The result is the same when comparing nightly builds. Actually IE updates each month now. Previously only critical updates were included on “patch Tuesdays”, but now features are added too. That is not to say that these particular features will be included in monthly updates to the stable version of IE11.

The VMs are not going anywhere. This is an additional service for those that can’t or don’t want to use virtual machines, or find this more convenient.

> IE11 just got prefetch and pre rendering, something the other browsers have had for years

Actually, Safari still doesn’t support either, and Firefox doesn’t support prerender. See http://status.modern.ie/prerenderattribute?term=pre and http://status.modern.ie/prefetchattribute?term=pre

The data from the links above is pulled in from Google‘s ChromeStatus site.

Also IE is updated regularly now. Feature updates are often included in patch Tuesday updates, such as big upgrades to WebGL and WebDriver support. As features are implemented (see in development in the links above) they're evaluated to see if they will be included in IE11 updates.

You’ll be pleased to know that we just updated it yesterday. A good chunk of ES6 is now under development. See the IE blog for further info: http://blogs.msdn.com/b/ie/archive/2014/09/18/updates-to-our...

Windows Phone 8.1 Update is final yet. It is in developer preview. You can get the preview right now by registering as a developer and downloading the Windows Phone for Developers preview app. See https://dev.windows.com/en-us/develop/phone-updates

Warning: you may void your warranty.

You can get free VMs at https://modern.ie/en-gb/virtualization-tools . And also a free 3 month BrowserStack trail from the same site.

Thank you very much. Unfortunately the job is of such a nature that I won't be able to use this but the pointer is much appreciated.

I believe the data from the Chakra (IE’s JS engine) team hasn’t been updated yet.

It’s under consideration.

Microsoft are contributing to Object RTC, so I see this as unlikely.

There are only 13 features listed there not currently supported in IE and supported by Chrome, Safari, and Firefox. Of those, 4 are currently in development.
