A few weeks ago (for the first time, at the
DevCon 2014 conference) we said that we are striving to build a more open dialogue between the Internet Explorer team and the developer community. Today we are introducing the Internet Explorer Developer Channel, a full-featured browser designed to give developers a chance to evaluate the functionality and new browser features that the Internet Explorer team is working on.

The IE Developer Channel is available for download from Microsoft Download Center for
Windows 8.1 and
Windows 7 SP1 with Internet Explorer 11.

The IE Developer Channel can operate independently of IE11. It contains all the features of the current version of Internet Explorer and some new features that we are currently working on. Check out the new features and tell us what you think about them on Twitter

F12 Developer Tool Improvements
In April, we
talked about the new features of the F12 tools in IE11 for Windows 8.1 with an update aimed at better data presentation in the DOM Explorer and in the memory and performance analysis tools. The IE Developer Channel demonstrates even more new features, such as:
- Improved debugging tool, with event breakpoints , which will allow you to find errors related to events even faster.
- Rich analysis capabilities in Memory and UI Responsiveness profilers. The update will provide noise reduction due to the appearance of a multi-dimensional timeline filter . At the same time, developers will be able to get more complete data thanks to the performance.measure () and dominator folding panels.
- Improved navigation: added new hot key combinations (ctrl + [and ctrl +]), and new header notifications to allow developers to quickly determine if any profilers are running and how many errors are found on the page.
A full list of new features is available on
MSDN .

The IE Developer Channel supports the new
WebDriver standard, with which web developers can automate tests to test their sites. WebDriver is a programmable remote control site that allows you to check complex scenarios for its use automatically. Learn how to set up WebDriver in
this article and try out the
sample WebDriver project .
Use the Xbox controller for web games
Want to try playing web games with an Xbox gamepad? The IE Developer Channel supports the
Gamepad API standard, which allows you to work with the controller using JavaScript. Try connecting a controller and play one of these games
Escape from XP ,
Hover.IE or
Atari Arcade !
Use the gamepad to defeat Windows XPOther innovations also include increased performance with WebGL, support for instance extensions of classes (instancing extension), 16-bit textures, embedded GLSL variables, and triangle fans (triangle fans). This release improves
Khronos WebGL Conformance Test 1.0.0 from 93% to 97%. Learn more about these and other WebGL APIs on
MSDN .
The first of many upcoming Developer Channel releases
We continue to work on introducing support for new features and standards in Internet Explorer and will constantly share early versions of code through the IE Developer Channel. You can always see the latest list of new features on the
DevChannel.Modern.IE page. All of the IE Developer Channel innovations are also listed on
Status.Modern.IE , our new portal with a plan for introducing support for promising standards to our web platform.

The current release of the IE Developer Channel uses a combination of App-V code and client to work in parallel with IE11. Virtualization has a negative impact on browser performance, so we do not recommend using the IE Developer Channel to measure your site’s performance. We also do not recommend using this version in a corporate environment. To learn more about known issues, check out our list of
frequently asked questions .
We are waiting for your opinion on the Internet Explorer Developer Channel on Twitter,
