    Introducing EdgeHTML 13, first platform update for Microsoft Edge

    Last week, the first major update for Windows 10 began rolling out to over 110 million devices, including improvements in all aspects of the platform and experience. This update brings Microsoft Edge’s rendering engine to EdgeHTML 13, which Windows Insiders have been previewing for the last few months.

    When we first introduced Microsoft Edge as “Project Spartan” back in January, we promised an evergreen browser. This means developers can rely on Microsoft Edge users always having the latest version of the rendering engine, and can expect frequent updates to the platform with new features and standards support. With EdgeHTML 13, we’re excited to deliver a broad set of major new platform features only a few months after the first public release of Microsoft Edge, as an automatic update to all Current Branch customers of Windows 10.

    Feature updates in EdgeHTML 13

    Back in August, we gave our first peek at our priorities for this release, as well as some longer term goals for future releases. If you have been watching the Microsoft Edge changelog, you may have seen these features lighting up build-by-build in the Insider Program. These updates bring Microsoft Edge to a score of 458 on HTML5Test – an improvement of 56 points in just a few months, and 117 points over Internet Explorer 11.

    HTML5Test measures declared support for features defined in the HTML5 specification as well as extensions and related specifications.

    Here are the highlights of what’s now supported in EdgeHTML (for a full breakdown, visit the changelog):


    File APIs

    User Input




    • Restored support for docking the F12 Developer Tools

    Web Components

    Feature updates in Chakra

    In addition to the improvements in EdgeHTML, this release also includes major improvements and new feature support in Chakra, the JavaScript engine powering Microsoft Edge. Major features like asm.js are now enabled by default. With these updates, Microsoft Edge is by a wide margin the highest-scoring desktop browser in the Kangax ES6 compatibility table, which measures support for the component features of ES2015, perhaps the largest update in JavaScript history.

    Kangax ES6 scores for Microsoft Edge and other desktop browsers.

    In addition, the “Experimental JavaScript features” flag under about:flags now includes experimental support for early ES2016 features, including Async Functions and the Exponentiation operator.

    Here’s the full list of the major new features supported in Chakra:

    • ES2016 Async Functions (behind “Enable experimental JavaScript features” flag)
    • ES2016 Exponentiation operator (behind “Enable experimental JavaScript features” flag)
    • asm.js is now enabled by default (previously behind a flag); see our blog post and demo
    • ES2015 Classes now enabled by default (previously behind a flag)
    • ES2015 Destructuring now available behind the Experimental JavaScript features flag

    Many Windows 10 devices, one web platform

    This update marks a special moment for the Windows 10 web platform as we ship the same version of EdgeHTML to all Windows 10 devices: PCs, Windows 10 phones (via the Windows Insider Program), and even Xbox One. Whether it’s adaptive images on phones with the <picture> element and extended srcset, or even in-browser gaming on the Xbox One with WebGL and GamePad API, Microsoft Edge empowers users and developers alike to be confident in a consistent, modern, and powerful experience across devices.

    New end-user features in Microsoft Edge

    While this blog is focused on developer features, this release also updates the Microsoft Edge app to Microsoft Edge 25, which includes powerful new features like Tab Preview, synced Favorites and Reading List, and wireless multimedia casting for video, audio, and photos. You can learn more about the updates to Microsoft Edge and other Windows apps on the Windows Experience blog.

    Tab Preview in Microsoft Edge

    This update also includes major security improvements in Microsoft Edge, with industry-leading code integrity enforcement in the Windows kernel, and updates to SmartScreen to protect users from drive-by attacks in the browser. We’ll be exploring each of these features in separate posts soon.

    What’s next?

    This is just the first step in a journey of delivering Microsoft Edge updates regularly, and we’re excited to get right back to work on our next set of improvements. As always, the Windows Insider Program is the best way to preview our upcoming features early, and we’ll continue to share details on our plans as soon as we begin development. Expect to hear more about our next feature investments and our priorities for 2016 in the coming months. In the meantime, we welcome your feedback and look forward to seeing what you do with the powerful new capabilities in Microsoft Edge!

    Very nice! This browser has so much potential, but MS really needs to deliver extensions for this ASAP, among other most requested features.

    Right! They're focusing on the glitter instead of what could make Edge worth it's weight in gold.

    This old news (NOVEMBER 16, 2015 10:00 AM) keeps being regurgitated here - why? - and it still only scores 453 on the page, and not 458, as stated on the Microsoft Windows Blog.

    The first mention of EdgeHTML 13 on this forum was 21 September back in build 10547 when it was first released.

    One of the biggest features projected to land on Windows 10 is extension support for Edge browser, and recent leaks have confirmed that Microsoft is already internally testing it and could allow insiders to do the same very soon in preview builds.

    Earlier today, the Redmond-based software giant has rolled out Windows 10 build 11082, which is also the very first Redstone preview build, and although Microsoft hasn’t publicly announced any new features, it turns out there are some gems hiding in there.

    One of them is extension support for Edge browser, which has been spotted by Twitter user @h0xod, who has confirmed that there are several registry entries for this feature in build 11082.

    For the moment, the extension menu can indeed be activated in this very first Windows 10 Redstone build, but it can’t be used for anything. Extensions aren’t yet working on Windows 10, so although the options to access them are there, the feature isn’t functional

    This is a very good starter and there working in the good area. 530 remains the number to reach and its directly proportionnal to what users are asking. Surfing the web is not the same ball game anymore.

    Who said that Linux was ain't good?

    Chrome Stable Version 47.0.2526.106 (64-bit) Debian
    Merry X-mass to all of you!
