I just started TextMate and it prompted me to install this new version 2.0 beta 12.  That's all great.  But I'd like to know what changed from the previous version.  I've looked at the various TextMate places (textmate.org and github) but can't find any kind of list of "what changed" in the new version, and not even a list of issues that got closed.

Just curious because TextMate is a great tool that I rely on and I'd like to know what's going on.
