As Kevin points out, TurboGears 1.0.2 has been released. A whole bunch of fixes and changes as one expects for a stable release, including support for Python 2.5, with contributions from some 20+ people. This, the same day (ie, yesterday) I hear, yet again, how "nobody is going to support TurboGears 1.0". Ah, the misinformation - one has to wonder why people feel the need to create it. I've met too many trusting people who've believed a lot of it, and it's quite depressing.
I think many of TG's improvement happened out of shore, such as TurboLucene, TurboMail, gsquickstart, tgcrud, OpenID, YUI and jquery plugins.
For example, TG 1.0.2 has gsquickstart command extension which provide kid quickstart replacement for genshi. TG 1.0.2 also has multilingual supported search engine(TurboLucene) and easy customable admin interface generator (tgcrud). They are not in core but they bring more vitalities to TG.
