New Microsoft Edge features
Fluent updates in Microsoft Edge: Microsoft Edge now supports Reveal on our navigation buttons, action buttons, buttons in the tab bar, as well as on lists throughout Microsoft Edge (such as in the HUB: Favorites, Reading, History, Downloads), making navigating Edge UI easier and more delightful. We’ve also refreshed both the Light and Dark themes, with more distinct transparency, darker blacks, and much better contrast with all colors, text, and icons.
Bookmark button and flyout become one: This release consolidates the functions to add and manage bookmarks into one button in all EPUB and PDF documents.**
Offline web sites and push notifications: Microsoft Edge now supports Service Workers and the Push and Cache APIs. These new web standards allow web pages to send push notifications to your Action Center or refresh data in the background, even when the browser is closed. In addition, certain web pages can now work offline or improve performance, by using locally cached data when the cache is up to date, or when your device has a poor connection. You can learn more about these features in our post Service Workers: Going beyond the page. These features lay the technical foundation for Progressive Web Apps on Windows 10 – we’ll have lots more to share about this topic soon on the Microsoft Edge Dev Blog!
Web Media Extensions Package: This build installs the Web Media Extensions package for Microsoft Edge, which extends Microsoft Edge and Windows 10 to support open-source formats (OGG Vorbis and Theora) commonly found on the web. Try out your favorite OGG content (such as Wikipedia videos or audio)! We will be monitoring feedback from this feature in Insider flights to eventually expand to broader availability to Microsoft Edge customers in the Current Branch.
Gesture Improvements for Precision Touch Pads: This build introduces a new gesture experience for Precision Touch Pads (found on Surface and other modern Windows 10 devices). You can now use gestures like pinch and zoom, or two-finger panning, to achieve the same interactions on web sites that you can do with a touch screen today. For example, you can now pinch-to-zoom on a map in Bing Maps to zoom in the map without zooming the entire page. Developers can learn more about how this change is implemented and how to make sure your sites are ready for modern input experiences over at our blog post, Building a great touchpad experience for the web with Pointer Events.
New web platform features
- The Service Workers family of features (Service Worker, Push API, Cache API, Fetch API) is now enabled by default in Microsoft Edge. You can learn more about these features in our post Service Workers: Going beyond the page. Note that Service Workers are not yet enabled by default in Hosted Web Apps.
- CSS backdrop-filter is now enabled by default
- Subresource integrity is now enabled by default
- Precision Touch Pad Pointer Events: Microsoft Edge will now fire Pointer Events with a pointerType of “touch” in response to PTP gestures. You can learn more about this change in our blog post, Building a great touchpad experience for the web with Pointer Events
- Added support for minlength on textarea and input
- This build preloads the Web Media Extensions package for Microsoft Edge, which extends Microsoft Edge and Windows 10 to support open-source formats (OGG Vorbis and Theora) commonly found on the web.
Known issues in build
- Push notifications do not work correctly in this build due to a bug preventing the Push permission from being saved correctly. This should be resolved in the next Windows Insider release.
