That's right, we finally did it! It's up right now, and if you follow the directions on http://www.turbogears.org/ you'll get 2.2.0.
I'd like to take a minute to thank Alessandro Molina in particular. I did what support I could, but this release really belongs to him. Please pass along congratulations and thanks to him. And if there's bugs, I'll take the blame myself for not doing more to help.
The full changelog is below.
