Download previous versions of ExtJs

Question

Where can previous versions of Extjs can be downloaded from ?

Specifically I would like to get extjs-4.1.1a and btw what is up with the 'a' is this different from extjs-4.1.1?

Solution

From this repos:

https://github.com/probonogeek/extjs/commits/master https://github.com/bjornharrtell/extjs/commits/master

For the missing 4.1.3 here is another repo: https://github.com/zenoss/zenoss-extjs/blob/master/ext-4.1.3.zip?raw=true
