Microsoft Edge in the Windows 10 Creators Update. With the Creators Update, also upgrading Microsoft Edge with dozens of new features and under-the-hood improvements to make the best browser on Windows 10 faster, leaner, and more capable than ever.

This release updates the Windows web platform to EdgeHTML 15, the fourth release of EdgeHTML and a major step forward both in terms of the browser user experience, web platform capabilities, and fundamentals like performance, efficiency, and accessibility. In this post, we’ll share a quick overview of what’s new in each area, for both users and web developers.

Web developers can start testing EdgeHTML 15 today by updating their Windows 10 device, or by downloading a free virtual machine from Microsoft Edge Dev.

Organize your web with new tab management experiences

Windows users spend more than half of their time on the web, and it’s all too easy to get tangled up in the chaos of search results, sites, and other content that can build up over hours, days, or weeks of browsing.

Microsoft Edge now lets you set your tabs aside for later, sweeping them aside and organizing them neatly in a special section for easy access when you’re ready.

Simply click the new “Set these tabs aside” button next to your row of tabs, and they are moved out of sight. When you’re ready to come back to them, just click the “Tabs you’ve set aside” icon, and you get a tidy, visual view of previous sessions. Restore one tab, or restore the full set!

Microsoft Edge now includes the ability to preview all your open tabs at once, so you can get back to what you’re looking for in a snap.

Simply click the “Show tab previews” arrow to the right of your new tab button, and your tabs will expand to show a preview of the full page. You can scroll through this list to see as many tabs as you have open – when you find what you want, just click it to get back to browsing!

New reading experiences in Microsoft Edge

Microsoft Edge now lets you read books from right inside the browser, putting your favorite e-books from the Windows Store or from EPUBs on the web alongside your reading list and other content you expect to find in your browser.

You can find books in the new “Books” section of the Microsoft Edge Hub, and a wide selection of books for every taste in the Windows Store.

 

Pushing the frontier of energy efficiency

Thanks to major improvements in Microsoft Edge, like encouraging HTML5 content over Flash, improving the efficiency of iframes, and optimizing hit testing, Microsoft Edge on the Creators Update uses 31% less power than Google Chrome 57, and 44% less power than Mozilla Firefox 52, as measured by our open-source efficiency test that simulates real-world browsing.

These improvements translate into hours more browsing time for our customers – time to finish a crucial report while you’re at a coffee shop with no power, or to watch an extra movie on a long flight. In a head-to-head video rundown test, Microsoft Edge outlasted Google Chrome by more than three hours when streaming video!

Responsiveness that puts the user first

Microsoft Edge continues to lead by those measures, but ultimately any single benchmark can only tell part of the story. In EdgeHTML 15, we’ve focused on making Microsoft Edge feel faster and more responsive, even when the page may be busy or hung, by prioritizing the user’s input above other activity, and optimizing rendering for real-world scenarios.

These improvements dramatically reduce input blocking on busy sites – put simply, the browser responds much more quickly to user input like clicking links or scrolling with the keyboard, even when a page may be busy loading or executing JavaScript in the background.

That just scratches the surface – for example, over the past two releases, we’ve been working on an ongoing, multi-year refactoring of the Microsoft Edge DOM tree, which is now substantially complete. Together with a number of performance optimizations, this has resulted in a more than twofold improvement in performance in many real-world scenarios, as measured by the Speedometer benchmark, which simulates real-world app patterns using common frameworks.

Modern capabilities for web developers

The Windows 10 Creators Update upgrades the Windows web platform to EdgeHTML 15, which introduces a number of new, modern capabilities for web developers. A few of these are highlighted below – you can find the full list of changes on the Microsoft Edge Dev Guide.

Simpler web payments with the Payment Request API

The new W3C Payment Request API enables simpler checkouts and payments on Windows 10 PCs and phones. In Microsoft Edge, the Payment Request API connects to the user’s Microsoft Account (with the user’s permission), allowing easy access to payment information.

CSS Custom Properties

CSS Custom Properties (formerly called CSS Variables) are a new primitive value type to fully cascade variables across CSS properties. Custom Properties enable the same fundamental use cases as variables in CSS pre-processors, but have the additional benefits of being fully cascaded, being interacted with via JavaScript, and not requiring the additional build step to work.

WebVR Developer Preview

Microsoft Edge now supports the WebVR 1.1 draft specification, which has been collaboratively authored by Mozilla, Google, Samsung, Microsoft, Oculus and others. Developers can now use this API to create immersive VR experiences on the web with the recently available Windows Mixed Reality dev kits. You can even get started without a headset using the Windows Mixed Reality Simulator.

Brotli

Brotli is a compression format that achieves up to 20% better compression ratios with similar compression and decompression speeds (PDF). This ultimately results in substantially reduced page weight for users, improving load times without substantially impacting client-side CPU costs. As compared to existing algorithms, like Deflate, Brotli compression is more efficient in terms of file size and CPU time.
