On June 16, Microsoft announced that Internet Explorer will now have a Developer Channel release which can run side-by-side with the production/GA version of Internet Explorer on Windows 7 and Windows 8.x. This feature, which has long been available in Google’s Chrome browser and Mozilla’s Firefox, is a pleasant surprise to those who use Internet Explorer.
This release is a continuation of the effort Microsoft, and especially Internet Explorer team has started, to become developer-friendly by being proactive in communication about the roadmap and the features. This release, unlike the previous developer previews Microsoft created, not only runs side-by-side with the existing version of Internet Explorer but also includes changes to the UI as they are made.
Some of the key updates in this release include:
Updates to F12 developer tools
An enhanced debugging experience with event breakpoints that help you get to your event-driven bugs faster.
Richer analysis capabilities throughout the Memory and UI Responsiveness profilers, which support further reduction of noise through multi-dimensional timeline filter, while further increasing the semantic value of the data being reported by lighting up performance.measure() based instrumentation and dominator folding.
An improved navigation experience that provides more keyboard shortcuts (ctrl+[ and ctrl + ]), as well as new header notifications, which allows you to quickly determine whether any of the profiling tools are running or how many errors your page has.
The complete list of updates are on MSDN here.
Support for WebDriver standard
IE Developer Channel also comes with support for the emerging WebDriver standard through which Web developers can write tests to automate Web browsers to test their sites. It’s a programmable remote control for developing complex user scenarios and running them in an automated fashion in your Web site and browser. See how you can setup WebDriver in the IE Developer Channel, and try out this sample WebDriver project.
Support for Gamepad API standard and improved WebGL support
IE Developer Channel also improves WebGL performance and adds support for instancing extension, 16-bit textures, GLSL builtin variables, and triangle fans. This release improves our Khronos WebGL Conformance Test 1.0.2 score from 89% to 94%.
The team is promising frequent updates to the Developer Channel and we shall see how frequent that is. Given the pace and cadence across various other groups at Microsoft, it could be anywhere from two weeks (Xbox Music) to a month (Xbox One, Power BI) or three-four months (Windows, Windows Phone). Whatever it is, for developers this is much better than anything Internet Explorer has done in the past.
