IE11 has just been released (as a developer preview) and i cannot find the IE7/8/9/10-emulator in IE11 dev tools. Does anyone know where to find them now ?
This question is related to

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).
Read my answer there for a fuller explaination, but in short:
They removed it deliberately, because compat mode is not actually really very good for testing compatibility.
If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.
The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.
