The latest version of Microsoft Edge for Windows 10 Redstone 2 shows new HTML5 support that helps the browser score an impressive 500 out of 555 points on HTML5test.

While users are still installing the Anniversary Update on their computers, it doesn't mean that development of Windows 10 has concluded. Microsoft is already working on "Redstone 2", and the first test preview for the next version of the operating system is now rolling out to Insiders. Windows 10 build 14901 is now available for Insiders with PCs enrolled in the Fast ring. According to the company, the new version doesn't introduce any significant changes, as the development team is currently making structural improvements to OneCore (the shared "heart" of Windows across devices) to get the operating system ready for new features. However, if you look closely, you'll see some real improvements coming to Microsoft Edge. Best VPN providers 2020: Learn about ExpressVPN, NordVPN & more

Improvements for Microsoft Edge on build 14901 Starting with Windows 10 build 14901, Microsoft Edge version number jumps from 38.14393 to version 39.14901. Microsoft Edge version 39 doesn't bring new visual elements or features but compared to version 38 there some exciting new changes inside the Developer Settings, which you also know it as the about:flags page. Under Composition, you can now select between Selfhost, Stable, and Canary composition engines, which replaces the Windows.UI.Composition option.

In the WebRTC section, we're also seeing that Microsoft is adding a new option to enable WebRTC 1.0 in the web browser. (For those unfamiliar, WebRTC stands for "Web Real-Time Communication", and it's a web standard that allows support voice, video, text, and peer-to-peer file sharing without the need for an extension.)

Then there is the new "Service Workers" feature, which allows Microsoft Edge to support rich offline experiences, push notifications, background sync, cash storage, and other functionalities that usually would require a native application. The currently available options in the experimental settings are: Enable service workers

Enable push notifications

Enable background sync

Enable service worker cache storage Finally, this new version of the web browser also includes a new network option called "Fast Networking," which allows you to enable fetch based network stack.
