@Banshee is finally on twitter, where we'll always keep you up to date and sometimes entertained if you follow us.
We also just released Banshee 2.0.1, a stable, bug-fix-only follow on to 2.0.0!
We've got 2.1.x releases scheduled leading up to 2.2 in September. We'll be porting to Gtk# 3 and dropping a bunch of legacy deps in the process, while still supporting users on older distros. I e-mailed banshee-list more about what that means and how we'll do it.
