/#:~:text=padding%20values%20are%20not%20propagated%20from%20HTML%20body
▹ Readable Stream B Y O B Reader Read Min Option
ReadableStreamBYOBReaderReadMinOptionchromestatus.comThis feature introduces a min option to the existing ReadableStreamBYOBReader.read(view) API. The API already accepts a ArrayBufferView into which data is read, but currently does not guarantee how many elements will be written before the read resolves. The min option is an additive, opt-in enhancement - it does not affect existing behavior for applications that don’t use it. By specifying a min value, developers can require that the stream wait until at least that many elements are available before resolving the read. This improves upon the current behavior, where reads may resolve with fewer elements than the view can hold.
▹ Rel Opener Bcg Dependency Hint
RelOpenerBcgDependencyHintchromestatus.comExtends the use of the "opener" rel type to same-window navigations to signal to the browser that the destination page will open a new window and the referring page expects to be able to access it. Some user agents perform browsing context group changes on navigation that aren't strictly necessary for security in order to improve performance. This results in named window reuse not being possible across a back navigation. Annotating an anchor element with "opener" will signal to the user agent that performing a browsing context group change would break a future opener relationship.
▹ Resource Timing Initiator
ResourceTimingInitiatorchromestatus.comIn performanceResourceTiming, expose the "initiator info". "Initiator info" is information on what other resource caused the fetch of the current resource. This information can be used to construct the dependency of the resources from RUM(real user monitoring) data. It helps web sites and CDN to optimize resource delivery speed. It helps security products to track rogue resources too.
▹ Restrict Own Audio
RestrictOwnAudiochromestatus.comrestrictOwnAudio is a captured display surfaces constrainable property. This constrainable property changes the behavior of system audio in a captured display surface. The restrictOwnAudio constraint will only have an effect if the captured display surface inherently includes system audio; otherwise, it will have no impact. By default, when system audio is captured, it includes all audio played out by the system on audio output devices. When restrictOwnAudio is enabled, the captured system audio will be filtered to exclude audio originating from the document that performed getDisplayMedia. The restrictOwnAudio constraint allows for cleaner screen recordings for some use cases. Without it, if the capturing web page itself is playing audio (e.g. a video embedded on the on the recording page), that audio would be included in the capture. This could lead to an undesirable echo or interfere with the intended audio sources from other tabs or applications. The restrictOwnAudio constrainable property is described in the specification. https://www.w3.org/TR/screen-capture/#dfn-restrictownaudio
▹ RTC Data Channel Priority
RTCDataChannelPrioritychromestatus.comMany applications have multiple media flows of the same data type and often some of the flows are more important than others. The priority setting can be used to indicate the relative priority of various flows. The priority API allows the JavaScript applications to tell the browser whether a particular media flow is high, medium, low or of very low importance to the application.
▹ RTC Encoded Frame Set Metadata
RTCEncodedFrameSetMetadatachromestatus.comAllow WebRTC Encoded Transform API to manipulate audio and video frame metadata. Some WebRTC Encoded Transform use cases involve manipulation of not only the payload of encoded video / audio frames but also its metadata. Some examples: * Altering the timestamp of a frame to introduce a delay, * Changing the mime type of the frame if the transform changes the type of the payload. * Forwarding of media to a new peer connection set up to use different metadata values Use cases: https://w3c.github.io/webrtc-nv-use-cases/#live-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#stored-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#auction Issue link: https://github.com/w3c/webrtc-nv-use-cases/issues/77
▹ RTC Rtp Script Transform
RTCRtpScriptTransformchromestatus.comThis API allows processing of encoded media flowing through an RTCPeerConnection. Chromium shipped an early version of this API in 2020. Since then, the spec has changed and other browsers have shipped the updated version of the spec (Safari in 2022 and Firefox in 2023). This launch refers to the latest spec version and is part of Interop 2025. This launch does not cover the generateKeyFrame method, which is still under discussion https://github.com/w3c/webrtc-encoded-transform/issues/143 https://github.com/w3c/webrtc-encoded-transform/issues/271 https://github.com/w3c/webrtc-encoded-transform/pull/269
▹ Scoped View Transitions
ScopedViewTransitionschromestatus.comExposes element.startViewTransition() on arbitrary HTML elements. The element establishes a scope for the transition, which means that the transition pseudo-elements are affected by ancestor clips and transforms, and multiple transitions on separate elements can run concurrently.
▹ Scroll Into View Nearest
ScrollIntoViewNearestchromestatus.comThe ScrollIntoViewOptions container option allows developers to perform a scrollIntoView only scrolling the nearest ancestor scroll container. For example, the following snippet only scrolls the scroll container of target to bring target into view, but will not scroll all of the scroll containers to the viewport: target.scrollIntoView({container: 'nearest'});
▹ Search Text Highlight Pseudo
SearchTextHighlightPseudochromestatus.comExposes find-in-page search result styling to authors as a highlight pseudo-element, like selection and spelling errors. This allows authors to change the foreground and background colors or add text decorations, which can be especially useful if the UA defaults have insufficient contrast with the page colors or are otherwise unsuitable.
▹ Secure Payment Confirmation Browser Bound Keys
SecurePaymentConfirmationBrowserBoundKeyschromestatus.comAdds an additional cryptographic signature over Secure Payment Confirmation assertions and credential creation. The corresponding private key is not synced across devices. This helps web developers meet requirements for device binding for payment transactions.
▹ Shadow Root Reference Target
ShadowRootReferenceTargetchromestatus.comReference Target is a feature to enable using IDREF attributes such as `for` and `aria-labelledby` to refer to elements inside a component's shadow DOM, while maintaining encapsulation of the internal details of the shadow DOM. The main goal of this feature is to enable ARIA to work across shadow root boundaries. A component can specify an element in its shadow tree to act as its "reference target". When the host component is the target of a IDREF like a label's `for` attribute, the reference target becomes the effective target of the label. The shadow root specifies the ID of the target element inside the shadow DOM. This is done either in JavaScript with the `referenceTarget` attribute on the `ShadowRoot` object, or in HTML markup using the `shadowrootreferencetarget` attribute on the `<template>` element.
▹ Shared Worker Extended Lifetime
SharedWorkerExtendedLifetimechromestatus.comThis adds a new option, `extendedLifetime: true`, to the `SharedWorker` constructor. This requests that the shared worker be kept alive even after all current clients have unloaded. The primary use case is to allow pages to perform asynchronous work that requires JavaScript after a page unloads, without needing to rely on a service worker.
▹ Signature Based Integrity
SignatureBasedIntegritychromestatus.comThis feature provides web developers with a mechanism to verify the provenance of resources they depend upon, creating a technical foundation for trust in a site's dependencies. In short: servers can sign responses with a Ed25519 key pair, and web developers can require the user agent to verify the signature using a specific public key. This offers a helpful addition to URL-based checks offered by Content Security Policy on the one hand, and Subresource Integrity's content-based checks on the other.
▹ Soft Navigation Heuristics
SoftNavigationHeuristicschromestatus.comExposes the (experimental) soft navigation heuristics to web developers, using both PerformanceObserver and the performance timeline. This feature reports two new performance entries: - "soft-navigation", for user interactions which navigate the page. Defines a new timeOrigin to help slice the performance timeline. - "interaction-contentful-paint", which reports on the loading performance of interactions (beyond just next paint), used as LCP for soft-navigations.
▹ Text Detector
TextDetectorchromestatus.comThe Text Detection API is a subset of the Shape Detection API which provides the ability to detect and optionally transcribe text in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Toggle Event Source
ToggleEventSourcechromestatus.comThe source attribute of ToggleEvents contains the element which triggered the ToggleEvent to be fired, if applicable. For example, if a button element with the popovertarget or commandfor attribute set up to open a popover is clicked by the user, then the ToggleEvent fired on the popover will have its source attribute set to the invoking button.
▹ Tpcd
Tpcdchromestatus.comThis experiment exposes a temporary set of APIs which provide access to browser-determined treatment and control groups to support opt-in server side testing of the third-party cookie deprecation.
▹ Web App Installation
WebAppInstallationchromestatus.comThe Web Install API allows a web site to install a web app (same or cross domain). This functionality allows the creation of web based catalogues that can install PWAs directly from the web and into multiple platforms. https://aka.ms/webinstall
▹ Web App Scope Extensions
WebAppScopeExtensionschromestatus.comAdds a "scope_extensions" web app manifest field that enables web apps to extend their scope to other origins. Example usage: { "name": "Example", "display": "standalone", "start_url": "/index.html", "scope_extensions": [ {"type" : "origin", "origin" : "https://example.com"} ] } This allows sites that control multiple subdomains and top level domains to be presented as a single web app. Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file. { "https://sample-app.com/": { "scope": "/" } }
▹ WebGPU Compatibility Mode
WebGPUCompatibilityModechromestatus.comAdds an opt-in, lightly restricted subset of the WebGPU API capable of running older graphics APIs such as OpenGL and Direct3D11. By opting into this mode and obeying its constraints, developers can extend the reach of their WebGPU applications to many older devices that do not have the modern, explicit graphics APIs that core WebGPU requires. For simple applications, the only required change is to specify the "compatibility" featureLevel when calling requestAdapter. For more advanced applications, some modifications may be necessary to accommodate the mode's restrictions. Since Compatibility mode is a subset, the resulting applications are also valid WebGPU Core applications and will run even on user agents that do not support Compatibility mode.
▹ WebGPU Experimental Features
WebGPUExperimentalFeatureschromestatus.comFunctionality added to the WebGPU spec after its first shipment in a browser. ServiceWorker and SharedWorker support is added to WebGPU, aligning with existing WebGL capabilities.
▹ Web Identity Digital Credentials
WebIdentityDigitalCredentialschromestatus.comWebsites can and do get credentials from mobile wallet apps through a variety of mechanisms today (custom URL handlers, QR code scanning, etc.). This Web Platform feature would allow sites to request identity information from wallets via Android's IdentityCredential CredMan system. It is extensible to support multiple credential formats (eg. ISO mDoc and W3C verifiable credential) and allows multiple wallet apps to be used. Mechanisms are being added to help reduce the risk of ecosystem-scale abuse of real-world identity (see https://docs.google.com/document/u/1/d/1L68tmNXCQXucsCV8eS8CBd_F9FZ6TNwKNOaFkA8RfwI/edit).
▹ Web Preferences
WebPreferenceschromestatus.comThe Web Preference API aims to provide a way for sites to override the value for a given user preference (e.g. color-scheme preference) in a way that fully integrates with existing Web APIs.
▹ Web Speech Recognition Context
WebSpeechRecognitionContextchromestatus.comThis feature enables websites to support contextual biasing for speech recognition by adding a recognition phrase list to the Web Speech API. Developers can provide a list of phrases as well as updating them to apply a bias to the speech recognition models in favor of those phrases. This helps improve accuracy and relevance for domain-specific and personalized speech recognition.
▹ Web XR Layers
WebXRLayerschromestatus.comWebXR Layers offers a more efficient way of drawing immersive content. In addition to support for native color and depth textures and texture arrays, it also provides support for different layer types that are managed by the system compositor (as opposed to javascript).
▹ Web XR Spec Parity
WebXRSpecParitychromestatus.comUpdates our implementation of the WebXR specification to provide a few attributes that have been added over time. These are generally attributes that developers find useful or enable small performance improvements. These include but are not limited to: Setting/Querying the framerate on an XRSession (including supported framerates), Angular/Linear Velocities, Predicted Display Time of a Frame, isSystemKeyboardSupported, and XRWebGLLayer fixedFoveation
▹ Width And Height As Presentation Attributes On Nested Svg
WidthAndHeightAsPresentationAttributesOnNestedSvgchromestatus.comThis feature supports applying width and height as presentation attributes on nested <svg> elements through both SVG markup and CSS. This dual approach provides even greater flexibility for developers, allowing them to manage and style SVG elements more efficiently within complex designs. With this feature the below two html will now have the same output: With CSS Properties for nested <svg> element: <svg width="100px" height="100px"> <svg style="width:50px;height:50px;"> <circle cx="50px" cy="50px" r="40px" fill="green" /> </svg> </svg> Without CSS Properties for nested <svg> element: <svg width="100px" height="100px"> <svg width="50px" height="50px"> <circle cx="50px" cy="50px" r="40px" fill="green" /> </svg> </svg>

Chromium 138 Polypane 25.1.1
▹ Audio Context Playout Stats
AudioContextPlayoutStatschromestatus.comThe AudioContext.playoutStats API allows an application to measure the quality and latency of audio playout using WebAudio.
▹ Blocking Focus Without User Activation
BlockingFocusWithoutUserActivationchromestatus.comA permissions policy to restrict the use of programmatic focus, when not triggered by a user activation. The proposed policy provides a way to control access to the focus API without user activation. The immediate use case would be restricting all sandboxed frames. Focus API, in this context refers to focus management API and autofocus.
▹ Boundary Event Dispatch Tracks Node Removal
BoundaryEventDispatchTracksNodeRemovalchromestatus.comAfter an event target gets removed from the DOM, the logical target of the pointer as implied by the Pointer and Mouse boundary events (i.e. over, out, enter and leave events) should be the nearest ancestor still attached to the DOM. PEWG has recently reached consensus on this behavior, see https://github.com/web-platform-tests/interop/issues/380. Chrome has been keeping track of a node even after it gets removed from DOM. As a result, if the pointer moves to a new node B after the hit-test node A is removed from DOM, the boundary event sequence (pointerover, pointerout, pointerenter, pointerleave events and the corresponding mouse events) used to imply a pointer movement from A to B. As per the new consensus, the event sequence should imply a pointer movement from the "parent of A" to B.
▹ Canvas Text Ng
CanvasTextNgchromestatus.comThis is not a web-exposed change. The implementation of CanvasRenderingContext2D's measureText(), fillText(), and strokeText() has a drastic change. This might affect performance, so we'd like to run an origin trial so canvas-heavy applications can try out the new implementation.
▹ Capability Delegation Display Capture Request
CapabilityDelegationDisplayCaptureRequestchromestatus.comThis feature is based on the general delegation mechanism (https://chromestatus.com/feature/5708770829139968) shipped on M100. Display-Capture Capability Delegation allows a Window to transfer the ability to call navigator.mediaDevices.getDisplayMedia() to another Window it trusts after relinquishing the transient user activation at the sender Window.
▹ Container Timing
ContainerTimingchromestatus.comThe Container Timing API enables monitoring when annotated sections of the DOM are displayed on screen and have finished their initial paint. A developer will have the ability to mark subsections of the DOM with the containertiming attribute (similar to elementtiming for the Element Timing API) and receive performance entries when that section has been painted for the first time. This API will allow developers to measure the timing of various components in their pages.
▹ Context Menu
ContextMenuchromestatus.comChange “click”, “contextmenu”, “auxclick” events to PointerEvent (instead of MouseEvent) to let developers: distinguish between mouse, pen and individual fingers in a multitouch interaction through pointerType and pointerId attributes, and utilize fractional event coordinates for high precision use cases.
▹ Controlled Frame
ControlledFramechromestatus.comAdds a Controlled Frame API available only to Isolated Web Apps (IWAs). This work adds a new Controlled Frame API which is only available to Isolated Web Apps (IWAs). Like similarly-named APIs on other platforms, Controlled Frame allows embedding all content, even third party content that can't be embedded in <iframe>. Controlled Frame also allows controlling embedded content with a collection of API methods and events. For more info on Isolated Web Apps, see the IWA explainer: https://github.com/WICG/isolated-web-apps/blob/main/README.md
▹ CSS Alt Counter
CSSAltCounterchromestatus.comcounter() and counters() in alt text of 'content' property is useful to provide more meaningful information to e.g. pseudo-elements to improve their accessibility.
▹ CSS Caret Animation
CSSCaretAnimationchromestatus.comChromium supports animation of the caret-color property, but when animated the default blinking behavior of the caret interferes with the animation. For instance, see the example at https://drafts.csswg.org/css-ui/#caret-animation where an animation from blue to red and back is rendered as a blinking cursor that is randomly blue or red. The CSS caret-animation property has two possible values: auto and manual, where auto means browser default (blinking) and manual means the page author is controlling the caret animation. In addition, via a user stylesheet, it allows users who are disturbed by or have adverse reactions to blinking or flashing visuals to disable the blinking.
▹ CSS Corner Shape
CSSCornerShapechromestatus.comEnable styling corners, on top of the existing border-radius, by expressing the shape/curvature of the corner as a superellipse. This allows shapes like squircles, notches, scoops etc., and animating between them.
▹ CSS Fallback Container Queries
CSSFallbackContainerQuerieschromestatus.comIntroduce @container anchored(fallback) to style descendants of anchor positioned elements based on which of position-try-fallbacks is applied. Such queries can be used to e.g. style an anchored element's tether, its animations, etc. based on how the anchor and the anchored element are positioned relative to each other. Example: #anchored { position-try-options: flip-block; container-type: anchored; } @container anchored(fallback: flip-block) { #anchored { --arrow-rotation: 180deg; } }
▹ CSS Functions
CSSFunctionschromestatus.comCustom Functions are similar to custom properties, but instead of returning a single, fixed value, they return values based on other custom properties, parameters, and conditionals.
▹ CSS Short Circuit Var Attr
CSSShortCircuitVarAttrchromestatus.comWhen the fallback is not taken, var()/attr() functions evaluate without looking for cycles in that fallback.
▹ CSS Text Auto Space
CSSTextAutoSpacechromestatus.comInserts small spacings to match the established typographic rules automatically. The spec currently defines one rule for Han ideographic characters and one for French. The initial implementation focuses on the Han ideographic characters rule. Text written in Han ideographic writing systems often mixes multiple scripts, usually the Han ideographic scripts, Latin scripts, and ASCII digits. Small spacings when switching from and to non-Han ideographic scripts often help the readability. This property lets browsers insert such spacings automatically. This property has several values, including values for other writing systems. The initial implementation supports `normal` and `no-autospace`. The initial value is set to `no-autospace` to start conservatively and be more careful for the site compatibilities. Authors can add `text-autospace: normal` to enable the feature.
▹ CSS View Transition Auto Name
CSSViewTransitionAutoNamechromestatus.comContact emails vmpstr@chromium.org, nrosenthal@chromium.org Explainer None Specification https://drafts.csswg.org/css-view-transitions-2/#auto-vt-name Summary 'auto' uses the element's id attribute to generate a unique match for view transition cases. In absence of the id, it generates a unique id based on the element's identity and remains the same for this element. This is used in Single Page App or Multi Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ Device Attributes Permission Policy
DeviceAttributesPermissionPolicychromestatus.comThe new Permissions Policy enables restricting access to the Device Attributes API, which is available only for policy-installed kiosk web apps and policy-installed Isolated Web Apps, both only on managed ChromeOS devices. Additionally, the feature is controlled by content settings. 2 new policies are introduced: DeviceAttributesBlockedForOrigins and DefaultDeviceAttributesSetting, to complement the introduced earlier DeviceAttributesAllowedForOrigins. The feature is enabled by default for the supported scenarios described above.
▹ Device Orientation Request Permission
DeviceOrientationRequestPermissionchromestatus.comAllows developers to ask for permission to use the Device Orientation and Device Motion APIs. Access to these APIs is currently granted by default, and these new functions are part of the long-term plan to require requesting permission before using window.ondevicemotion and window.ondeviceorientation.
▹ Dialog New Focus Behavior
DialogNewFocusBehaviorchromestatus.comSome changes are being made to which element is selected to get focus when a dialog element is opened: 1. Make the dialog focusing steps look at keyboard focusable elements instead of any focusable element. 2. Make the dialog element itself get focus if it has the autofocus attribute set. 3. Make the dialog element itself get focus as a fallback instead of focus being "reset" to the body element.
▹ Document Isolation Policy
DocumentIsolationPolicychromestatus.comDocument-Isolation-Policy allows a document to enable crossOriginIsolation for itself, without having to deploy COOP or COEP, and regardless of the crossOriginIsolation status of the page. The policy is backed by process isolation. Additionally, the document non-CORS cross-origin subresources will either be loaded without credentials or will need to have a CORP header.
▹ Escape Lt Gt In Attributes
EscapeLtGtInAttributeschromestatus.comEscape "<" and ">" in values of attributes on serialization. This mitigates the risk of mutation XSS attacks, which occur when value of an attribute is interpreted as a start tag token after being serialized and re-parsed.
▹ Extended Text Metrics
ExtendedTextMetricschromestatus.comExpand the TextMetrics Canvas API to support selection rectangles, bounding box queries, and grapheme cluster-based operations. This new functionality should enable complex text editing applications with accurate selection, caret positioning, and hit testing. Additionally, cluster-based rendering facilitates sophisticated text effects such as independent character animations and styling.
▹ Face Detector
FaceDetectorchromestatus.comThe Face Detection API is a subset of the Shape Detection API which provides the ability to detect human faces and facial landmarks in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Fetch Retry
FetchRetrychromestatus.comAllow web developers to indicate that a fetch() request should be retried, to have a greater guarantee on it being reliably sent, even if network is flaky. This is especially important for keepalive fetches, where the request might outlive the document, which can no longer watch for its failure and do manual retry. We intend to only support this for keepalive fetches for now because of implementation simplicity, and also the fact that all the use cases would benefit from being keepalive first.
▹ File System Access API Experimental
FileSystemAccessAPIExperimentalchromestatus.comCurrently, the File System Access API does not support an efficient way to move or rename files or directories. This requires creating a new file/directory, copying over data (recursively, in the case of a directory), and removing the original. This process is slow, error prone (e.g. disk full), and can require re-uploading files in some cases. See https://github.com/WICG/file-system-access/pull/317
▹ Focusgroup
Focusgroupchromestatus.comThe Focusgroup feature will facilitate keyboard focus navigation using the keyboard arrow keys among a set of focusable elements.
▹ Gamepad Multitouch
GamepadMultitouchchromestatus.comExtend the Gamepad API to support multitouch surfaces (touchpads). Providing a touchpad API eases application implementation and provides greater functionality browser interoperability.
▹ Heading Offset
HeadingOffsetchromestatus.comA system for creating structured headings within a document. The `headingoffset=` attribute can be added to elements that influences the child `h1`-`h6` elements' heading levels, for example a `headingoffset=1` will mean all `h1` elements will have an effective heading level of 2, and so on. In addition the `:heading` pseudo class will select all headings (tags of `h1` to `h6`) and the `:heading(N)` pseudo class will select headings with an _effective_ level of `N`. This allows for documents with different heading structures (for example user generated content) to be combined to create a well defined heading structure without significantly altering the underlying documents.
▹ HTML Command Request Close
HTMLCommandRequestClosechromestatus.comDialog elements can be closed through a variety of mechanisms, sometimes developers want to have the ability to prevent closure. To achieve this dialogs fire a cancel event. Originally this was only fired via a close request (e.g. ESC key press), recently a `requestClose()` JS function was added which also fires the cancel event. The 'request-close' command brings that new ability to the declarative invoker commands API.
▹ Indexed Db Get All Records
IndexedDbGetAllRecordschromestatus.comThis feature adds the getAllRecords() API to IndexedDB's IDBObjectStore and IDBIndex. It also adds a direction parameter to getAll() and getAllKeys(). This functionality enables certain read patterns to be significantly faster when compared to the existing alternative of iteration with cursors. One key workload from a Microsoft property showed a 350ms improvement. getAllRecords() effectively combines getAllKeys() and getAll() by enumerating both primary keys and values at the same time. For an IDBIndex, getAllRecords() also provides the record's index key in addition to the primary key and value. getAllRecords() can optionally return records in either ascending or descending order. This option is also back-ported to the existing operations getAll() and getAllKeys().
▹ Install On Device Speech Recognition
InstallOnDeviceSpeechRecognitionchromestatus.comThis feature adds on-device speech recognition support to the Web Speech API, allowing websites to ensure that neither audio nor transcribed speech are sent to a third-party service for processing. Websites can query the availability of on-device speech recognition for specific languages, prompt users to install the necessary resources for on-device speech recognition, and choose between on-device or cloud-based speech recognition as needed.
▹ Inverted Colors
InvertedColorschromestatus.comAdds the `inverted-colors` media feature, an indication that the user agent or underlying operating system has forcibly inverted all colors, not a request to do so. This is sometimes provided as a simple accessibility feature, allowing users to switch between light-on-dark and dark-on-light text. Valid options are 'inverted' or 'none'.
▹ Media Capture Background Blur
MediaCaptureBackgroundBlurchromestatus.comThe Background Blur API allows web developers to use the native platform's API for camera background segmentation. As Background Blur has become one of the most used features on video conferencing apps like Teams, Meet, Zoom, and Webex, we want web apps to leverage the same platform APIs without completely relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud based solutions.
▹ Media Capture Voice Isolation
MediaCaptureVoiceIsolationchromestatus.comThis is about adding support in Chrome for the VoiceIsolation getUserMedia constraint (https://w3c.github.io/mediacapture-extensions/#voiceisolation-constraint). The constraint only takes effect on platforms where there is low-level support for voice-isolation style denoising. Currently this is limited to a selected number of ChromeOS devices, but further platforms will be added.
▹ Media Source Extensions For Web Codecs
MediaSourceExtensionsForWebCodecschromestatus.comExtends the Media Source Extensions API (MSE) to enable buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.
▹ Multicol Column Wrapping
MulticolColumnWrappingchromestatus.comAdd support for the `column-wrap` and `column-height` CSS properties, from multicol Level 2. https://drafts.csswg.org/css-multicol-2/#cwr https://drafts.csswg.org/css-multicol-2/#ch This allows for vertical column layout, or even 2D column layout. Columns can have an explicit constrained height, apart from being derived from the content-box height of the multicol container, and wrap to a new row of columns when all columns have been filled for one row, rather than creating overflowing columns in the inline direction.
▹ Navigate Event Commit Behavior
NavigateEventCommitBehaviorchromestatus.comNormally, when navigateEvent.intercept() is called, the intercepted navigation commits (and therefore the URL updates) as soon as the NavigateEvent finishes dispatch. Adding a `precommitHandler` option to navigateEvent.intercept(), similar to `handler`, would defer the commit until that handler (and all other precommit handlers) are resolved, also allowing the handler to change the navigation's URL, info, status, and history handling behavior (push/replace).
▹ Navigation Id
NavigationIdchromestatus.comThis adds a Performance Timeline entry type, "back-forward-cache-restoration", which is emitted every time that a page is retrieved from the back-forward cache, and a field on all performance timeline entries, "navigationId", which can be used to tie performance events to the most recent navigation-like event. This allows developers to more easily use the performance APIs to compare the user experience of an SPA or a bfcache-eligible page with that of a traditional multi-page experience.
▹ Nested View Transition
NestedViewTransitionchromestatus.comAllow view-transitions to generate a nested pseudo-element tree rather than a flat one. This allows the view transition to appear more in line with its original elements and visual intent, as it enables clipping, nested 3D transforms, and proper application of effects like opacity, masking and filters.
▹ On Device Web Speech Available
OnDeviceWebSpeechAvailablechromestatus.comThis feature enables websites to support contextual biasing for speech recognition by adding a recognition phrase list to the Web Speech API. Developers can provide a list of phrases as well as updating them to apply a bias to the speech recognition models in favor of those phrases. This helps improve accuracy and relevance for domain-specific and personalized speech recognition.
▹ Paint Timing Mixin
PaintTimingMixinchromestatus.comExpose "paintTime" and "presentationTime" in event timing, element timing, LCP, long animation frames, paint timing. "paintTime" means the time when the rendering phase ended and the browser started the paint phase. "presentationTime" means the time when the "pixels reached the screen", which is somewhat implementation-defined
▹ Payment App
PaymentAppchromestatus.comThe API helps to develop new payment apps in web standard ways (e.g. service worker). If using them, payment app providers can provide simplified payment methods and user experiences.
▹ Payment Link Detection
PaymentLinkDetectionchromestatus.comAdds support for <link rel="facilitated-payment" href="..."> as a hint that the browser should notify registered payment clients about a pending push payment.
▹ Payment Request
PaymentRequestchromestatus.comTo help developers reduce friction in Payment Request flows, we are removing the user activation requirement. Spam and clickjacking mitigations are put in place to mitigate security and privacy risks with this change.
▹ Performance Navigation Timing Confidence
PerformanceNavigationTimingConfidencechromestatus.comWeb applications may suffer from bimodal distribution in page load performance, due to factors outside of the web application’s control. For example: * When a user agent first launches (a "cold start" scenario), it must perform many expensive initialization tasks that compete for resources on the system. * Browser extensions can affect the performance of a website. For instance, some extensions run additional code on every page you visit, which can increase CPU usage and result in slower response times. * When a machine is busy performing intensive tasks, it can lead to slower loading of web pages. In these scenarios, content the web app attempts to load will be in competition with other work happening on the system. This makes it difficult to detect if performance issues exist within web applications themselves, or because of external factors. Teams we have worked with have been surprised at the difference between real-world dashboard metrics and what they observe in page profiling tools. Without more information, it is challenging for developers to understand if (and when) their applications may be misbehaving or are simply being loaded in a contended period. A new ‘confidence’ field on the PerformanceNavigationTiming object will enable developers to discern if the navigation timings are representative for their web application.
▹ Permission Element
PermissionElementchromestatus.comProvide a new HTML element that interacts with the permission flow. The permission prompt is currently triggered directly from JS without the user agent having any strong signal of the user's intent. Having an in-content element that the user uses to trigger the permission flow allows for improved permission prompt UX for users as well as a recovery path from the "denied" permission state for sites. Explainer: https://github.com/WICG/PEPC/blob/main/explainer.md Instructions: https://github.com/WICG/PEPC/blob/main/HOWTO.md Developer facing documentation: https://developer.chrome.com/blog/permission-element-origin-trial
▹ Preferred Audio Output Devices
PreferredAudioOutputDeviceschromestatus.comThis feature adds setDefaultSinkId() to MediaDevices, which enables the top-level frame to change the default audio output device used by its subframes.
▹ Private Aggregation Api Error Reporting
PrivateAggregationApiErrorReportingchromestatus.comThere are a range of error conditions that can be hit when using the Private Aggregation API. For example, the privacy budget could run out, preventing any further histogram contributions. This feature allows developers to register histogram contributions that should only be sent if a particular type of error occurs. This feature supports measuring the frequency of the error conditions and to split these measurements on relevant developer-specified dimensions (e.g. version of deployed code). As the errors themselves may be cross-site information, we cannot simply expose them to the page for users without third-party cookies. Instead, this feature reuses the existing aggregate, noised reporting pipelines through the Aggregation Service.
▹ Private Network Access Null Ip Address
PrivateNetworkAccessNullIpAddresschromestatus.comWe propose to block access to IP address 0.0.0.0 in advance of PNA completely rolling out. Chrome is deprecating direct access to private network endpoints from public websites as part of the Private Network Access (PNA) specification (https://developer.chrome.com/blog/private-network-access-preflight/). Services listening on the localhost (127.0.0.0/8) are considered private according to the specification (https://wicg.github.io/private-network-access/#ip-address-space-heading). Chrome's PNA protection (rolled out as part of https://chromestatus.com/feature/5436853517811712) can be bypassed using the IP address 0.0.0.0 to access services listening on the localhost on macOS and Linux. This can also be abused in DNS rebinding attacks targeting a web application listening on the localhost. Since 0.0.0.0 is not used in practice (and should not be used), but was overlooked during https://chromestatus.com/feature/5436853517811712, we're deprecating it separately from the rest of the private network requests deprecation.
▹ Propagate Overscroll Behavior From Root
PropagateOverscrollBehaviorFromRootchromestatus.comPropagate overscroll-behavior from the root instead of the body. The CSS working group resolved[0] on not propagating properties from the <body> to the viewport. Rather, properties of the viewport are to be propagated from the root (i.e. <html>) element e.g. scroll-behavior[1], scroll-snap-type[2], scroll-padding[3]. As such, overscroll-behavior should be propagated from the root element. However, Chrome has had a longstanding issue of propagating overscroll-behavior from the <body> rather than the root, which deviates from the behavior of Safari(WebKit) and Firefox(Gecko). This feature intends to fix this by propagating overscroll-behavior from the root rather than the <body>.

▹ Rel Opener Bcg Dependency Hint
RelOpenerBcgDependencyHintchromestatus.comExtends the use of the "opener" rel type to same-window navigations to signal to the browser that the destination page will open a new window and the referring page expects to be able to access it. Some user agents perform browsing context group changes on navigation that aren't strictly necessary for security in order to improve performance. This results in named window reuse not being possible across a back navigation. Annotating an anchor element with "opener" will signal to the user agent that performing a browsing context group change would break a future opener relationship.
▹ Restrict Own Audio
RestrictOwnAudiochromestatus.comrestrictOwnAudio is a captured display surfaces constrainable property. This constrainable property changes the behavior of system audio in a captured display surface. The restrictOwnAudio constraint will only have an effect if the captured display surface inherently includes system audio; otherwise, it will have no impact. By default, when system audio is captured, it includes all audio played out by the system on audio output devices. When restrictOwnAudio is enabled, the captured system audio will be filtered to exclude audio originating from the document that performed getDisplayMedia. The restrictOwnAudio constraint allows for cleaner screen recordings for some use cases. Without it, if the capturing web page itself is playing audio (e.g. a video embedded on the on the recording page), that audio would be included in the capture. This could lead to an undesirable echo or interfere with the intended audio sources from other tabs or applications. The restrictOwnAudio constrainable property is described in the specification. https://www.w3.org/TR/screen-capture/#dfn-restrictownaudio
▹ RTC Data Channel Priority
RTCDataChannelPrioritychromestatus.comMany applications have multiple media flows of the same data type and often some of the flows are more important than others. The priority setting can be used to indicate the relative priority of various flows. The priority API allows the JavaScript applications to tell the browser whether a particular media flow is high, medium, low or of very low importance to the application.
▹ RTC Encoded Frame Set Metadata
RTCEncodedFrameSetMetadatachromestatus.comAllow WebRTC Encoded Transform API to manipulate audio and video frame metadata. Some WebRTC Encoded Transform use cases involve manipulation of not only the payload of encoded video / audio frames but also its metadata. Some examples: * Altering the timestamp of a frame to introduce a delay, * Changing the mime type of the frame if the transform changes the type of the payload. * Forwarding of media to a new peer connection set up to use different metadata values Use cases: https://w3c.github.io/webrtc-nv-use-cases/#live-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#stored-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#auction Issue link: https://github.com/w3c/webrtc-nv-use-cases/issues/77
▹ RTC Rtp Script Transform
RTCRtpScriptTransformchromestatus.comThis API allows processing of encoded media flowing through an RTCPeerConnection. Chromium shipped an early version of this API in 2020. Since then, the spec has changed and other browsers have shipped the updated version of the spec (Safari in 2022 and Firefox in 2023). This launch refers to the latest spec version and is part of Interop 2025. This launch does not cover the generateKeyFrame method, which is still under discussion https://github.com/w3c/webrtc-encoded-transform/issues/143 https://github.com/w3c/webrtc-encoded-transform/issues/271 https://github.com/w3c/webrtc-encoded-transform/pull/269
▹ Scoped View Transitions
ScopedViewTransitionschromestatus.comExposes element.startViewTransition() on arbitrary HTML elements. The element establishes a scope for the transition, which means that the transition pseudo-elements are affected by ancestor clips and transforms, and multiple transitions on separate elements can run concurrently.
▹ Scroll Into View Nearest
ScrollIntoViewNearestchromestatus.comThe ScrollIntoViewOptions container option allows developers to perform a scrollIntoView only scrolling the nearest ancestor scroll container. For example, the following snippet only scrolls the scroll container of target to bring target into view, but will not scroll all of the scroll containers to the viewport: target.scrollIntoView({container: 'nearest'});
▹ Search Text Highlight Pseudo
SearchTextHighlightPseudochromestatus.comExposes find-in-page search result styling to authors as a highlight pseudo-element, like selection and spelling errors. This allows authors to change the foreground and background colors or add text decorations, which can be especially useful if the UA defaults have insufficient contrast with the page colors or are otherwise unsuitable.
▹ Secure Payment Confirmation Browser Bound Keys
SecurePaymentConfirmationBrowserBoundKeyschromestatus.comAdds an additional cryptographic signature over Secure Payment Confirmation assertions and credential creation. The corresponding private key is not synced across devices. This helps web developers meet requirements for device binding for payment transactions.
▹ Shadow Root Reference Target
ShadowRootReferenceTargetchromestatus.comReference Target is a feature to enable using IDREF attributes such as `for` and `aria-labelledby` to refer to elements inside a component's shadow DOM, while maintaining encapsulation of the internal details of the shadow DOM. The main goal of this feature is to enable ARIA to work across shadow root boundaries. A component can specify an element in its shadow tree to act as its "reference target". When the host component is the target of a IDREF like a label's `for` attribute, the reference target becomes the effective target of the label. The shadow root specifies the ID of the target element inside the shadow DOM. This is done either in JavaScript with the `referenceTarget` attribute on the `ShadowRoot` object, or in HTML markup using the `shadowrootreferencetarget` attribute on the `<template>` element.
▹ Signature Based Integrity
SignatureBasedIntegritychromestatus.comThis feature provides web developers with a mechanism to verify the provenance of resources they depend upon, creating a technical foundation for trust in a site's dependencies. In short: servers can sign responses with a Ed25519 key pair, and web developers can require the user agent to verify the signature using a specific public key. This offers a helpful addition to URL-based checks offered by Content Security Policy on the one hand, and Subresource Integrity's content-based checks on the other.
▹ Soft Navigation Heuristics
SoftNavigationHeuristicschromestatus.comExposes the (experimental) soft navigation heuristics to web developers, using both PerformanceObserver and the performance timeline. This feature reports two new performance entries: - "soft-navigation", for user interactions which navigate the page. Defines a new timeOrigin to help slice the performance timeline. - "interaction-contentful-paint", which reports on the loading performance of interactions (beyond just next paint), used as LCP for soft-navigations.
▹ Text Detector
TextDetectorchromestatus.comThe Text Detection API is a subset of the Shape Detection API which provides the ability to detect and optionally transcribe text in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Toggle Event Source
ToggleEventSourcechromestatus.comThe source attribute of ToggleEvents contains the element which triggered the ToggleEvent to be fired, if applicable. For example, if a button element with the popovertarget or commandfor attribute set up to open a popover is clicked by the user, then the ToggleEvent fired on the popover will have its source attribute set to the invoking button.
▹ Tpcd
Tpcdchromestatus.comThis experiment exposes a temporary set of APIs which provide access to browser-determined treatment and control groups to support opt-in server side testing of the third-party cookie deprecation.
▹ Web App Installation
WebAppInstallationchromestatus.comThe Web Install API allows a web site to install a web app (same or cross domain). This functionality allows the creation of web based catalogues that can install PWAs directly from the web and into multiple platforms. https://aka.ms/webinstall
▹ Web App Scope Extensions
WebAppScopeExtensionschromestatus.comAdds a "scope_extensions" web app manifest field that enables web apps to extend their scope to other origins. Example usage: { "name": "Example", "display": "standalone", "start_url": "/index.html", "scope_extensions": [ {"type" : "origin", "origin" : "https://example.com"} ] } This allows sites that control multiple subdomains and top level domains to be presented as a single web app. Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file. { "https://sample-app.com/": { "scope": "/" } }
▹ WebGPU Compatibility Mode
WebGPUCompatibilityModechromestatus.comAdds an opt-in, lightly restricted subset of the WebGPU API capable of running older graphics APIs such as OpenGL and Direct3D11. By opting into this mode and obeying its constraints, developers can extend the reach of their WebGPU applications to many older devices that do not have the modern, explicit graphics APIs that core WebGPU requires. For simple applications, the only required change is to specify the "compatibility" featureLevel when calling requestAdapter. For more advanced applications, some modifications may be necessary to accommodate the mode's restrictions. Since Compatibility mode is a subset, the resulting applications are also valid WebGPU Core applications and will run even on user agents that do not support Compatibility mode.
▹ WebGPU Experimental Features
WebGPUExperimentalFeatureschromestatus.comFunctionality added to the WebGPU spec after its first shipment in a browser. ServiceWorker and SharedWorker support is added to WebGPU, aligning with existing WebGL capabilities.
▹ Web Identity Digital Credentials
WebIdentityDigitalCredentialschromestatus.comWebsites can and do get credentials from mobile wallet apps through a variety of mechanisms today (custom URL handlers, QR code scanning, etc.). This Web Platform feature would allow sites to request identity information from wallets via Android's IdentityCredential CredMan system. It is extensible to support multiple credential formats (eg. ISO mDoc and W3C verifiable credential) and allows multiple wallet apps to be used. Mechanisms are being added to help reduce the risk of ecosystem-scale abuse of real-world identity (see https://docs.google.com/document/u/1/d/1L68tmNXCQXucsCV8eS8CBd_F9FZ6TNwKNOaFkA8RfwI/edit).
▹ Web Preferences
WebPreferenceschromestatus.comThe Web Preference API aims to provide a way for sites to override the value for a given user preference (e.g. color-scheme preference) in a way that fully integrates with existing Web APIs.
▹ Web XR Depth Performance
WebXRDepthPerformancechromestatus.comExposes several new mechanisms to customize the behavior of the depth sensing feature within a WebXR session, with the goal of improving the performance of the generation or consumption of the depth buffer. The key mechanisms exposed are: the ability to request the raw or smooth depth buffer, the ability to request that the runtime stop or resume providing the depth buffer, and the ability to expose a depth buffer that does not align with the user's view exactly, so that the user agent does not need to perform unnecessary re-projections every frame.
▹ Web XR Layers
WebXRLayerschromestatus.comWebXR Layers offers a more efficient way of drawing immersive content. In addition to support for native color and depth textures and texture arrays, it also provides support for different layer types that are managed by the system compositor (as opposed to javascript).
▹ Web XR Spec Parity
WebXRSpecParitychromestatus.comUpdates our implementation of the WebXR specification to provide a few attributes that have been added over time. These are generally attributes that developers find useful or enable small performance improvements. These include but are not limited to: Setting/Querying the framerate on an XRSession (including supported framerates), Angular/Linear Velocities, Predicted Display Time of a Frame, isSystemKeyboardSupported, and XRWebGLLayer fixedFoveation

Chromium 137
▹ AI Prompt API Multimodal Input
AIPromptAPIMultimodalInputchromestatus.comAn API designed for interacting with an AI language model using text, image, and audio inputs. It supports various use cases, from generating image captions and performing visual searches to transcribing audio, classifying sound events, generating text following specific instructions, and extracting information or insights from text. It supports structured outputs which ensure that responses adhere to a predefined format, typically expressed as a JSON schema, to enhance response conformance and facilitate seamless integration with downstream applications that require standardized output formats. This API is also exposed in Chrome Extensions. This feature entry tracks the exposure on the web. An enterprise policy (GenAILocalFoundationalModelSettings) is available to disable the underlying model downloading which would render this API unavailable. Language support log: - Chrome M139 and earlier only supported 'en' - Chrome M140 added support for 'es' and 'ja'
▹ AI Summarization API
AISummarizationAPIchromestatus.comSummarizer API is a JavaScript API for producing summaries of input text, backed by an AI language model. Browsers and operating systems are increasingly expected to gain access to a language model. By exposing this built-in model, we avoid every website needing to download their own multi-gigabyte language model, or send input text to third-party APIs. The summarizer API in particular exposes a high-level API for interfacing with a language model in order to summarize multilingual inputs for a variety of use cases, in a way that does not depend on the specific language model in question. An enterprise policy (GenAILocalFoundationalModelSettings) is available to disable the underlying model downloading which would render this API unavailable. Language support log: - Chrome M139 and earlier only supported 'en' - Chrome M140 added support for 'es' and 'ja'
▹ Audio Context Playout Stats
AudioContextPlayoutStatschromestatus.comThe AudioContext.playoutStats API allows an application to measure the quality and latency of audio playout using WebAudio.
▹ Blocking Focus Without User Activation
BlockingFocusWithoutUserActivationchromestatus.comA permissions policy to restrict the use of programmatic focus, when not triggered by a user activation. The proposed policy provides a way to control access to the focus API without user activation. The immediate use case would be restricting all sandboxed frames. Focus API, in this context refers to focus management API and autofocus.
▹ Boundary Event Dispatch Tracks Node Removal
BoundaryEventDispatchTracksNodeRemovalchromestatus.comAfter an event target gets removed from the DOM, the logical target of the pointer as implied by the Pointer and Mouse boundary events (i.e. over, out, enter and leave events) should be the nearest ancestor still attached to the DOM. PEWG has recently reached consensus on this behavior, see https://github.com/web-platform-tests/interop/issues/380. Chrome has been keeping track of a node even after it gets removed from DOM. As a result, if the pointer moves to a new node B after the hit-test node A is removed from DOM, the boundary event sequence (pointerover, pointerout, pointerenter, pointerleave events and the corresponding mouse events) used to imply a pointer movement from A to B. As per the new consensus, the event sequence should imply a pointer movement from the "parent of A" to B.
▹ Canvas Text Ng
CanvasTextNgchromestatus.comThis is not a web-exposed change. The implementation of CanvasRenderingContext2D's measureText(), fillText(), and strokeText() has a drastic change. This might affect performance, so we'd like to run an origin trial so canvas-heavy applications can try out the new implementation.
▹ Capability Delegation Display Capture Request
CapabilityDelegationDisplayCaptureRequestchromestatus.comThis feature is based on the general delegation mechanism (https://chromestatus.com/feature/5708770829139968) shipped on M100. Display-Capture Capability Delegation allows a Window to transfer the ability to call navigator.mediaDevices.getDisplayMedia() to another Window it trusts after relinquishing the transient user activation at the sender Window.
▹ Container Timing
ContainerTimingchromestatus.comThe Container Timing API enables monitoring when annotated sections of the DOM are displayed on screen and have finished their initial paint. A developer will have the ability to mark subsections of the DOM with the containertiming attribute (similar to elementtiming for the Element Timing API) and receive performance entries when that section has been painted for the first time. This API will allow developers to measure the timing of various components in their pages.
▹ Context Menu
ContextMenuchromestatus.comChange “click”, “contextmenu”, “auxclick” events to PointerEvent (instead of MouseEvent) to let developers: distinguish between mouse, pen and individual fingers in a multitouch interaction through pointerType and pointerId attributes, and utilize fractional event coordinates for high precision use cases.
▹ Controlled Frame
ControlledFramechromestatus.comAdds a Controlled Frame API available only to Isolated Web Apps (IWAs). This work adds a new Controlled Frame API which is only available to Isolated Web Apps (IWAs). Like similarly-named APIs on other platforms, Controlled Frame allows embedding all content, even third party content that can't be embedded in <iframe>. Controlled Frame also allows controlling embedded content with a collection of API methods and events. For more info on Isolated Web Apps, see the IWA explainer: https://github.com/WICG/isolated-web-apps/blob/main/README.md
▹ CSS Caret Animation
CSSCaretAnimationchromestatus.comChromium supports animation of the caret-color property, but when animated the default blinking behavior of the caret interferes with the animation. For instance, see the example at https://drafts.csswg.org/css-ui/#caret-animation where an animation from blue to red and back is rendered as a blinking cursor that is randomly blue or red. The CSS caret-animation property has two possible values: auto and manual, where auto means browser default (blinking) and manual means the page author is controlling the caret animation. In addition, via a user stylesheet, it allows users who are disturbed by or have adverse reactions to blinking or flashing visuals to disable the blinking.
▹ CSS Corner Shape
CSSCornerShapechromestatus.comEnable styling corners, on top of the existing border-radius, by expressing the shape/curvature of the corner as a superellipse. This allows shapes like squircles, notches, scoops etc., and animating between them.
▹ CSS Functions
CSSFunctionschromestatus.comCustom Functions are similar to custom properties, but instead of returning a single, fixed value, they return values based on other custom properties, parameters, and conditionals.
▹ CSS Preferred Text Scale
CSSPreferredTextScalechromestatus.comExposes a user's preferred font scale to CSS. Currently, it is not practical for a page to detect if the user has changed their preferred font size via the Operating System's preferences. This CSS environment variable will reflect the scale chosen by the user.
▹ CSS Progress Notation
CSSProgressNotationchromestatus.comThe progress() functional notation returns a <number> value representing the position of one calculation (the progress value) between two other calculations (the progress start value and progress end value). progress() is a math function. The syntax of progress() is defined as follows: <progress()> = progress(<calc-sum>, <calc-sum>, <calc-sum>) where the first, second, and third <calc-sum> values represent the progress value, progress start value, and progress end value, respectively.
▹ CSS Sibling Functions
CSSSiblingFunctionschromestatus.comsibling-index() and sibling-count() can be used as integers in CSS property values to style elements based on their position among its siblings, or the total number of siblings respectively. These functions can be used directly as integer values, but more interestingly inside calc() expressions. Example: li { margin-left: calc(10px * sibling-index()); }
▹ CSS Sign Related Functions
CSSSignRelatedFunctionschromestatus.comThe sign-related functions abs() and sign() compute various functions related to the sign of their argument. The abs(A) function contains one calculation A, and returns the absolute value of A, as the same type as the input: if A’s numeric value is positive or 0⁺, just A again; otherwise -1 * A. The sign(A) function contains one calculation A, and returns -1 if A’s numeric value is negative, +1 if A’s numeric value is positive, 0⁺ if A’s numeric value is 0⁺, and 0⁻ if A’s numeric value is 0⁻. The return type is a <number>, made consistent with the input calculation’s type.
▹ CSS System Accent Color
CSSSystemAccentColorchromestatus.comThis feature empowers web developers to enhance the visual appeal of their websites by leveraging the operating system's accent color for form elements. By utilizing the "accent-color" CSS property, developers can ensure that form elements such as checkboxes, radio buttons, and progress bars automatically adopt the accent color defined by the user's operating system. This feature is an enhancement to existing feature that is already shipped in Chromium: https://groups.google.com/a/chromium.org/g/blink-dev/c/WwYkLjbGhoA
▹ CSS Text Auto Space
CSSTextAutoSpacechromestatus.comInserts small spacings to match the established typographic rules automatically. The spec currently defines one rule for Han ideographic characters and one for French. The initial implementation focuses on the Han ideographic characters rule. Text written in Han ideographic writing systems often mixes multiple scripts, usually the Han ideographic scripts, Latin scripts, and ASCII digits. Small spacings when switching from and to non-Han ideographic scripts often help the readability. This property lets browsers insert such spacings automatically. This property has several values, including values for other writing systems. The initial implementation supports `normal` and `no-autospace`. The initial value is set to `no-autospace` to start conservatively and be more careful for the site compatibilities. Authors can add `text-autospace: normal` to enable the feature.
▹ CSS View Transition Auto Name
CSSViewTransitionAutoNamechromestatus.comContact emails vmpstr@chromium.org, nrosenthal@chromium.org Explainer None Specification https://drafts.csswg.org/css-view-transitions-2/#auto-vt-name Summary 'auto' uses the element's id attribute to generate a unique match for view transition cases. In absence of the id, it generates a unique id based on the element's identity and remains the same for this element. This is used in Single Page App or Multi Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ Device Attributes Permission Policy
DeviceAttributesPermissionPolicychromestatus.comThe new Permissions Policy enables restricting access to the Device Attributes API, which is available only for policy-installed kiosk web apps and policy-installed Isolated Web Apps, both only on managed ChromeOS devices. Additionally, the feature is controlled by content settings. 2 new policies are introduced: DeviceAttributesBlockedForOrigins and DefaultDeviceAttributesSetting, to complement the introduced earlier DeviceAttributesAllowedForOrigins. The feature is enabled by default for the supported scenarios described above.
▹ Device Orientation Request Permission
DeviceOrientationRequestPermissionchromestatus.comAllows developers to ask for permission to use the Device Orientation and Device Motion APIs. Access to these APIs is currently granted by default, and these new functions are part of the long-term plan to require requesting permission before using window.ondevicemotion and window.ondeviceorientation.
▹ Dialog New Focus Behavior
DialogNewFocusBehaviorchromestatus.comSome changes are being made to which element is selected to get focus when a dialog element is opened: 1. Make the dialog focusing steps look at keyboard focusable elements instead of any focusable element. 2. Make the dialog element itself get focus if it has the autofocus attribute set. 3. Make the dialog element itself get focus as a fallback instead of focus being "reset" to the body element.
▹ Document Isolation Policy
DocumentIsolationPolicychromestatus.comDocument-Isolation-Policy allows a document to enable crossOriginIsolation for itself, without having to deploy COOP or COEP, and regardless of the crossOriginIsolation status of the page. The policy is backed by process isolation. Additionally, the document non-CORS cross-origin subresources will either be loaded without credentials or will need to have a CORP header.
▹ Escape Lt Gt In Attributes
EscapeLtGtInAttributeschromestatus.comEscape "<" and ">" in values of attributes on serialization. This mitigates the risk of mutation XSS attacks, which occur when value of an attribute is interpreted as a start tag token after being serialized and re-parsed.
▹ Extended Text Metrics
ExtendedTextMetricschromestatus.comExpand the TextMetrics Canvas API to support selection rectangles, bounding box queries, and grapheme cluster-based operations. This new functionality should enable complex text editing applications with accurate selection, caret positioning, and hit testing. Additionally, cluster-based rendering facilitates sophisticated text effects such as independent character animations and styling.
▹ Face Detector
FaceDetectorchromestatus.comThe Face Detection API is a subset of the Shape Detection API which provides the ability to detect human faces and facial landmarks in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ File System Access API Experimental
FileSystemAccessAPIExperimentalchromestatus.comCurrently, the File System Access API does not support an efficient way to move or rename files or directories. This requires creating a new file/directory, copying over data (recursively, in the case of a directory), and removing the original. This process is slow, error prone (e.g. disk full), and can require re-uploading files in some cases. See https://github.com/WICG/file-system-access/pull/317
▹ Focusgroup
Focusgroupchromestatus.comThe Focusgroup feature will facilitate keyboard focus navigation using the keyboard arrow keys among a set of focusable elements.
▹ Gamepad Multitouch
GamepadMultitouchchromestatus.comExtend the Gamepad API to support multitouch surfaces (touchpads). Providing a touchpad API eases application implementation and provides greater functionality browser interoperability.
▹ Heading Offset
HeadingOffsetchromestatus.comA system for creating structured headings within a document. The `headingoffset=` attribute can be added to elements that influences the child `h1`-`h6` elements' heading levels, for example a `headingoffset=1` will mean all `h1` elements will have an effective heading level of 2, and so on. In addition the `:heading` pseudo class will select all headings (tags of `h1` to `h6`) and the `:heading(N)` pseudo class will select headings with an _effective_ level of `N`. This allows for documents with different heading structures (for example user generated content) to be combined to create a well defined heading structure without significantly altering the underlying documents.
▹ HTML Command Request Close
HTMLCommandRequestClosechromestatus.comDialog elements can be closed through a variety of mechanisms, sometimes developers want to have the ability to prevent closure. To achieve this dialogs fire a cancel event. Originally this was only fired via a close request (e.g. ESC key press), recently a `requestClose()` JS function was added which also fires the cancel event. The 'request-close' command brings that new ability to the declarative invoker commands API.
▹ Ignore Letter Spacing In Cursive Scripts
IgnoreLetterSpacingInCursiveScriptschromestatus.comThis feature adds logic to ignore the letter-spacing setting for cursive scripts as specified by the web author, in line with the spec, to ensure that letter spacing does not disrupt word structure and aims to produce better user experience for users relying on cursive scripts. The spec suggests that the UA may apply letter spacing to cursive scripts by translating the total extra space into cursive elongation or compression. Otherwise, if the UA cannot expand text from a cursive script without breaking its cursive connections, it must not apply spacing between any pair of that script’s typographic letter units at all. Ignoring letter spacing altogether for cursive scripts is simpler and helps avoid performance issues as handling spacing for such scripts requires complex calculations to maintain cursive connections and account for script-specific factors like elongation glyphs, typefaces, and calligraphy preferences. With this feature, Chromium ensures that cursive scripts will be readable and properly spaced, even if the fonts don’t have advanced typographic features. The scripts that we are proposing to apply this to in Chromium are Arabic, Hanifi Rohingya, Mandaic, Mongolian, N’Ko, Phags Pa, and Syriac as these scripts are considered cursive as per spec.
▹ Indexed Db Get All Records
IndexedDbGetAllRecordschromestatus.comThis feature adds the getAllRecords() API to IndexedDB's IDBObjectStore and IDBIndex. It also adds a direction parameter to getAll() and getAllKeys(). This functionality enables certain read patterns to be significantly faster when compared to the existing alternative of iteration with cursors. One key workload from a Microsoft property showed a 350ms improvement. getAllRecords() effectively combines getAllKeys() and getAll() by enumerating both primary keys and values at the same time. For an IDBIndex, getAllRecords() also provides the record's index key in addition to the primary key and value. getAllRecords() can optionally return records in either ascending or descending order. This option is also back-ported to the existing operations getAll() and getAllKeys().
▹ Install On Device Speech Recognition
InstallOnDeviceSpeechRecognitionchromestatus.comThis feature adds on-device speech recognition support to the Web Speech API, allowing websites to ensure that neither audio nor transcribed speech are sent to a third-party service for processing. Websites can query the availability of on-device speech recognition for specific languages, prompt users to install the necessary resources for on-device speech recognition, and choose between on-device or cloud-based speech recognition as needed.
▹ Inverted Colors
InvertedColorschromestatus.comAdds the `inverted-colors` media feature, an indication that the user agent or underlying operating system has forcibly inverted all colors, not a request to do so. This is sometimes provided as a simple accessibility feature, allowing users to switch between light-on-dark and dark-on-light text. Valid options are 'inverted' or 'none'.
▹ Language Detection API
LanguageDetectionAPIchromestatus.comA JavaScript API for detecting the language of text, with confidence levels. An important supplement to translation is language detection. This can be combined with translation, e.g. taking user input in an unknown language and translating it to a specific target language. Browsers today often already have langauge detection capabilities, and we want to offer them to web developers through a JavaScript API, supplementing the translation API. An enterprise policy (GenAILocalFoundationalModelSettings) is available to disable the underlying model downloading which would render this API unavailable.
▹ Layout Stretch
LayoutStretchchromestatus.comA keyword for CSS sizing properties (e.g. 'width', 'height') that allows elements to grow to exactly fill their containing block's available space. It is similar to '100%', except the resulting size is applied to the element's margin box instead of the box indicated by 'box-sizing'. Using this keyword allows the element to keep its margins while still being as large as possible. An unprefixed version of '-webkit-fill-available'.
▹ Media Capture Background Blur
MediaCaptureBackgroundBlurchromestatus.comThe Background Blur API allows web developers to use the native platform's API for camera background segmentation. As Background Blur has become one of the most used features on video conferencing apps like Teams, Meet, Zoom, and Webex, we want web apps to leverage the same platform APIs without completely relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud based solutions.
▹ Media Capture Voice Isolation
MediaCaptureVoiceIsolationchromestatus.comThis is about adding support in Chrome for the VoiceIsolation getUserMedia constraint (https://w3c.github.io/mediacapture-extensions/#voiceisolation-constraint). The constraint only takes effect on platforms where there is low-level support for voice-isolation style denoising. Currently this is limited to a selected number of ChromeOS devices, but further platforms will be added.
▹ Media Source Extensions For Web Codecs
MediaSourceExtensionsForWebCodecschromestatus.comExtends the Media Source Extensions API (MSE) to enable buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.
▹ Media Source New Abort And Duration
MediaSourceNewAbortAndDurationchromestatus.comThe Media Source standard long ago changed to disallow ambiguously defined behavior involving asynchronous range removals: * SourceBuffer.abort() no longer aborts SourceBuffer.remove() operations * Setting MediaSource.duration can no longer truncate currently buffered media Exceptions will be thrown in both of these cases now. Safari and Firefox have long shipped this behavior, Chromium is the last browser remaining with the old behavior. Use counters show ~0.001%-0.005% of page loads hit the deprecated behavior. Primarily small Russian sites. If a site hits this issue, playback may now break. Usage of abort() cancelling removals is increasing, so it's prudent to resolve this deprecation before more incompatible usage appears.
▹ Multicol Column Wrapping
MulticolColumnWrappingchromestatus.comAdd support for the `column-wrap` and `column-height` CSS properties, from multicol Level 2. https://drafts.csswg.org/css-multicol-2/#cwr https://drafts.csswg.org/css-multicol-2/#ch This allows for vertical column layout, or even 2D column layout. Columns can have an explicit constrained height, apart from being derived from the content-box height of the multicol container, and wrap to a new row of columns when all columns have been filled for one row, rather than creating overflowing columns in the inline direction.
▹ Navigate Event Commit Behavior
NavigateEventCommitBehaviorchromestatus.comNormally, when navigateEvent.intercept() is called, the intercepted navigation commits (and therefore the URL updates) as soon as the NavigateEvent finishes dispatch. Adding a `precommitHandler` option to navigateEvent.intercept(), similar to `handler`, would defer the commit until that handler (and all other precommit handlers) are resolved, also allowing the handler to change the navigation's URL, info, status, and history handling behavior (push/replace).
▹ Navigation Id
NavigationIdchromestatus.comThis adds a Performance Timeline entry type, "back-forward-cache-restoration", which is emitted every time that a page is retrieved from the back-forward cache, and a field on all performance timeline entries, "navigationId", which can be used to tie performance events to the most recent navigation-like event. This allows developers to more easily use the performance APIs to compare the user experience of an SPA or a bfcache-eligible page with that of a traditional multi-page experience.
▹ Nested View Transition
NestedViewTransitionchromestatus.comAllow view-transitions to generate a nested pseudo-element tree rather than a flat one. This allows the view transition to appear more in line with its original elements and visual intent, as it enables clipping, nested 3D transforms, and proper application of effects like opacity, masking and filters.
▹ On Device Web Speech Available
OnDeviceWebSpeechAvailablechromestatus.comThis feature enables websites to support contextual biasing for speech recognition by adding a recognition phrase list to the Web Speech API. Developers can provide a list of phrases as well as updating them to apply a bias to the speech recognition models in favor of those phrases. This helps improve accuracy and relevance for domain-specific and personalized speech recognition.
▹ Paint Timing Mixin
PaintTimingMixinchromestatus.comExpose "paintTime" and "presentationTime" in event timing, element timing, LCP, long animation frames, paint timing. "paintTime" means the time when the rendering phase ended and the browser started the paint phase. "presentationTime" means the time when the "pixels reached the screen", which is somewhat implementation-defined
▹ Payment App
PaymentAppchromestatus.comThe API helps to develop new payment apps in web standard ways (e.g. service worker). If using them, payment app providers can provide simplified payment methods and user experiences.
▹ Payment Link Detection
PaymentLinkDetectionchromestatus.comAdds support for <link rel="facilitated-payment" href="..."> as a hint that the browser should notify registered payment clients about a pending push payment.
▹ Payment Request
PaymentRequestchromestatus.comTo help developers reduce friction in Payment Request flows, we are removing the user activation requirement. Spam and clickjacking mitigations are put in place to mitigate security and privacy risks with this change.
▹ Performance Navigation Timing Confidence
PerformanceNavigationTimingConfidencechromestatus.comWeb applications may suffer from bimodal distribution in page load performance, due to factors outside of the web application’s control. For example: * When a user agent first launches (a "cold start" scenario), it must perform many expensive initialization tasks that compete for resources on the system. * Browser extensions can affect the performance of a website. For instance, some extensions run additional code on every page you visit, which can increase CPU usage and result in slower response times. * When a machine is busy performing intensive tasks, it can lead to slower loading of web pages. In these scenarios, content the web app attempts to load will be in competition with other work happening on the system. This makes it difficult to detect if performance issues exist within web applications themselves, or because of external factors. Teams we have worked with have been surprised at the difference between real-world dashboard metrics and what they observe in page profiling tools. Without more information, it is challenging for developers to understand if (and when) their applications may be misbehaving or are simply being loaded in a contended period. A new ‘confidence’ field on the PerformanceNavigationTiming object will enable developers to discern if the navigation timings are representative for their web application.
▹ Permission Element
PermissionElementchromestatus.comProvide a new HTML element that interacts with the permission flow. The permission prompt is currently triggered directly from JS without the user agent having any strong signal of the user's intent. Having an in-content element that the user uses to trigger the permission flow allows for improved permission prompt UX for users as well as a recovery path from the "denied" permission state for sites. Explainer: https://github.com/WICG/PEPC/blob/main/explainer.md Instructions: https://github.com/WICG/PEPC/blob/main/HOWTO.md Developer facing documentation: https://developer.chrome.com/blog/permission-element-origin-trial
▹ Preferred Audio Output Devices
PreferredAudioOutputDeviceschromestatus.comThis feature adds setDefaultSinkId() to MediaDevices, which enables the top-level frame to change the default audio output device used by its subframes.
▹ Private Aggregation Api Error Reporting
PrivateAggregationApiErrorReportingchromestatus.comThere are a range of error conditions that can be hit when using the Private Aggregation API. For example, the privacy budget could run out, preventing any further histogram contributions. This feature allows developers to register histogram contributions that should only be sent if a particular type of error occurs. This feature supports measuring the frequency of the error conditions and to split these measurements on relevant developer-specified dimensions (e.g. version of deployed code). As the errors themselves may be cross-site information, we cannot simply expose them to the page for users without third-party cookies. Instead, this feature reuses the existing aggregate, noised reporting pipelines through the Aggregation Service.
▹ Private Network Access Null Ip Address
PrivateNetworkAccessNullIpAddresschromestatus.comWe propose to block access to IP address 0.0.0.0 in advance of PNA completely rolling out. Chrome is deprecating direct access to private network endpoints from public websites as part of the Private Network Access (PNA) specification (https://developer.chrome.com/blog/private-network-access-preflight/). Services listening on the localhost (127.0.0.0/8) are considered private according to the specification (https://wicg.github.io/private-network-access/#ip-address-space-heading). Chrome's PNA protection (rolled out as part of https://chromestatus.com/feature/5436853517811712) can be bypassed using the IP address 0.0.0.0 to access services listening on the localhost on macOS and Linux. This can also be abused in DNS rebinding attacks targeting a web application listening on the localhost. Since 0.0.0.0 is not used in practice (and should not be used), but was overlooked during https://chromestatus.com/feature/5436853517811712, we're deprecating it separately from the rest of the private network requests deprecation.
▹ Rel Opener Bcg Dependency Hint
RelOpenerBcgDependencyHintchromestatus.comExtends the use of the "opener" rel type to same-window navigations to signal to the browser that the destination page will open a new window and the referring page expects to be able to access it. Some user agents perform browsing context group changes on navigation that aren't strictly necessary for security in order to improve performance. This results in named window reuse not being possible across a back navigation. Annotating an anchor element with "opener" will signal to the user agent that performing a browsing context group change would break a future opener relationship.
▹ RTC Data Channel Priority
RTCDataChannelPrioritychromestatus.comMany applications have multiple media flows of the same data type and often some of the flows are more important than others. The priority setting can be used to indicate the relative priority of various flows. The priority API allows the JavaScript applications to tell the browser whether a particular media flow is high, medium, low or of very low importance to the application.
▹ RTC Encoded Frame Set Metadata
RTCEncodedFrameSetMetadatachromestatus.comAllow WebRTC Encoded Transform API to manipulate audio and video frame metadata. Some WebRTC Encoded Transform use cases involve manipulation of not only the payload of encoded video / audio frames but also its metadata. Some examples: * Altering the timestamp of a frame to introduce a delay, * Changing the mime type of the frame if the transform changes the type of the payload. * Forwarding of media to a new peer connection set up to use different metadata values Use cases: https://w3c.github.io/webrtc-nv-use-cases/#live-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#stored-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#auction Issue link: https://github.com/w3c/webrtc-nv-use-cases/issues/77
▹ RTC Rtp Script Transform
RTCRtpScriptTransformchromestatus.comThis API allows processing of encoded media flowing through an RTCPeerConnection. Chromium shipped an early version of this API in 2020. Since then, the spec has changed and other browsers have shipped the updated version of the spec (Safari in 2022 and Firefox in 2023). This launch refers to the latest spec version and is part of Interop 2025. This launch does not cover the generateKeyFrame method, which is still under discussion https://github.com/w3c/webrtc-encoded-transform/issues/143 https://github.com/w3c/webrtc-encoded-transform/issues/271 https://github.com/w3c/webrtc-encoded-transform/pull/269
▹ Scoped View Transitions
ScopedViewTransitionschromestatus.comExposes element.startViewTransition() on arbitrary HTML elements. The element establishes a scope for the transition, which means that the transition pseudo-elements are affected by ancestor clips and transforms, and multiple transitions on separate elements can run concurrently.
▹ Search Text Highlight Pseudo
SearchTextHighlightPseudochromestatus.comExposes find-in-page search result styling to authors as a highlight pseudo-element, like selection and spelling errors. This allows authors to change the foreground and background colors or add text decorations, which can be especially useful if the UA defaults have insufficient contrast with the page colors or are otherwise unsuitable.
▹ Shadow Root Reference Target
ShadowRootReferenceTargetchromestatus.comReference Target is a feature to enable using IDREF attributes such as `for` and `aria-labelledby` to refer to elements inside a component's shadow DOM, while maintaining encapsulation of the internal details of the shadow DOM. The main goal of this feature is to enable ARIA to work across shadow root boundaries. A component can specify an element in its shadow tree to act as its "reference target". When the host component is the target of a IDREF like a label's `for` attribute, the reference target becomes the effective target of the label. The shadow root specifies the ID of the target element inside the shadow DOM. This is done either in JavaScript with the `referenceTarget` attribute on the `ShadowRoot` object, or in HTML markup using the `shadowrootreferencetarget` attribute on the `<template>` element.
▹ Signature Based Integrity
SignatureBasedIntegritychromestatus.comThis feature provides web developers with a mechanism to verify the provenance of resources they depend upon, creating a technical foundation for trust in a site's dependencies. In short: servers can sign responses with a Ed25519 key pair, and web developers can require the user agent to verify the signature using a specific public key. This offers a helpful addition to URL-based checks offered by Content Security Policy on the one hand, and Subresource Integrity's content-based checks on the other.
▹ Soft Navigation Heuristics
SoftNavigationHeuristicschromestatus.comExposes the (experimental) soft navigation heuristics to web developers, using both PerformanceObserver and the performance timeline. This feature reports two new performance entries: - "soft-navigation", for user interactions which navigate the page. Defines a new timeOrigin to help slice the performance timeline. - "interaction-contentful-paint", which reports on the loading performance of interactions (beyond just next paint), used as LCP for soft-navigations.
▹ Text Detector
TextDetectorchromestatus.comThe Text Detection API is a subset of the Shape Detection API which provides the ability to detect and optionally transcribe text in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Tpcd
Tpcdchromestatus.comThis experiment exposes a temporary set of APIs which provide access to browser-determined treatment and control groups to support opt-in server side testing of the third-party cookie deprecation.
▹ Translation API
TranslationAPIchromestatus.comA JavaScript API to provide language translation capabilities to web pages. Browsers are increasingly offering language translation to their users. Such translation capabilities can also be useful to web developers. This is especially the case when browser's built-in translation abilities cannot help. An enterprise policy (GenAILocalFoundationalModelSettings) is available to disable the underlying model downloading which would render this API unavailable.
▹ Viewport Segments
ViewportSegmentschromestatus.comThe Viewport Segments API allows developers to adapt their website/webapp layout to target foldable devices. The viewport segments defines the position and dimensions of a logically separate region of the viewport. Viewport segments are created when the viewport is split by one or more hardware features (such as a fold or a hinge between separate displays) that act as a divider; segments are the regions of the viewport that can be treated as logically distinct by the author.
▹ Web App Installation
WebAppInstallationchromestatus.comThe Web Install API allows a web site to install a web app (same or cross domain). This functionality allows the creation of web based catalogues that can install PWAs directly from the web and into multiple platforms. https://aka.ms/webinstall
▹ Web App Scope Extensions
WebAppScopeExtensionschromestatus.comAdds a "scope_extensions" web app manifest field that enables web apps to extend their scope to other origins. Example usage: { "name": "Example", "display": "standalone", "start_url": "/index.html", "scope_extensions": [ {"type" : "origin", "origin" : "https://example.com"} ] } This allows sites that control multiple subdomains and top level domains to be presented as a single web app. Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file. { "https://sample-app.com/": { "scope": "/" } }
▹ Web Authentication Immediate Get
WebAuthenticationImmediateGetchromestatus.comA mediation mode for navigator.credentials.get() that causes browser sign-in UI to be displayed to the user if there is a passkey or password for the site that is immediately known to the browser, or else rejects the promise with NotAllowedError if there is no such credential available. This allows the site to avoid showing a sign-in page if the browser can offer a choice of sign-in credentials that are likely to succeed, while still allowing a traditional sign-in page flow for cases where there are no such credentials.
▹ Web Codecs Orientation
WebCodecsOrientationchromestatus.comIntroduces "rotation: int" and "flip: bool" values to various video related interfaces in WebCodecs so that developers can work with frame sources that have orientation (E.g., Android cameras, certain media). The VideoFrame interface grows the ability to create VideoFrames with arbitrary rotation and flip as well as accessors for this information on the VideoFrame object. The VideoDecoderConfig object gains rotation and flip fields that are emitted on decoded VideoFrame objects automatically. The VideoEncoder class gains mechanisms for passing rotation and flip information from encode() to the VideoDecoderConfig emitted as part of EncodedVideoChunkMetadata. If encode() is called with frames with different orientations a non-fatal exception will be thrown. configure() may be used to reset the allowed orientation.
▹ WebGPU Experimental Features
WebGPUExperimentalFeatureschromestatus.comFunctionality added to the WebGPU spec after its first shipment in a browser. ServiceWorker and SharedWorker support is added to WebGPU, aligning with existing WebGL capabilities.
▹ Web Identity Digital Credentials
WebIdentityDigitalCredentialschromestatus.comWebsites can and do get credentials from mobile wallet apps through a variety of mechanisms today (custom URL handlers, QR code scanning, etc.). This Web Platform feature would allow sites to request identity information from wallets via Android's IdentityCredential CredMan system. It is extensible to support multiple credential formats (eg. ISO mDoc and W3C verifiable credential) and allows multiple wallet apps to be used. Mechanisms are being added to help reduce the risk of ecosystem-scale abuse of real-world identity (see https://docs.google.com/document/u/1/d/1L68tmNXCQXucsCV8eS8CBd_F9FZ6TNwKNOaFkA8RfwI/edit).
▹ Web Preferences
WebPreferenceschromestatus.comThe Web Preference API aims to provide a way for sites to override the value for a given user preference (e.g. color-scheme preference) in a way that fully integrates with existing Web APIs.
▹ Web XR Depth Performance
WebXRDepthPerformancechromestatus.comExposes several new mechanisms to customize the behavior of the depth sensing feature within a WebXR session, with the goal of improving the performance of the generation or consumption of the depth buffer. The key mechanisms exposed are: the ability to request the raw or smooth depth buffer, the ability to request that the runtime stop or resume providing the depth buffer, and the ability to expose a depth buffer that does not align with the user's view exactly, so that the user agent does not need to perform unnecessary re-projections every frame.
▹ Web XR Layers
WebXRLayerschromestatus.comWebXR Layers offers a more efficient way of drawing immersive content. In addition to support for native color and depth textures and texture arrays, it also provides support for different layer types that are managed by the system compositor (as opposed to javascript).
▹ Web XR Spec Parity
WebXRSpecParitychromestatus.comUpdates our implementation of the WebXR specification to provide a few attributes that have been added over time. These are generally attributes that developers find useful or enable small performance improvements. These include but are not limited to: Setting/Querying the framerate on an XRSession (including supported framerates), Angular/Linear Velocities, Predicted Display Time of a Frame, isSystemKeyboardSupported, and XRWebGLLayer fixedFoveation

▹ Audio Context Playout Stats
AudioContextPlayoutStatschromestatus.comThe AudioContext.playoutStats API allows an application to measure the quality and latency of audio playout using WebAudio.
▹ Blocking Focus Without User Activation
BlockingFocusWithoutUserActivationchromestatus.comA permissions policy to restrict the use of programmatic focus, when not triggered by a user activation. The proposed policy provides a way to control access to the focus API without user activation. The immediate use case would be restricting all sandboxed frames. Focus API, in this context refers to focus management API and autofocus.
▹ Boundary Event Dispatch Tracks Node Removal
BoundaryEventDispatchTracksNodeRemovalchromestatus.comAfter an event target gets removed from the DOM, the logical target of the pointer as implied by the Pointer and Mouse boundary events (i.e. over, out, enter and leave events) should be the nearest ancestor still attached to the DOM. PEWG has recently reached consensus on this behavior, see https://github.com/web-platform-tests/interop/issues/380. Chrome has been keeping track of a node even after it gets removed from DOM. As a result, if the pointer moves to a new node B after the hit-test node A is removed from DOM, the boundary event sequence (pointerover, pointerout, pointerenter, pointerleave events and the corresponding mouse events) used to imply a pointer movement from A to B. As per the new consensus, the event sequence should imply a pointer movement from the "parent of A" to B.
▹ Canvas Floating Point
CanvasFloatingPointchromestatus.comIntroduce the the ability to use floating point pixel formats (as opposed to 8-bit fixed point) with CanvasRenderingContext2D, OffscreenCanvasRenderingContext2D, and ImageData. This is necessary for high precision applications (e.g, medical visualization), high dynamic range content, and linear working color spaces.
▹ Canvas Text Ng
CanvasTextNgchromestatus.comThis is not a web-exposed change. The implementation of CanvasRenderingContext2D's measureText(), fillText(), and strokeText() has a drastic change. This might affect performance, so we'd like to run an origin trial so canvas-heavy applications can try out the new implementation.
▹ Capability Delegation Display Capture Request
CapabilityDelegationDisplayCaptureRequestchromestatus.comThis feature is based on the general delegation mechanism (https://chromestatus.com/feature/5708770829139968) shipped on M100. Display-Capture Capability Delegation allows a Window to transfer the ability to call navigator.mediaDevices.getDisplayMedia() to another Window it trusts after relinquishing the transient user activation at the sender Window.
▹ Container Timing
ContainerTimingchromestatus.comThe Container Timing API enables monitoring when annotated sections of the DOM are displayed on screen and have finished their initial paint. A developer will have the ability to mark subsections of the DOM with the containertiming attribute (similar to elementtiming for the Element Timing API) and receive performance entries when that section has been painted for the first time. This API will allow developers to measure the timing of various components in their pages.
▹ Context Menu
ContextMenuchromestatus.comChange “click”, “contextmenu”, “auxclick” events to PointerEvent (instead of MouseEvent) to let developers: distinguish between mouse, pen and individual fingers in a multitouch interaction through pointerType and pointerId attributes, and utilize fractional event coordinates for high precision use cases.
▹ Controlled Frame
ControlledFramechromestatus.comAdds a Controlled Frame API available only to Isolated Web Apps (IWAs). This work adds a new Controlled Frame API which is only available to Isolated Web Apps (IWAs). Like similarly-named APIs on other platforms, Controlled Frame allows embedding all content, even third party content that can't be embedded in <iframe>. Controlled Frame also allows controlling embedded content with a collection of API methods and events. For more info on Isolated Web Apps, see the IWA explainer: https://github.com/WICG/isolated-web-apps/blob/main/README.md
▹ CSS Caret Animation
CSSCaretAnimationchromestatus.comChromium supports animation of the caret-color property, but when animated the default blinking behavior of the caret interferes with the animation. For instance, see the example at https://drafts.csswg.org/css-ui/#caret-animation where an animation from blue to red and back is rendered as a blinking cursor that is randomly blue or red. The CSS caret-animation property has two possible values: auto and manual, where auto means browser default (blinking) and manual means the page author is controlling the caret animation. In addition, via a user stylesheet, it allows users who are disturbed by or have adverse reactions to blinking or flashing visuals to disable the blinking.
▹ CSS Corner Shape
CSSCornerShapechromestatus.comEnable styling corners, on top of the existing border-radius, by expressing the shape/curvature of the corner as a superellipse. This allows shapes like squircles, notches, scoops etc., and animating between them.
▹ CSS Functions
CSSFunctionschromestatus.comCustom Functions are similar to custom properties, but instead of returning a single, fixed value, they return values based on other custom properties, parameters, and conditionals.
▹ CSS Inline If For Media Queries
CSSInlineIfForMediaQuerieschromestatus.comThe CSS if() function provides a concise way to express conditional values. It accepts a series of condition-value pairs, delimited by semicolons. The function evaluates each condition sequentially and returns the value associated with the first true condition. If none of the conditions evaluate to true, the function returns an empty token stream. This allows web authors to express complex conditional logic in a simple and concise way. Example: <style> div { color: var(--color); background-color: if(style(--color: white): black; else: white); } .dark { --color: black; } .light { --color: white; } </style> <div class="dark">dark</div> <div class="light">light</div>
▹ CSS Inline If For Style Queries
CSSInlineIfForStyleQuerieschromestatus.comThe CSS if() function provides a concise way to express conditional values. It accepts a series of condition-value pairs, delimited by semicolons. The function evaluates each condition sequentially and returns the value associated with the first true condition. If none of the conditions evaluate to true, the function returns an empty token stream. This allows web authors to express complex conditional logic in a simple and concise way. Example: <style> div { color: var(--color); background-color: if(style(--color: white): black; else: white); } .dark { --color: black; } .light { --color: white; } </style> <div class="dark">dark</div> <div class="light">light</div>
▹ CSS Inline If For Supports Queries
CSSInlineIfForSupportsQuerieschromestatus.comThe CSS if() function provides a concise way to express conditional values. It accepts a series of condition-value pairs, delimited by semicolons. The function evaluates each condition sequentially and returns the value associated with the first true condition. If none of the conditions evaluate to true, the function returns an empty token stream. This allows web authors to express complex conditional logic in a simple and concise way. Example: <style> div { color: var(--color); background-color: if(style(--color: white): black; else: white); } .dark { --color: black; } .light { --color: white; } </style> <div class="dark">dark</div> <div class="light">light</div>
▹ CSS Preferred Text Scale
CSSPreferredTextScalechromestatus.comExposes a user's preferred font scale to CSS. Currently, it is not practical for a page to detect if the user has changed their preferred font size via the Operating System's preferences. This CSS environment variable will reflect the scale chosen by the user.
▹ CSS Progress Notation
CSSProgressNotationchromestatus.comThe progress() functional notation returns a <number> value representing the position of one calculation (the progress value) between two other calculations (the progress start value and progress end value). progress() is a math function. The syntax of progress() is defined as follows: <progress()> = progress(<calc-sum>, <calc-sum>, <calc-sum>) where the first, second, and third <calc-sum> values represent the progress value, progress start value, and progress end value, respectively.
▹ CSS Reading Flow
CSSReadingFlowchromestatus.comThe reading-flow CSS property controls the order in which elements in a flex, grid or block layout are exposed to accessibility tools and focused via TAB keyboard focus navigation. This change implements the CSS reading-flow keyword values: * normal * flex-visual * flex-flow * grid-rows * grid-columns * grid-order * source-order See spec: https://drafts.csswg.org/css-display-4/#reading-flow The reading-order CSS property allows authors to manually-override the order within a reading flow container. It is an integer with default value 0. See spec: https://drafts.csswg.org/css-display-4/#reading-order Please find more thorough examples of how TAB keyboard navigation and accessibility is improved by this feature here: https://chrome.dev/reading-flow-examples/
▹ CSS Sibling Functions
CSSSiblingFunctionschromestatus.comsibling-index() and sibling-count() can be used as integers in CSS property values to style elements based on their position among its siblings, or the total number of siblings respectively. These functions can be used directly as integer values, but more interestingly inside calc() expressions. Example: li { margin-left: calc(10px * sibling-index()); }
▹ CSS Sign Related Functions
CSSSignRelatedFunctionschromestatus.comThe sign-related functions abs() and sign() compute various functions related to the sign of their argument. The abs(A) function contains one calculation A, and returns the absolute value of A, as the same type as the input: if A’s numeric value is positive or 0⁺, just A again; otherwise -1 * A. The sign(A) function contains one calculation A, and returns -1 if A’s numeric value is negative, +1 if A’s numeric value is positive, 0⁺ if A’s numeric value is 0⁺, and 0⁻ if A’s numeric value is 0⁻. The return type is a <number>, made consistent with the input calculation’s type.
▹ CSS System Accent Color
CSSSystemAccentColorchromestatus.comThis feature empowers web developers to enhance the visual appeal of their websites by leveraging the operating system's accent color for form elements. By utilizing the "accent-color" CSS property, developers can ensure that form elements such as checkboxes, radio buttons, and progress bars automatically adopt the accent color defined by the user's operating system. This feature is an enhancement to existing feature that is already shipped in Chromium: https://groups.google.com/a/chromium.org/g/blink-dev/c/WwYkLjbGhoA
▹ CSS Text Auto Space
CSSTextAutoSpacechromestatus.comInserts small spacings to match the established typographic rules automatically. The spec currently defines one rule for Han ideographic characters and one for French. The initial implementation focuses on the Han ideographic characters rule. Text written in Han ideographic writing systems often mixes multiple scripts, usually the Han ideographic scripts, Latin scripts, and ASCII digits. Small spacings when switching from and to non-Han ideographic scripts often help the readability. This property lets browsers insert such spacings automatically. This property has several values, including values for other writing systems. The initial implementation supports `normal` and `no-autospace`. The initial value is set to `no-autospace` to start conservatively and be more careful for the site compatibilities. Authors can add `text-autospace: normal` to enable the feature.
▹ CSS View Transition Auto Name
CSSViewTransitionAutoNamechromestatus.comContact emails vmpstr@chromium.org, nrosenthal@chromium.org Explainer None Specification https://drafts.csswg.org/css-view-transitions-2/#auto-vt-name Summary 'auto' uses the element's id attribute to generate a unique match for view transition cases. In absence of the id, it generates a unique id based on the element's identity and remains the same for this element. This is used in Single Page App or Multi Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ CSS View Transition Match Element
CSSViewTransitionMatchElementchromestatus.com'match-element' generates a unique id based on the element's identity and renames the same for this element. This is used in Single Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ Device Orientation Request Permission
DeviceOrientationRequestPermissionchromestatus.comAllows developers to ask for permission to use the Device Orientation and Device Motion APIs. Access to these APIs is currently granted by default, and these new functions are part of the long-term plan to require requesting permission before using window.ondevicemotion and window.ondeviceorientation.
▹ Dialog New Focus Behavior
DialogNewFocusBehaviorchromestatus.comSome changes are being made to which element is selected to get focus when a dialog element is opened: 1. Make the dialog focusing steps look at keyboard focusable elements instead of any focusable element. 2. Make the dialog element itself get focus if it has the autofocus attribute set. 3. Make the dialog element itself get focus as a fallback instead of focus being "reset" to the body element.
▹ Document Isolation Policy
DocumentIsolationPolicychromestatus.comDocument-Isolation-Policy allows a document to enable crossOriginIsolation for itself, without having to deploy COOP or COEP, and regardless of the crossOriginIsolation status of the page. The policy is backed by process isolation. Additionally, the document non-CORS cross-origin subresources will either be loaded without credentials or will need to have a CORP header.
▹ Document Policy Include JS Call Stacks In Crash Reports
DocumentPolicyIncludeJSCallStacksInCrashReportschromestatus.comThis feature captures the JS call stack when a web page becomes unresponsive due to JavaScript code running an infinite loop or other very long computation. This helps developers to identify the cause of the unresponsiveness and fix it more easily. The JS call stack is included in the crash reporting API when the reason is unresponsive.
▹ Escape Lt Gt In Attributes
EscapeLtGtInAttributeschromestatus.comEscape "<" and ">" in values of attributes on serialization. This mitigates the risk of mutation XSS attacks, which occur when value of an attribute is interpreted as a start tag token after being serialized and re-parsed.
▹ Extended Text Metrics
ExtendedTextMetricschromestatus.comExpand the TextMetrics Canvas API to support selection rectangles, bounding box queries, and grapheme cluster-based operations. This new functionality should enable complex text editing applications with accurate selection, caret positioning, and hit testing. Additionally, cluster-based rendering facilitates sophisticated text effects such as independent character animations and styling.
▹ Face Detector
FaceDetectorchromestatus.comThe Face Detection API is a subset of the Shape Detection API which provides the ability to detect human faces and facial landmarks in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ File System Access API Experimental
FileSystemAccessAPIExperimentalchromestatus.comCurrently, the File System Access API does not support an efficient way to move or rename files or directories. This requires creating a new file/directory, copying over data (recursively, in the case of a directory), and removing the original. This process is slow, error prone (e.g. disk full), and can require re-uploading files in some cases. See https://github.com/WICG/file-system-access/pull/317
▹ Focusgroup
Focusgroupchromestatus.comThe Focusgroup feature will facilitate keyboard focus navigation using the keyboard arrow keys among a set of focusable elements.
▹ Gamepad Multitouch
GamepadMultitouchchromestatus.comExtend the Gamepad API to support multitouch surfaces (touchpads). Providing a touchpad API eases application implementation and provides greater functionality browser interoperability.
▹ Heading Offset
HeadingOffsetchromestatus.comA system for creating structured headings within a document. The `headingoffset=` attribute can be added to elements that influences the child `h1`-`h6` elements' heading levels, for example a `headingoffset=1` will mean all `h1` elements will have an effective heading level of 2, and so on. In addition the `:heading` pseudo class will select all headings (tags of `h1` to `h6`) and the `:heading(N)` pseudo class will select headings with an _effective_ level of `N`. This allows for documents with different heading structures (for example user generated content) to be combined to create a well defined heading structure without significantly altering the underlying documents.
▹ HTML Command Request Close
HTMLCommandRequestClosechromestatus.comDialog elements can be closed through a variety of mechanisms, sometimes developers want to have the ability to prevent closure. To achieve this dialogs fire a cancel event. Originally this was only fired via a close request (e.g. ESC key press), recently a `requestClose()` JS function was added which also fires the cancel event. The 'request-close' command brings that new ability to the declarative invoker commands API.
▹ Indexed Db Get All Records
IndexedDbGetAllRecordschromestatus.comThis feature adds the getAllRecords() API to IndexedDB's IDBObjectStore and IDBIndex. It also adds a direction parameter to getAll() and getAllKeys(). This functionality enables certain read patterns to be significantly faster when compared to the existing alternative of iteration with cursors. One key workload from a Microsoft property showed a 350ms improvement. getAllRecords() effectively combines getAllKeys() and getAll() by enumerating both primary keys and values at the same time. For an IDBIndex, getAllRecords() also provides the record's index key in addition to the primary key and value. getAllRecords() can optionally return records in either ascending or descending order. This option is also back-ported to the existing operations getAll() and getAllKeys().
▹ Install On Device Speech Recognition
InstallOnDeviceSpeechRecognitionchromestatus.comThis feature adds on-device speech recognition support to the Web Speech API, allowing websites to ensure that neither audio nor transcribed speech are sent to a third-party service for processing. Websites can query the availability of on-device speech recognition for specific languages, prompt users to install the necessary resources for on-device speech recognition, and choose between on-device or cloud-based speech recognition as needed.
▹ Inverted Colors
InvertedColorschromestatus.comAdds the `inverted-colors` media feature, an indication that the user agent or underlying operating system has forcibly inverted all colors, not a request to do so. This is sometimes provided as a simple accessibility feature, allowing users to switch between light-on-dark and dark-on-light text. Valid options are 'inverted' or 'none'.
▹ Language Detection API
LanguageDetectionAPIchromestatus.comA JavaScript API for detecting the language of text, with confidence levels. An important supplement to translation is language detection. This can be combined with translation, e.g. taking user input in an unknown language and translating it to a specific target language. Browsers today often already have langauge detection capabilities, and we want to offer them to web developers through a JavaScript API, supplementing the translation API. An enterprise policy (GenAILocalFoundationalModelSettings) is available to disable the underlying model downloading which would render this API unavailable.
▹ Layout Stretch
LayoutStretchchromestatus.comA keyword for CSS sizing properties (e.g. 'width', 'height') that allows elements to grow to exactly fill their containing block's available space. It is similar to '100%', except the resulting size is applied to the element's margin box instead of the box indicated by 'box-sizing'. Using this keyword allows the element to keep its margins while still being as large as possible. An unprefixed version of '-webkit-fill-available'.
▹ Media Capture Background Blur
MediaCaptureBackgroundBlurchromestatus.comThe Background Blur API allows web developers to use the native platform's API for camera background segmentation. As Background Blur has become one of the most used features on video conferencing apps like Teams, Meet, Zoom, and Webex, we want web apps to leverage the same platform APIs without completely relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud based solutions.
▹ Media Capture Voice Isolation
MediaCaptureVoiceIsolationchromestatus.comThis is about adding support in Chrome for the VoiceIsolation getUserMedia constraint (https://w3c.github.io/mediacapture-extensions/#voiceisolation-constraint). The constraint only takes effect on platforms where there is low-level support for voice-isolation style denoising. Currently this is limited to a selected number of ChromeOS devices, but further platforms will be added.
▹ Media Source Extensions For Web Codecs
MediaSourceExtensionsForWebCodecschromestatus.comExtends the Media Source Extensions API (MSE) to enable buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.
▹ Media Source New Abort And Duration
MediaSourceNewAbortAndDurationchromestatus.comThe Media Source standard long ago changed to disallow ambiguously defined behavior involving asynchronous range removals: * SourceBuffer.abort() no longer aborts SourceBuffer.remove() operations * Setting MediaSource.duration can no longer truncate currently buffered media Exceptions will be thrown in both of these cases now. Safari and Firefox have long shipped this behavior, Chromium is the last browser remaining with the old behavior. Use counters show ~0.001%-0.005% of page loads hit the deprecated behavior. Primarily small Russian sites. If a site hits this issue, playback may now break. Usage of abort() cancelling removals is increasing, so it's prudent to resolve this deprecation before more incompatible usage appears.
▹ Multicol Column Wrapping
MulticolColumnWrappingchromestatus.comAdd support for the `column-wrap` and `column-height` CSS properties, from multicol Level 2. https://drafts.csswg.org/css-multicol-2/#cwr https://drafts.csswg.org/css-multicol-2/#ch This allows for vertical column layout, or even 2D column layout. Columns can have an explicit constrained height, apart from being derived from the content-box height of the multicol container, and wrap to a new row of columns when all columns have been filled for one row, rather than creating overflowing columns in the inline direction.
▹ Navigate Event Commit Behavior
NavigateEventCommitBehaviorchromestatus.comNormally, when navigateEvent.intercept() is called, the intercepted navigation commits (and therefore the URL updates) as soon as the NavigateEvent finishes dispatch. Adding a `precommitHandler` option to navigateEvent.intercept(), similar to `handler`, would defer the commit until that handler (and all other precommit handlers) are resolved, also allowing the handler to change the navigation's URL, info, status, and history handling behavior (push/replace).
▹ Navigation Id
NavigationIdchromestatus.comThis adds a Performance Timeline entry type, "back-forward-cache-restoration", which is emitted every time that a page is retrieved from the back-forward cache, and a field on all performance timeline entries, "navigationId", which can be used to tie performance events to the most recent navigation-like event. This allows developers to more easily use the performance APIs to compare the user experience of an SPA or a bfcache-eligible page with that of a traditional multi-page experience.
▹ Nested View Transition
NestedViewTransitionchromestatus.comAllow view-transitions to generate a nested pseudo-element tree rather than a flat one. This allows the view transition to appear more in line with its original elements and visual intent, as it enables clipping, nested 3D transforms, and proper application of effects like opacity, masking and filters.
▹ On Device Web Speech Available
OnDeviceWebSpeechAvailablechromestatus.comThis feature enables websites to support contextual biasing for speech recognition by adding a recognition phrase list to the Web Speech API. Developers can provide a list of phrases as well as updating them to apply a bias to the speech recognition models in favor of those phrases. This helps improve accuracy and relevance for domain-specific and personalized speech recognition.
▹ Paint Timing Mixin
PaintTimingMixinchromestatus.comExpose "paintTime" and "presentationTime" in event timing, element timing, LCP, long animation frames, paint timing. "paintTime" means the time when the rendering phase ended and the browser started the paint phase. "presentationTime" means the time when the "pixels reached the screen", which is somewhat implementation-defined
▹ Payment App
PaymentAppchromestatus.comThe API helps to develop new payment apps in web standard ways (e.g. service worker). If using them, payment app providers can provide simplified payment methods and user experiences.
▹ Payment Link Detection
PaymentLinkDetectionchromestatus.comAdds support for <link rel="facilitated-payment" href="..."> as a hint that the browser should notify registered payment clients about a pending push payment.
▹ Payment Request
PaymentRequestchromestatus.comTo help developers reduce friction in Payment Request flows, we are removing the user activation requirement. Spam and clickjacking mitigations are put in place to mitigate security and privacy risks with this change.
▹ Performance Navigation Timing Confidence
PerformanceNavigationTimingConfidencechromestatus.comWeb applications may suffer from bimodal distribution in page load performance, due to factors outside of the web application’s control. For example: * When a user agent first launches (a "cold start" scenario), it must perform many expensive initialization tasks that compete for resources on the system. * Browser extensions can affect the performance of a website. For instance, some extensions run additional code on every page you visit, which can increase CPU usage and result in slower response times. * When a machine is busy performing intensive tasks, it can lead to slower loading of web pages. In these scenarios, content the web app attempts to load will be in competition with other work happening on the system. This makes it difficult to detect if performance issues exist within web applications themselves, or because of external factors. Teams we have worked with have been surprised at the difference between real-world dashboard metrics and what they observe in page profiling tools. Without more information, it is challenging for developers to understand if (and when) their applications may be misbehaving or are simply being loaded in a contended period. A new ‘confidence’ field on the PerformanceNavigationTiming object will enable developers to discern if the navigation timings are representative for their web application.
▹ Permission Element
PermissionElementchromestatus.comProvide a new HTML element that interacts with the permission flow. The permission prompt is currently triggered directly from JS without the user agent having any strong signal of the user's intent. Having an in-content element that the user uses to trigger the permission flow allows for improved permission prompt UX for users as well as a recovery path from the "denied" permission state for sites. Explainer: https://github.com/WICG/PEPC/blob/main/explainer.md Instructions: https://github.com/WICG/PEPC/blob/main/HOWTO.md Developer facing documentation: https://developer.chrome.com/blog/permission-element-origin-trial
▹ Preferred Audio Output Devices
PreferredAudioOutputDeviceschromestatus.comThis feature adds setDefaultSinkId() to MediaDevices, which enables the top-level frame to change the default audio output device used by its subframes.
▹ Private Aggregation Api Error Reporting
PrivateAggregationApiErrorReportingchromestatus.comThere are a range of error conditions that can be hit when using the Private Aggregation API. For example, the privacy budget could run out, preventing any further histogram contributions. This feature allows developers to register histogram contributions that should only be sent if a particular type of error occurs. This feature supports measuring the frequency of the error conditions and to split these measurements on relevant developer-specified dimensions (e.g. version of deployed code). As the errors themselves may be cross-site information, we cannot simply expose them to the page for users without third-party cookies. Instead, this feature reuses the existing aggregate, noised reporting pipelines through the Aggregation Service.
▹ Private Network Access Null Ip Address
PrivateNetworkAccessNullIpAddresschromestatus.comWe propose to block access to IP address 0.0.0.0 in advance of PNA completely rolling out. Chrome is deprecating direct access to private network endpoints from public websites as part of the Private Network Access (PNA) specification (https://developer.chrome.com/blog/private-network-access-preflight/). Services listening on the localhost (127.0.0.0/8) are considered private according to the specification (https://wicg.github.io/private-network-access/#ip-address-space-heading). Chrome's PNA protection (rolled out as part of https://chromestatus.com/feature/5436853517811712) can be bypassed using the IP address 0.0.0.0 to access services listening on the localhost on macOS and Linux. This can also be abused in DNS rebinding attacks targeting a web application listening on the localhost. Since 0.0.0.0 is not used in practice (and should not be used), but was overlooked during https://chromestatus.com/feature/5436853517811712, we're deprecating it separately from the rest of the private network requests deprecation.
▹ Rel Opener Bcg Dependency Hint
RelOpenerBcgDependencyHintchromestatus.comExtends the use of the "opener" rel type to same-window navigations to signal to the browser that the destination page will open a new window and the referring page expects to be able to access it. Some user agents perform browsing context group changes on navigation that aren't strictly necessary for security in order to improve performance. This results in named window reuse not being possible across a back navigation. Annotating an anchor element with "opener" will signal to the user agent that performing a browsing context group change would break a future opener relationship.
▹ RTC Data Channel Priority
RTCDataChannelPrioritychromestatus.comMany applications have multiple media flows of the same data type and often some of the flows are more important than others. The priority setting can be used to indicate the relative priority of various flows. The priority API allows the JavaScript applications to tell the browser whether a particular media flow is high, medium, low or of very low importance to the application.
▹ RTC Encoded Frame Set Metadata
RTCEncodedFrameSetMetadatachromestatus.comAllow WebRTC Encoded Transform API to manipulate audio and video frame metadata. Some WebRTC Encoded Transform use cases involve manipulation of not only the payload of encoded video / audio frames but also its metadata. Some examples: * Altering the timestamp of a frame to introduce a delay, * Changing the mime type of the frame if the transform changes the type of the payload. * Forwarding of media to a new peer connection set up to use different metadata values Use cases: https://w3c.github.io/webrtc-nv-use-cases/#live-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#stored-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#auction Issue link: https://github.com/w3c/webrtc-nv-use-cases/issues/77
▹ RTC Rtp Script Transform
RTCRtpScriptTransformchromestatus.comThis API allows processing of encoded media flowing through an RTCPeerConnection. Chromium shipped an early version of this API in 2020. Since then, the spec has changed and other browsers have shipped the updated version of the spec (Safari in 2022 and Firefox in 2023). This launch refers to the latest spec version and is part of Interop 2025. This launch does not cover the generateKeyFrame method, which is still under discussion https://github.com/w3c/webrtc-encoded-transform/issues/143 https://github.com/w3c/webrtc-encoded-transform/issues/271 https://github.com/w3c/webrtc-encoded-transform/pull/269
▹ Scoped View Transitions
ScopedViewTransitionschromestatus.comExposes element.startViewTransition() on arbitrary HTML elements. The element establishes a scope for the transition, which means that the transition pseudo-elements are affected by ancestor clips and transforms, and multiple transitions on separate elements can run concurrently.
▹ Search Text Highlight Pseudo
SearchTextHighlightPseudochromestatus.comExposes find-in-page search result styling to authors as a highlight pseudo-element, like selection and spelling errors. This allows authors to change the foreground and background colors or add text decorations, which can be especially useful if the UA defaults have insufficient contrast with the page colors or are otherwise unsuitable.
▹ Selection Across Shadow DOM
SelectionAcrossShadowDOMchromestatus.comThis feature ships two new API methods for the Selection API: * Selection.direction which returns the selection's direction as either "none", "forward" or "backward" * Selection.getComposedRanges() which returns a list of 0 or 1 “composed” StaticRange A “composed” StaticRange is allowed to cross shadow boundaries, which normal Ranges cannot. For example: const range = getSelection().getComposedRanges({ shadowRoots: [root] }); If the selection crosses a shadow root boundary that isn’t provided in the shadowRots list, then the StaticRange's endpoints will be “rescoped” to be outside that tree. This makes sure we do not expose unknown shadow trees.
▹ Shadow Root Reference Target
ShadowRootReferenceTargetchromestatus.comReference Target is a feature to enable using IDREF attributes such as `for` and `aria-labelledby` to refer to elements inside a component's shadow DOM, while maintaining encapsulation of the internal details of the shadow DOM. The main goal of this feature is to enable ARIA to work across shadow root boundaries. A component can specify an element in its shadow tree to act as its "reference target". When the host component is the target of a IDREF like a label's `for` attribute, the reference target becomes the effective target of the label. The shadow root specifies the ID of the target element inside the shadow DOM. This is done either in JavaScript with the `referenceTarget` attribute on the `ShadowRoot` object, or in HTML markup using the `shadowrootreferencetarget` attribute on the `<template>` element.
▹ Signature Based Integrity
SignatureBasedIntegritychromestatus.comThis feature provides web developers with a mechanism to verify the provenance of resources they depend upon, creating a technical foundation for trust in a site's dependencies. In short: servers can sign responses with a Ed25519 key pair, and web developers can require the user agent to verify the signature using a specific public key. This offers a helpful addition to URL-based checks offered by Content Security Policy on the one hand, and Subresource Integrity's content-based checks on the other.
▹ Soft Navigation Heuristics
SoftNavigationHeuristicschromestatus.comExposes the (experimental) soft navigation heuristics to web developers, using both PerformanceObserver and the performance timeline. This feature reports two new performance entries: - "soft-navigation", for user interactions which navigate the page. Defines a new timeOrigin to help slice the performance timeline. - "interaction-contentful-paint", which reports on the loading performance of interactions (beyond just next paint), used as LCP for soft-navigations.
▹ Text Detector
TextDetectorchromestatus.comThe Text Detection API is a subset of the Shape Detection API which provides the ability to detect and optionally transcribe text in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Tpcd
Tpcdchromestatus.comThis experiment exposes a temporary set of APIs which provide access to browser-determined treatment and control groups to support opt-in server side testing of the third-party cookie deprecation.
▹ Viewport Segments
ViewportSegmentschromestatus.comThe Viewport Segments API allows developers to adapt their website/webapp layout to target foldable devices. The viewport segments defines the position and dimensions of a logically separate region of the viewport. Viewport segments are created when the viewport is split by one or more hardware features (such as a fold or a hinge between separate displays) that act as a divider; segments are the regions of the viewport that can be treated as logically distinct by the author.
▹ Web App Installation
WebAppInstallationchromestatus.comThe Web Install API allows a web site to install a web app (same or cross domain). This functionality allows the creation of web based catalogues that can install PWAs directly from the web and into multiple platforms. https://aka.ms/webinstall
▹ Web App Scope Extensions
WebAppScopeExtensionschromestatus.comAdds a "scope_extensions" web app manifest field that enables web apps to extend their scope to other origins. Example usage: { "name": "Example", "display": "standalone", "start_url": "/index.html", "scope_extensions": [ {"type" : "origin", "origin" : "https://example.com"} ] } This allows sites that control multiple subdomains and top level domains to be presented as a single web app. Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file. { "https://sample-app.com/": { "scope": "/" } }
▹ Web Authentication Align Error Type For Payment Credential Create
WebAuthenticationAlignErrorTypeForPaymentCredentialCreatechromestatus.comCorrect the error type thrown during WebAuthn credential creation for 'payment' credentials. Due to a historic specification mismatch, creating a 'payment' credential in a cross-origin iframe without a user activation would throw a SecurityError instead of a NotAllowedError, which is what is thrown for non-payment credentials. This is a breaking change, albeit a niche one. Code that previously detected the type of error thrown (e.g., `e instanceof SecurityError`) would be affected. Code that just generally handles errors during credential creation (e.g. `catch (e)`) will continue to function correctly.
▹ Web Authentication Immediate Get
WebAuthenticationImmediateGetchromestatus.comA mediation mode for navigator.credentials.get() that causes browser sign-in UI to be displayed to the user if there is a passkey or password for the site that is immediately known to the browser, or else rejects the promise with NotAllowedError if there is no such credential available. This allows the site to avoid showing a sign-in page if the browser can offer a choice of sign-in credentials that are likely to succeed, while still allowing a traditional sign-in page flow for cases where there are no such credentials.
▹ Web Codecs Orientation
WebCodecsOrientationchromestatus.comIntroduces "rotation: int" and "flip: bool" values to various video related interfaces in WebCodecs so that developers can work with frame sources that have orientation (E.g., Android cameras, certain media). The VideoFrame interface grows the ability to create VideoFrames with arbitrary rotation and flip as well as accessors for this information on the VideoFrame object. The VideoDecoderConfig object gains rotation and flip fields that are emitted on decoded VideoFrame objects automatically. The VideoEncoder class gains mechanisms for passing rotation and flip information from encode() to the VideoDecoderConfig emitted as part of EncodedVideoChunkMetadata. If encode() is called with frames with different orientations a non-fatal exception will be thrown. configure() may be used to reset the allowed orientation.
▹ Web Crypto Ed25519
WebCryptoEd25519chromestatus.comThis feature adds support for Curve25519 algorithms in the Web Cryptography API, namely the signature algorithm Ed25519
▹ WebGPU Experimental Features
WebGPUExperimentalFeatureschromestatus.comFunctionality added to the WebGPU spec after its first shipment in a browser. ServiceWorker and SharedWorker support is added to WebGPU, aligning with existing WebGL capabilities.
▹ Web Identity Digital Credentials
WebIdentityDigitalCredentialschromestatus.comWebsites can and do get credentials from mobile wallet apps through a variety of mechanisms today (custom URL handlers, QR code scanning, etc.). This Web Platform feature would allow sites to request identity information from wallets via Android's IdentityCredential CredMan system. It is extensible to support multiple credential formats (eg. ISO mDoc and W3C verifiable credential) and allows multiple wallet apps to be used. Mechanisms are being added to help reduce the risk of ecosystem-scale abuse of real-world identity (see https://docs.google.com/document/u/1/d/1L68tmNXCQXucsCV8eS8CBd_F9FZ6TNwKNOaFkA8RfwI/edit).
▹ Web Preferences
WebPreferenceschromestatus.comThe Web Preference API aims to provide a way for sites to override the value for a given user preference (e.g. color-scheme preference) in a way that fully integrates with existing Web APIs.
▹ Web XR Layers
WebXRLayerschromestatus.comWebXR Layers offers a more efficient way of drawing immersive content. In addition to support for native color and depth textures and texture arrays, it also provides support for different layer types that are managed by the system compositor (as opposed to javascript).
▹ Web XR Spec Parity
WebXRSpecParitychromestatus.comUpdates our implementation of the WebXR specification to provide a few attributes that have been added over time. These are generally attributes that developers find useful or enable small performance improvements. These include but are not limited to: Setting/Querying the framerate on an XRSession (including supported framerates), Angular/Linear Velocities, Predicted Display Time of a Frame, isSystemKeyboardSupported, and XRWebGLLayer fixedFoveation

Chromium 135
▹ Audio Context Playout Stats
AudioContextPlayoutStatschromestatus.comThe AudioContext.playoutStats API allows an application to measure the quality and latency of audio playout using WebAudio.
▹ Blocking Focus Without User Activation
BlockingFocusWithoutUserActivationchromestatus.comA permissions policy to restrict the use of programmatic focus, when not triggered by a user activation. The proposed policy provides a way to control access to the focus API without user activation. The immediate use case would be restricting all sandboxed frames. Focus API, in this context refers to focus management API and autofocus.
▹ Boundary Event Dispatch Tracks Node Removal
BoundaryEventDispatchTracksNodeRemovalchromestatus.comAfter an event target gets removed from the DOM, the logical target of the pointer as implied by the Pointer and Mouse boundary events (i.e. over, out, enter and leave events) should be the nearest ancestor still attached to the DOM. PEWG has recently reached consensus on this behavior, see https://github.com/web-platform-tests/interop/issues/380. Chrome has been keeping track of a node even after it gets removed from DOM. As a result, if the pointer moves to a new node B after the hit-test node A is removed from DOM, the boundary event sequence (pointerover, pointerout, pointerenter, pointerleave events and the corresponding mouse events) used to imply a pointer movement from A to B. As per the new consensus, the event sequence should imply a pointer movement from the "parent of A" to B.
▹ Canvas Floating Point
CanvasFloatingPointchromestatus.comIntroduce the the ability to use floating point pixel formats (as opposed to 8-bit fixed point) with CanvasRenderingContext2D, OffscreenCanvasRenderingContext2D, and ImageData. This is necessary for high precision applications (e.g, medical visualization), high dynamic range content, and linear working color spaces.
▹ Canvas Text Lang
CanvasTextLangchromestatus.comThe <canvas> DOM element, like all DOM elements, accepts a `lang` attribute that is used to define language specific treatment for font selection (when fonts have locale specific glyphs). Browsers respect this attribute. However, when an OffscreenCanvas is created there is no way to set locale information, possibly resulting in a state where an offscreen canvas produces rendered results that differ from the canvas in which it's output is used. This feature adds a `lang` IDL attribute to CanvasTextDrawingStyles to give developers direct control over the language for the text drawing and metrics.
▹ Capability Delegation Display Capture Request
CapabilityDelegationDisplayCaptureRequestchromestatus.comThis feature is based on the general delegation mechanism (https://chromestatus.com/feature/5708770829139968) shipped on M100. Display-Capture Capability Delegation allows a Window to transfer the ability to call navigator.mediaDevices.getDisplayMedia() to another Window it trusts after relinquishing the transient user activation at the sender Window.
▹ Click To Captured Pointer
ClickToCapturedPointerchromestatus.comIf a pointer is captured while the `pointerup` event is being dispatched, the `click` event will be dispatched to the captured target instead of the nearest common ancestor of `pointerdown` and `pointerup` events as per the UI Event spec. For uncaptured pointers, the `click` target remains unchanged.
▹ Container Timing
ContainerTimingchromestatus.comThe Container Timing API enables monitoring when annotated sections of the DOM are displayed on screen and have finished their initial paint. A developer will have the ability to mark subsections of the DOM with the containertiming attribute (similar to elementtiming for the Element Timing API) and receive performance entries when that section has been painted for the first time. This API will allow developers to measure the timing of various components in their pages.
▹ Context Menu
ContextMenuchromestatus.comChange “click”, “contextmenu”, “auxclick” events to PointerEvent (instead of MouseEvent) to let developers: distinguish between mouse, pen and individual fingers in a multitouch interaction through pointerType and pointerId attributes, and utilize fractional event coordinates for high precision use cases.
▹ Controlled Frame
ControlledFramechromestatus.comAdds a Controlled Frame API available only to Isolated Web Apps (IWAs). This work adds a new Controlled Frame API which is only available to Isolated Web Apps (IWAs). Like similarly-named APIs on other platforms, Controlled Frame allows embedding all content, even third party content that can't be embedded in <iframe>. Controlled Frame also allows controlling embedded content with a collection of API methods and events. For more info on Isolated Web Apps, see the IWA explainer: https://github.com/WICG/isolated-web-apps/blob/main/README.md
▹ CSS Caret Animation
CSSCaretAnimationchromestatus.comChromium supports animation of the caret-color property, but when animated the default blinking behavior of the caret interferes with the animation. For instance, see the example at https://drafts.csswg.org/css-ui/#caret-animation where an animation from blue to red and back is rendered as a blinking cursor that is randomly blue or red. The CSS caret-animation property has two possible values: auto and manual, where auto means browser default (blinking) and manual means the page author is controlling the caret animation. In addition, via a user stylesheet, it allows users who are disturbed by or have adverse reactions to blinking or flashing visuals to disable the blinking.
▹ CSS Corner Shape
CSSCornerShapechromestatus.comEnable styling corners, on top of the existing border-radius, by expressing the shape/curvature of the corner as a superellipse. This allows shapes like squircles, notches, scoops etc., and animating between them.
▹ CSS Dynamic Range Limit
CSSDynamicRangeLimitchromestatus.comEnables a page to limit the maximum brightness of HDR content.
▹ CSS Functions
CSSFunctionschromestatus.comCustom Functions are similar to custom properties, but instead of returning a single, fixed value, they return values based on other custom properties, parameters, and conditionals.
▹ CSS Inline If For Media Queries
CSSInlineIfForMediaQuerieschromestatus.comThe CSS if() function provides a concise way to express conditional values. It accepts a series of condition-value pairs, delimited by semicolons. The function evaluates each condition sequentially and returns the value associated with the first true condition. If none of the conditions evaluate to true, the function returns an empty token stream. This allows web authors to express complex conditional logic in a simple and concise way. Example: <style> div { color: var(--color); background-color: if(style(--color: white): black; else: white); } .dark { --color: black; } .light { --color: white; } </style> <div class="dark">dark</div> <div class="light">light</div>
▹ CSS Inline If For Style Queries
CSSInlineIfForStyleQuerieschromestatus.comThe CSS if() function provides a concise way to express conditional values. It accepts a series of condition-value pairs, delimited by semicolons. The function evaluates each condition sequentially and returns the value associated with the first true condition. If none of the conditions evaluate to true, the function returns an empty token stream. This allows web authors to express complex conditional logic in a simple and concise way. Example: <style> div { color: var(--color); background-color: if(style(--color: white): black; else: white); } .dark { --color: black; } .light { --color: white; } </style> <div class="dark">dark</div> <div class="light">light</div>
▹ CSS Inline If For Supports Queries
CSSInlineIfForSupportsQuerieschromestatus.comThe CSS if() function provides a concise way to express conditional values. It accepts a series of condition-value pairs, delimited by semicolons. The function evaluates each condition sequentially and returns the value associated with the first true condition. If none of the conditions evaluate to true, the function returns an empty token stream. This allows web authors to express complex conditional logic in a simple and concise way. Example: <style> div { color: var(--color); background-color: if(style(--color: white): black; else: white); } .dark { --color: black; } .light { --color: white; } </style> <div class="dark">dark</div> <div class="light">light</div>
▹ CSS Preferred Text Scale
CSSPreferredTextScalechromestatus.comExposes a user's preferred font scale to CSS. Currently, it is not practical for a page to detect if the user has changed their preferred font size via the Operating System's preferences. This CSS environment variable will reflect the scale chosen by the user.
▹ CSS Progress Notation
CSSProgressNotationchromestatus.comThe progress() functional notation returns a <number> value representing the position of one calculation (the progress value) between two other calculations (the progress start value and progress end value). progress() is a math function. The syntax of progress() is defined as follows: <progress()> = progress(<calc-sum>, <calc-sum>, <calc-sum>) where the first, second, and third <calc-sum> values represent the progress value, progress start value, and progress end value, respectively.
▹ CSS Reading Flow
CSSReadingFlowchromestatus.comThe reading-flow CSS property controls the order in which elements in a flex, grid or block layout are exposed to accessibility tools and focused via TAB keyboard focus navigation. This change implements the CSS reading-flow keyword values: * normal * flex-visual * flex-flow * grid-rows * grid-columns * grid-order * source-order See spec: https://drafts.csswg.org/css-display-4/#reading-flow The reading-order CSS property allows authors to manually-override the order within a reading flow container. It is an integer with default value 0. See spec: https://drafts.csswg.org/css-display-4/#reading-order Please find more thorough examples of how TAB keyboard navigation and accessibility is improved by this feature here: https://chrome.dev/reading-flow-examples/
▹ CSS Sibling Functions
CSSSiblingFunctionschromestatus.comsibling-index() and sibling-count() can be used as integers in CSS property values to style elements based on their position among its siblings, or the total number of siblings respectively. These functions can be used directly as integer values, but more interestingly inside calc() expressions. Example: li { margin-left: calc(10px * sibling-index()); }
▹ CSS Sign Related Functions
CSSSignRelatedFunctionschromestatus.comThe sign-related functions abs() and sign() compute various functions related to the sign of their argument. The abs(A) function contains one calculation A, and returns the absolute value of A, as the same type as the input: if A’s numeric value is positive or 0⁺, just A again; otherwise -1 * A. The sign(A) function contains one calculation A, and returns -1 if A’s numeric value is negative, +1 if A’s numeric value is positive, 0⁺ if A’s numeric value is 0⁺, and 0⁻ if A’s numeric value is 0⁻. The return type is a <number>, made consistent with the input calculation’s type.
▹ CSS System Accent Color
CSSSystemAccentColorchromestatus.comThis feature empowers web developers to enhance the visual appeal of their websites by leveraging the operating system's accent color for form elements. By utilizing the "accent-color" CSS property, developers can ensure that form elements such as checkboxes, radio buttons, and progress bars automatically adopt the accent color defined by the user's operating system. This feature is an enhancement to existing feature that is already shipped in Chromium: https://groups.google.com/a/chromium.org/g/blink-dev/c/WwYkLjbGhoA
▹ CSS Text Auto Space
CSSTextAutoSpacechromestatus.comInserts small spacings to match the established typographic rules automatically. The spec currently defines one rule for Han ideographic characters and one for French. The initial implementation focuses on the Han ideographic characters rule. Text written in Han ideographic writing systems often mixes multiple scripts, usually the Han ideographic scripts, Latin scripts, and ASCII digits. Small spacings when switching from and to non-Han ideographic scripts often help the readability. This property lets browsers insert such spacings automatically. This property has several values, including values for other writing systems. The initial implementation supports `normal` and `no-autospace`. The initial value is set to `no-autospace` to start conservatively and be more careful for the site compatibilities. Authors can add `text-autospace: normal` to enable the feature.
▹ CSS View Transition Auto Name
CSSViewTransitionAutoNamechromestatus.comContact emails vmpstr@chromium.org, nrosenthal@chromium.org Explainer None Specification https://drafts.csswg.org/css-view-transitions-2/#auto-vt-name Summary 'auto' uses the element's id attribute to generate a unique match for view transition cases. In absence of the id, it generates a unique id based on the element's identity and remains the same for this element. This is used in Single Page App or Multi Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ CSS View Transition Match Element
CSSViewTransitionMatchElementchromestatus.com'match-element' generates a unique id based on the element's identity and renames the same for this element. This is used in Single Page App cases where the element is being moved around and the desire is to animate it with a view transition Note this is split off from https://chromestatus.com/feature/6575974796492800 which contains additional discussions
▹ Database
Databasechromestatus.comNotRestoredReasons API has been launched as part of PerformanceNavigationTiming API. This PR specified the names of the reasons that User Agents can choose to expose. https://github.com/whatwg/html/pull/10154 This entry is about chromium changing the names of the reasons so that they match the ones specified. List of changes: "extension-messaging", "pending-permission-request", "not-main-frame", "frame-navigating", "timeout", "cookie-disabled", "cookie-removed", "printing", "web-database", "injected-javascript", "injected-stylesheet" -> "masked" "response-method-not-get"->"request-method-not-get" "serviceworker-version-activation" -> "serviceworker-version-activated" "serviceworker-added-after-bfcache" -> "serviceworker-added" "serviceworker-unregistration" -> "serviceworker-unregistered" "unload-handler" -> "unload-listener" "session-restored" -> null
▹ Device Orientation Request Permission
DeviceOrientationRequestPermissionchromestatus.comAllows developers to ask for permission to use the Device Orientation and Device Motion APIs. Access to these APIs is currently granted by default, and these new functions are part of the long-term plan to require requesting permission before using window.ondevicemotion and window.ondeviceorientation.
▹ Dialog New Focus Behavior
DialogNewFocusBehaviorchromestatus.comSome changes are being made to which element is selected to get focus when a dialog element is opened: 1. Make the dialog focusing steps look at keyboard focusable elements instead of any focusable element. 2. Make the dialog element itself get focus if it has the autofocus attribute set. 3. Make the dialog element itself get focus as a fallback instead of focus being "reset" to the body element.
▹ Document Isolation Policy
DocumentIsolationPolicychromestatus.comDocument-Isolation-Policy allows a document to enable crossOriginIsolation for itself, without having to deploy COOP or COEP, and regardless of the crossOriginIsolation status of the page. The policy is backed by process isolation. Additionally, the document non-CORS cross-origin subresources will either be loaded without credentials or will need to have a CORP header.
▹ Document Policy Include JS Call Stacks In Crash Reports
DocumentPolicyIncludeJSCallStacksInCrashReportschromestatus.comThis feature captures the JS call stack when a web page becomes unresponsive due to JavaScript code running an infinite loop or other very long computation. This helps developers to identify the cause of the unresponsiveness and fix it more easily. The JS call stack is included in the crash reporting API when the reason is unresponsive.
▹ Escape Lt Gt In Attributes
EscapeLtGtInAttributeschromestatus.comEscape "<" and ">" in values of attributes on serialization. This mitigates the risk of mutation XSS attacks, which occur when value of an attribute is interpreted as a start tag token after being serialized and re-parsed.
▹ Extended Text Metrics
ExtendedTextMetricschromestatus.comExpand the TextMetrics Canvas API to support selection rectangles, bounding box queries, and grapheme cluster-based operations. This new functionality should enable complex text editing applications with accurate selection, caret positioning, and hit testing. Additionally, cluster-based rendering facilitates sophisticated text effects such as independent character animations and styling.
▹ Face Detector
FaceDetectorchromestatus.comThe Face Detection API is a subset of the Shape Detection API which provides the ability to detect human faces and facial landmarks in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ File System Access API Experimental
FileSystemAccessAPIExperimentalchromestatus.comCurrently, the File System Access API does not support an efficient way to move or rename files or directories. This requires creating a new file/directory, copying over data (recursively, in the case of a directory), and removing the original. This process is slow, error prone (e.g. disk full), and can require re-uploading files in some cases. See https://github.com/WICG/file-system-access/pull/317
▹ Focusgroup
Focusgroupchromestatus.comThe Focusgroup feature will facilitate keyboard focus navigation using the keyboard arrow keys among a set of focusable elements.
▹ Gamepad Multitouch
GamepadMultitouchchromestatus.comExtend the Gamepad API to support multitouch surfaces (touchpads). Providing a touchpad API eases application implementation and provides greater functionality browser interoperability.
▹ Indexed Db Get All Records
IndexedDbGetAllRecordschromestatus.comThis feature adds the getAllRecords() API to IndexedDB's IDBObjectStore and IDBIndex. It also adds a direction parameter to getAll() and getAllKeys(). This functionality enables certain read patterns to be significantly faster when compared to the existing alternative of iteration with cursors. One key workload from a Microsoft property showed a 350ms improvement. getAllRecords() effectively combines getAllKeys() and getAll() by enumerating both primary keys and values at the same time. For an IDBIndex, getAllRecords() also provides the record's index key in addition to the primary key and value. getAllRecords() can optionally return records in either ascending or descending order. This option is also back-ported to the existing operations getAll() and getAllKeys().
▹ Install On Device Speech Recognition
InstallOnDeviceSpeechRecognitionchromestatus.comThis feature adds on-device speech recognition support to the Web Speech API, allowing websites to ensure that neither audio nor transcribed speech are sent to a third-party service for processing. Websites can query the availability of on-device speech recognition for specific languages, prompt users to install the necessary resources for on-device speech recognition, and choose between on-device or cloud-based speech recognition as needed.
▹ Inverted Colors
InvertedColorschromestatus.comAdds the `inverted-colors` media feature, an indication that the user agent or underlying operating system has forcibly inverted all colors, not a request to do so. This is sometimes provided as a simple accessibility feature, allowing users to switch between light-on-dark and dark-on-light text. Valid options are 'inverted' or 'none'.
▹ Language Detection API
LanguageDetectionAPIchromestatus.comA JavaScript API for detecting the language of text, with confidence levels. An important supplement to translation is language detection. This can be combined with translation, e.g. taking user input in an unknown language and translating it to a specific target language. Browsers today often already have langauge detection capabilities, and we want to offer them to web developers through a JavaScript API, supplementing the translation API. An enterprise policy (GenAILocalFoundationalModelSettings) is available to disable the underlying model downloading which would render this API unavailable.
▹ Layout Stretch
LayoutStretchchromestatus.comA keyword for CSS sizing properties (e.g. 'width', 'height') that allows elements to grow to exactly fill their containing block's available space. It is similar to '100%', except the resulting size is applied to the element's margin box instead of the box indicated by 'box-sizing'. Using this keyword allows the element to keep its margins while still being as large as possible. An unprefixed version of '-webkit-fill-available'.
▹ Media Capture Background Blur
MediaCaptureBackgroundBlurchromestatus.comThe Background Blur API allows web developers to use the native platform's API for camera background segmentation. As Background Blur has become one of the most used features on video conferencing apps like Teams, Meet, Zoom, and Webex, we want web apps to leverage the same platform APIs without completely relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud based solutions.
▹ Media Capture Voice Isolation
MediaCaptureVoiceIsolationchromestatus.comThis is about adding support in Chrome for the VoiceIsolation getUserMedia constraint (https://w3c.github.io/mediacapture-extensions/#voiceisolation-constraint). The constraint only takes effect on platforms where there is low-level support for voice-isolation style denoising. Currently this is limited to a selected number of ChromeOS devices, but further platforms will be added.
▹ Media Source Extensions For Web Codecs
MediaSourceExtensionsForWebCodecschromestatus.comExtends the Media Source Extensions API (MSE) to enable buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.
▹ Media Source New Abort And Duration
MediaSourceNewAbortAndDurationchromestatus.comThe Media Source standard long ago changed to disallow ambiguously defined behavior involving asynchronous range removals: * SourceBuffer.abort() no longer aborts SourceBuffer.remove() operations * Setting MediaSource.duration can no longer truncate currently buffered media Exceptions will be thrown in both of these cases now. Safari and Firefox have long shipped this behavior, Chromium is the last browser remaining with the old behavior. Use counters show ~0.001%-0.005% of page loads hit the deprecated behavior. Primarily small Russian sites. If a site hits this issue, playback may now break. Usage of abort() cancelling removals is increasing, so it's prudent to resolve this deprecation before more incompatible usage appears.
▹ Navigate Event Commit Behavior
NavigateEventCommitBehaviorchromestatus.comNormally, when navigateEvent.intercept() is called, the intercepted navigation commits (and therefore the URL updates) as soon as the NavigateEvent finishes dispatch. Adding a `precommitHandler` option to navigateEvent.intercept(), similar to `handler`, would defer the commit until that handler (and all other precommit handlers) are resolved, also allowing the handler to change the navigation's URL, info, status, and history handling behavior (push/replace).
▹ Navigation Id
NavigationIdchromestatus.comThis adds a Performance Timeline entry type, "back-forward-cache-restoration", which is emitted every time that a page is retrieved from the back-forward cache, and a field on all performance timeline entries, "navigationId", which can be used to tie performance events to the most recent navigation-like event. This allows developers to more easily use the performance APIs to compare the user experience of an SPA or a bfcache-eligible page with that of a traditional multi-page experience.
▹ Nested View Transition
NestedViewTransitionchromestatus.comAllow view-transitions to generate a nested pseudo-element tree rather than a flat one. This allows the view transition to appear more in line with its original elements and visual intent, as it enables clipping, nested 3D transforms, and proper application of effects like opacity, masking and filters.
▹ On Device Web Speech Available
OnDeviceWebSpeechAvailablechromestatus.comThis feature enables websites to support contextual biasing for speech recognition by adding a recognition phrase list to the Web Speech API. Developers can provide a list of phrases as well as updating them to apply a bias to the speech recognition models in favor of those phrases. This helps improve accuracy and relevance for domain-specific and personalized speech recognition.
▹ Paint Timing Mixin
PaintTimingMixinchromestatus.comExpose "paintTime" and "presentationTime" in event timing, element timing, LCP, long animation frames, paint timing. "paintTime" means the time when the rendering phase ended and the browser started the paint phase. "presentationTime" means the time when the "pixels reached the screen", which is somewhat implementation-defined
▹ Payment App
PaymentAppchromestatus.comThe API helps to develop new payment apps in web standard ways (e.g. service worker). If using them, payment app providers can provide simplified payment methods and user experiences.
▹ Payment Link Detection
PaymentLinkDetectionchromestatus.comAdds support for <link rel="facilitated-payment" href="..."> as a hint that the browser should notify registered payment clients about a pending push payment.
▹ Payment Request
PaymentRequestchromestatus.comTo help developers reduce friction in Payment Request flows, we are removing the user activation requirement. Spam and clickjacking mitigations are put in place to mitigate security and privacy risks with this change.
▹ Performance Navigation Timing Confidence
PerformanceNavigationTimingConfidencechromestatus.comWeb applications may suffer from bimodal distribution in page load performance, due to factors outside of the web application’s control. For example: * When a user agent first launches (a "cold start" scenario), it must perform many expensive initialization tasks that compete for resources on the system. * Browser extensions can affect the performance of a website. For instance, some extensions run additional code on every page you visit, which can increase CPU usage and result in slower response times. * When a machine is busy performing intensive tasks, it can lead to slower loading of web pages. In these scenarios, content the web app attempts to load will be in competition with other work happening on the system. This makes it difficult to detect if performance issues exist within web applications themselves, or because of external factors. Teams we have worked with have been surprised at the difference between real-world dashboard metrics and what they observe in page profiling tools. Without more information, it is challenging for developers to understand if (and when) their applications may be misbehaving or are simply being loaded in a contended period. A new ‘confidence’ field on the PerformanceNavigationTiming object will enable developers to discern if the navigation timings are representative for their web application.
▹ Permission Element
PermissionElementchromestatus.comProvide a new HTML element that interacts with the permission flow. The permission prompt is currently triggered directly from JS without the user agent having any strong signal of the user's intent. Having an in-content element that the user uses to trigger the permission flow allows for improved permission prompt UX for users as well as a recovery path from the "denied" permission state for sites. Explainer: https://github.com/WICG/PEPC/blob/main/explainer.md Instructions: https://github.com/WICG/PEPC/blob/main/HOWTO.md Developer facing documentation: https://developer.chrome.com/blog/permission-element-origin-trial
▹ Potential Permissions Policy Reporting
PotentialPermissionsPolicyReportingchromestatus.comIntroduces a new violation type called "Potential Permissions Policy violation", which will only look at Permissions Policy (including report-only policy) and the allow attribute set in iframes to detect the conflict between Permissions Policy enforced vs permissions propagated to iframes.
▹ Private Network Access Null Ip Address
PrivateNetworkAccessNullIpAddresschromestatus.comWe propose to block access to IP address 0.0.0.0 in advance of PNA completely rolling out. Chrome is deprecating direct access to private network endpoints from public websites as part of the Private Network Access (PNA) specification (https://developer.chrome.com/blog/private-network-access-preflight/). Services listening on the localhost (127.0.0.0/8) are considered private according to the specification (https://wicg.github.io/private-network-access/#ip-address-space-heading). Chrome's PNA protection (rolled out as part of https://chromestatus.com/feature/5436853517811712) can be bypassed using the IP address 0.0.0.0 to access services listening on the localhost on macOS and Linux. This can also be abused in DNS rebinding attacks targeting a web application listening on the localhost. Since 0.0.0.0 is not used in practice (and should not be used), but was overlooked during https://chromestatus.com/feature/5436853517811712, we're deprecating it separately from the rest of the private network requests deprecation.
▹ Rel Opener Bcg Dependency Hint
RelOpenerBcgDependencyHintchromestatus.comExtends the use of the "opener" rel type to same-window navigations to signal to the browser that the destination page will open a new window and the referring page expects to be able to access it. Some user agents perform browsing context group changes on navigation that aren't strictly necessary for security in order to improve performance. This results in named window reuse not being possible across a back navigation. Annotating an anchor element with "opener" will signal to the user agent that performing a browsing context group change would break a future opener relationship.
▹ RTC Data Channel Priority
RTCDataChannelPrioritychromestatus.comMany applications have multiple media flows of the same data type and often some of the flows are more important than others. The priority setting can be used to indicate the relative priority of various flows. The priority API allows the JavaScript applications to tell the browser whether a particular media flow is high, medium, low or of very low importance to the application.
▹ RTC Encoded Frame Set Metadata
RTCEncodedFrameSetMetadatachromestatus.comAllow WebRTC Encoded Transform API to manipulate audio and video frame metadata. Some WebRTC Encoded Transform use cases involve manipulation of not only the payload of encoded video / audio frames but also its metadata. Some examples: * Altering the timestamp of a frame to introduce a delay, * Changing the mime type of the frame if the transform changes the type of the payload. * Forwarding of media to a new peer connection set up to use different metadata values Use cases: https://w3c.github.io/webrtc-nv-use-cases/#live-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#stored-encoded-media https://w3c.github.io/webrtc-nv-use-cases/#auction Issue link: https://github.com/w3c/webrtc-nv-use-cases/issues/77
▹ RTC Rtp Script Transform
RTCRtpScriptTransformchromestatus.comThis API allows processing of encoded media flowing through an RTCPeerConnection. Chromium shipped an early version of this API in 2020. Since then, the spec has changed and other browsers have shipped the updated version of the spec (Safari in 2022 and Firefox in 2023). This launch refers to the latest spec version and is part of Interop 2025. This launch does not cover the generateKeyFrame method, which is still under discussion https://github.com/w3c/webrtc-encoded-transform/issues/143 https://github.com/w3c/webrtc-encoded-transform/issues/271 https://github.com/w3c/webrtc-encoded-transform/pull/269
▹ Scoped View Transitions
ScopedViewTransitionschromestatus.comExposes element.startViewTransition() on arbitrary HTML elements. The element establishes a scope for the transition, which means that the transition pseudo-elements are affected by ancestor clips and transforms, and multiple transitions on separate elements can run concurrently.
▹ Selection Across Shadow DOM
SelectionAcrossShadowDOMchromestatus.comThis feature ships two new API methods for the Selection API: * Selection.direction which returns the selection's direction as either "none", "forward" or "backward" * Selection.getComposedRanges() which returns a list of 0 or 1 “composed” StaticRange A “composed” StaticRange is allowed to cross shadow boundaries, which normal Ranges cannot. For example: const range = getSelection().getComposedRanges({ shadowRoots: [root] }); If the selection crosses a shadow root boundary that isn’t provided in the shadowRots list, then the StaticRange's endpoints will be “rescoped” to be outside that tree. This makes sure we do not expose unknown shadow trees.
▹ Shadow Root Reference Target
ShadowRootReferenceTargetchromestatus.comReference Target is a feature to enable using IDREF attributes such as `for` and `aria-labelledby` to refer to elements inside a component's shadow DOM, while maintaining encapsulation of the internal details of the shadow DOM. The main goal of this feature is to enable ARIA to work across shadow root boundaries. A component can specify an element in its shadow tree to act as its "reference target". When the host component is the target of a IDREF like a label's `for` attribute, the reference target becomes the effective target of the label. The shadow root specifies the ID of the target element inside the shadow DOM. This is done either in JavaScript with the `referenceTarget` attribute on the `ShadowRoot` object, or in HTML markup using the `shadowrootreferencetarget` attribute on the `<template>` element.
▹ Signature Based Integrity
SignatureBasedIntegritychromestatus.comThis feature provides web developers with a mechanism to verify the provenance of resources they depend upon, creating a technical foundation for trust in a site's dependencies. In short: servers can sign responses with a Ed25519 key pair, and web developers can require the user agent to verify the signature using a specific public key. This offers a helpful addition to URL-based checks offered by Content Security Policy on the one hand, and Subresource Integrity's content-based checks on the other.
▹ Soft Navigation Heuristics
SoftNavigationHeuristicschromestatus.comExposes the (experimental) soft navigation heuristics to web developers, using both PerformanceObserver and the performance timeline. This feature reports two new performance entries: - "soft-navigation", for user interactions which navigate the page. Defines a new timeOrigin to help slice the performance timeline. - "interaction-contentful-paint", which reports on the loading performance of interactions (beyond just next paint), used as LCP for soft-navigations.
▹ Svg Anchor Element Rel Attributes
SvgAnchorElementRelAttributeschromestatus.comThe SVGAElement interface in SVG 2.0 allows manipulation of <a> elements similar to HTML anchor elements. Supporting the rel and relList attributes enhances security and privacy for developers. This alignment with HTML anchor elements ensures consistency and ease of use across web technologies.
▹ Text Detector
TextDetectorchromestatus.comThe Text Detection API is a subset of the Shape Detection API which provides the ability to detect and optionally transcribe text in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag.
▹ Tpcd
Tpcdchromestatus.comThis experiment exposes a temporary set of APIs which provide access to browser-determined treatment and control groups to support opt-in server side testing of the third-party cookie deprecation.
▹ Viewport Segments
ViewportSegmentschromestatus.comThe Viewport Segments API allows developers to adapt their website/webapp layout to target foldable devices. The viewport segments defines the position and dimensions of a logically separate region of the viewport. Viewport segments are created when the viewport is split by one or more hardware features (such as a fold or a hinge between separate displays) that act as a divider; segments are the regions of the viewport that can be treated as logically distinct by the author.
▹ Web App Installation
WebAppInstallationchromestatus.comThe Web Install API allows a web site to install a web app (same or cross domain). This functionality allows the creation of web based catalogues that can install PWAs directly from the web and into multiple platforms. https://aka.ms/webinstall
▹ Web App Scope Extensions
WebAppScopeExtensionschromestatus.comAdds a "scope_extensions" web app manifest field that enables web apps to extend their scope to other origins. Example usage: { "name": "Example", "display": "standalone", "start_url": "/index.html", "scope_extensions": [ {"type" : "origin", "origin" : "https://example.com"} ] } This allows sites that control multiple subdomains and top level domains to be presented as a single web app. Requires listed origins to confirm association with the web app using a .well-known/web-app-origin-association configuration file. { "https://sample-app.com/": { "scope": "/" } }
▹ Web Authentication Immediate Get
WebAuthenticationImmediateGetchromestatus.comA mediation mode for navigator.credentials.get() that causes browser sign-in UI to be displayed to the user if there is a passkey or password for the site that is immediately known to the browser, or else rejects the promise with NotAllowedError if there is no such credential available. This allows the site to avoid showing a sign-in page if the browser can offer a choice of sign-in credentials that are likely to succeed, while still allowing a traditional sign-in page flow for cases where there are no such credentials.
▹ Web Codecs Orientation
WebCodecsOrientationchromestatus.comIntroduces "rotation: int" and "flip: bool" values to various video related interfaces in WebCodecs so that developers can work with frame sources that have orientation (E.g., Android cameras, certain media). The VideoFrame interface grows the ability to create VideoFrames with arbitrary rotation and flip as well as accessors for this information on the VideoFrame object. The VideoDecoderConfig object gains rotation and flip fields that are emitted on decoded VideoFrame objects automatically. The VideoEncoder class gains mechanisms for passing rotation and flip information from encode() to the VideoDecoderConfig emitted as part of EncodedVideoChunkMetadata. If encode() is called with frames with different orientations a non-fatal exception will be thrown. configure() may be used to reset the allowed orientation.
▹ Web Crypto Ed25519
WebCryptoEd25519chromestatus.comThis feature adds support for Curve25519 algorithms in the Web Cryptography API, namely the signature algorithm Ed25519
▹ WebGPU Experimental Features
WebGPUExperimentalFeatureschromestatus.comFunctionality added to the WebGPU spec after its first shipment in a browser. ServiceWorker and SharedWorker support is added to WebGPU, aligning with existing WebGL capabilities.
▹ Web Identity Digital Credentials
WebIdentityDigitalCredentialschromestatus.comWebsites can and do get credentials from mobile wallet apps through a variety of mechanisms today (custom URL handlers, QR code scanning, etc.). This Web Platform feature would allow sites to request identity information from wallets via Android's IdentityCredential CredMan system. It is extensible to support multiple credential formats (eg. ISO mDoc and W3C verifiable credential) and allows multiple wallet apps to be used. Mechanisms are being added to help reduce the risk of ecosystem-scale abuse of real-world identity (see https://docs.google.com/document/u/1/d/1L68tmNXCQXucsCV8eS8CBd_F9FZ6TNwKNOaFkA8RfwI/edit).
▹ Web Preferences
WebPreferenceschromestatus.comThe Web Preference API aims to provide a way for sites to override the value for a given user preference (e.g. color-scheme preference) in a way that fully integrates with existing Web APIs.
▹ Web XR Layers
WebXRLayerschromestatus.comWebXR Layers offers a more efficient way of drawing immersive content. In addition to support for native color and depth textures and texture arrays, it also provides support for different layer types that are managed by the system compositor (as opposed to javascript).
▹ Web XR Spec Parity
WebXRSpecParitychromestatus.comUpdates our implementation of the WebXR specification to provide a few attributes that have been added over time. These are generally attributes that developers find useful or enable small performance improvements. These include but are not limited to: Setting/Querying the framerate on an XRSession (including supported framerates), Angular/Linear Velocities, Predicted Display Time of a Frame, isSystemKeyboardSupported, and XRWebGLLayer fixedFoveation
