# Polypane 25.1: DRM support and bug fixes Polypane 25.1 is now available, and it brings DRM support through Widevine, a new reopen last closed tab feature and a number of improvements and fixes. ![Polypane icon](/img/brand/polypane-icon.svg)**What's [Polypane](/)?** Polypane has everything a browser has, plus all the tools you need to build responsive, fast, accessible, and SEO-friendly websites and apps with multi-viewport synchronised previews, comprehensive device emulation and extensive accessibility tooling. ## DRM support Polypane 25.1 adds support for DRM through Widevine, which means you can now watch and listen to DRM protected content in Polypane. It took a few starts and stalls to get Widevine integrated into Polypane properly without compromising on the security of Polypane, but it's here now. ![Polypane playing a netflix DRM video](/static/netflix-drm-b6d720bcbb3133e0d7d7b31a2e0eedfd.jpg) _That black rectangle when making a screenshot is the DRM protection in action._ We want to thank the team at [CastLabs](https://castlabs.com/) for their responsiveness and willingness to change their build process to get this working, as well as [Mike Maietta](https://github.com/mmaietta) for his help integrating the required features into our build system. ## Reopen last closed tab You can now re-open closed tabs with ⇧ ⌘ T. It won't help you build better websites, but it should save you some time when you accidentally close a tab you didn't mean to close. It's a small feature, but one that we hope will make your life just a little bit easier. ## Show only Links with issues The [links outline](/docs/outline-panel/#links) now has an option to show only broken links so you can focus on just the links that have issues. This is especially useful for large pages with many links, as it allows you to quickly identify and fix broken or problematic links without having to scroll through all the working ones. ![Polypane showing only links with issues on this page](/static/linkissues-61f0c817a3b380b4eca11630b80986f2.png) ## Form autofilling improvements Our [form autofilling](/docs/form-autofill/) feature makes it really easy to quickly fill out an entire form with realistic data, but it also filled in `hidden` inputs. Since those are often used to communicate extra data to the server, this could cause issues. Starting from 25.1 we leave those hidden inputs alone, which should make form autofilling more reliable. Thanks Mathieu for the request! ## Elements panel fixes We added support for comments in our [25.0.1 release](/blog/polypane-25-browser-extensions-with-manifest-v-3-form-outlines-and-chromium-138/#polypane-2501-changelog), but in doing so accidentally broke support for inspecting web component internals in the Elements panel. This has been fixed, so you can now inspect shadow DOMs again. Thanks Mark for making us aware of this! ![Elements panel with an opened shadowRoot](/static/webcomponents-5367c74cfab3a30e48c27495c902f6b0.png) We've also fixed an issue where some CSS wouldn't be shown because we couldn't parse the oklch color space correctly. Later this year we will roll out even more wide color space support across the app. ## Meta panel improvements The [meta panel](/docs/meta-information/) now warns you when a robots meta tag prevents indexing. While we already [tested against your `robots.txt`](/docs/meta-information/#robotstxt), we now also test against the contents of the meta tag. Thanks Laurent for the suggestion! ![Meta panel showing a robots meta tag that prevents indexing](/static/robotsmeta-644f236379703a96c2a492e1cd3a0d94.png) We've also solved various bugs that occurred for some people like the app freezing when trying to [hide social media previews](/docs/meta-information/#hiding-and-sorting-the-social-card-previews) (Thanks George!), more robust [testing of structured data](/docs/meta-information/#structured-data) (Thanks Laurent!) and a fix for microdata not always being shown despite being detected. ## Get Polypane 25.1 Polypane is available for Windows, Mac and Linux in 64 bit and ARM versions.
