Edge was originally built with Microsoft's own proprietary, but is currently being rebuilt as a -based browser, using the engine. Edge includes integration with, and a reading mode. Unlike Internet Explorer, Edge does not support. Support was developed and added in preview builds in March 2016, and released with the Windows 10 Anniversary Update on August 2, 2016. Microsoft Edge extensions are distributed via.
Microsoft debuted Edge for and in late 2017. Desktop view for Microsoft Edge on Microsoft Edge is the default web browser on Windows 10, and consoles, replacing. Microsoft initially announced that Edge would support the legacy (MSHTML) layout engine for backwards compatibility, but later said that, due to 'strong feedback', Edge would use a new engine, while Internet Explorer would continue to provide the legacy engine.
With all the fuss surrounding Windows 10’s new look, the reintroduction of the taskbar, and the integration of Cortana and Universal apps, you might have missed one of the OS’s biggest new.
Favorites, reading list, browsing history and downloads are viewed at the Hub, a providing functionality similar to Internet Explorer’s Downloads manager and Favorites Center. The browser includes an integrated Adobe Flash Player and a reader. It also supports.
Edge does not support legacy technologies such as ActiveX and Browser Helper Objects, and instead uses an extension system. Internet Explorer 11 will remain available alongside Edge on Windows 10 for compatibility; it will remain nearly identical to the Windows 8.1 version and not use the Edge engine as was previously announced. Edge integrates with Microsoft's online platforms in order to provide voice control, search functionality, and dynamic information related to searches within the address bar. Users can make annotations to web pages that can be stored to and shared with, but can't save HTML pages to their own computers. It also integrates with the 'Reading List' function and provides a 'Reading Mode' that strips unnecessary formatting from pages to improve their legibility. Preliminary support for was added in March 2016, with build 14291; three extensions were initially supported. Microsoft indicated that the delay in allowing extensions and the small number was due to security concerns.
EdgeHTML is a developed for Edge. It is a of that has removed all legacy code of older versions of Internet Explorer and rewritten the majority of its source code to support web standards and interoperability with other modern browsers. EdgeHTML is written in. The rendering engine was first released as an experimental option in Internet Explorer 11 as part of the Windows 10 Preview 9926 build. EdgeHTML is meant to be fully compatible with the layout engine used by Safari, Chrome and other browsers. Microsoft has stated that 'any Edge–WebKit differences are bugs that we’re interested in fixing.'
A review of the engine in the beta Windows 10 build by AnandTech found substantial benchmark improvements over Trident; particularly JavaScript engine performance, which had come up to par with that of Google Chrome. Other benchmarks focusing on the performance of the found EdgeHTML to perform much better than Google Chrome. HTML5 standards Edge originally lacked support for open media standards such as and, but these were later added in Edge 14.14291.
As of October 9, 2018, Edge 17 scored 492/555 on, comparable to Firefox 59 which scored 491/555, but lagging behind Chrome 66 which scored 528/555. Development In December 2014, writing for, technology writer reported that Microsoft was developing a new web browser codenamed 'Spartan' for Windows 10. She said that 'Spartan' would be treated as a new product separate from Internet Explorer, with Internet Explorer 11 retained alongside it for compatibility. In early January 2015 obtained further details surrounding 'Spartan' from sources close to Microsoft, including reports that it would replace Internet Explorer on both the desktop and mobile versions of Windows 10. Microsoft officially unveiled 'Spartan' during a Windows 10-focused keynote on January 21, 2015. It was described as a separate product from Internet Explorer; its final name was not announced. 'Spartan' was first made publicly available as the default browser of Windows 10 Technical Preview build 10049, released on March 30, 2015.
The new engine used by 'Spartan' was available in Windows 10 builds as part of Internet Explorer 11; Microsoft later announced that Internet Explorer would be deprecated on Windows 10, and would not use the 'Spartan' engine. On April 29, 2015, during the keynote, it was announced that 'Spartan' would officially be known as Microsoft Edge. The browser's logo and branding was designed to maintain continuity with the branding of Internet Explorer.
The Project 'Spartan' branding was used in versions released after Build 2015. On June 25, Microsoft released version 19.10149 for Windows 10 Mobile which included the new brand. On June 28, version 20.10158 followed for the desktop versions, also including the updated branding.
On July 15, Microsoft released version 20.10240 as the final release to Insiders. The same version was rolled out to consumers on July 29.

Finally, on November 19, the update was also made available as part of the Technical Preview 4. In November 2017, Microsoft released ports of Edge for.
The apps feature integration and synchronization with the desktop version on Windows 10 PCs. Due to platform restrictions and other factors, these ports do not use the same layout engine as the desktop version, and instead use OS-native -based engines. On December 6, 2018, Microsoft announced major changes to Edge, including that it will be re-based on, using the same rendering engine as but with enhancements developed by Microsoft.

The JavaScript Runtime (JSRT) APIs to host ChakraCore were originally designed for Windows, so they inevitably had a few Windows dependencies – for example, Win32 usage of UTF16-LE encoding for strings, where other platforms might use UTF8-encoded strings. As part of enabling cross-platform support, some of the JSRT APIs have been refactored and redesigned to allow developers to write platform agnostic code to embed ChakraCore. Maintaining backwards compatibility is a core principle that we follow – so applications written with the previous set of JSRT APIs on Windows will continue to work as is. You can build the engine and write a Hello-world app to get started with ChakraCore on the Windows/Linux/OS X.
