Microsoft today released Windows 10 Preview Build 17063 to Windows Insiders in the Fast Ring and Skip Ahead. This build comes with several new improvements for Edge browser. Microsoft Edge gets a new Dark theme with darker blacks, and much better contrast with all colors, text, and icons making it easy to navigate and more visually pleasing. It also gets Fluent Design elements like Reveal on the navigation buttons, action buttons, buttons in the tab bar, as well as on lists throughout Microsoft Edge. It also gets an updated Acrylic in the tab bar and in-active tabs, allowing more color to show through.
In this build, Microsoft is also making it easier to add and manage bookmarks for EPUB and PDF books. Users can now add bookmarks and manage their list of bookmarks from the same location making it really easy for them to manage their bookmarks from one location.
Starting with this build, Microsoft Edge will support Service Workers and the Push and Cache APIs allowing web pages to send push notifications to your Action Center or refresh data in the background, even when the browser is closed. It also improves offline support for websites which uses locally cached data when the cache is up to date, or when the device has a poor connection.
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.
This build also adds gesture experience for Precision Touch Pads allowing users to use gestures like pinch and zoom, or two-finger panning on web sites. For example, you can now pinch-to-zoom on a map in Bing Maps to zoom in the map without zooming the entire page.
