    The upgrade from 4.1.x to 4.2 shouldn't be painful. I can't think of any pitfalls when replacing the 4.1.x library to 4.2.

    Sencha Cmd is now at version 3.1 and can be downloaded here:

    This might be related to migration, but after I move my application from ExtJS 4.1.1 to 4.2 it started to get slower.
    I'm using my application mostly on machines with IE9 and on 9 from 10 usages I get script timeout exception in IE.
    I must admit that on Chrome my app works faster, but on IE it is only worst.
    Anyone had the same issue?

    I didn't do any tweaks with my code, I just replaced all ext-all.js with new one.
    Are there any guides (general guides) what can be changed in code to speed everything up?

    I don't why performance would suffer with a migration from 4.1.x to 4.2. I've not really heard that as a complaint from the community specifically.

    How best to streamline an app is a fairly big question and probably requires some code review though the implementations of each aspect of the application.

    That said, there was a blog post that Nige White (animal) put together a while back that, while written under the 4.1 banner, applies to 4.2 just as neatly:

    Upgrading from 4.1 to 4.2 is a nightmare. I'm in the middle of an attempt and a simple full screen window with a border layout and a grid in the center region yields nothing but this: http://puu.sh/gNyyf/a9f287b8be.png
