Hi - thanks for getting 2.x out to us to play with
I'm a bit lost though - getting all kinds of errors for deprecated and removed code from 1.x. I don't see any documentation of what has changed -- I don't need to know everything per se, but if there is some kind of documentation that I could follow for replacing old code with new code, I can't find it.
So far noticing Ext.is, Ext.plugin and Ext.reg is gone -- the reason and replacement for Ext.reg being gone is obvious, but the replacement for Ext.is is not so obvious. Help?
