It's 1:20am in my timezone, I just pulled out Gnome 2.20 from package.mask, which is great because both Fedora and Ubuntu still haven't been released (that was my personal goal for this release).
I'm tired, I probably messed a few things up, so don't hesitate to open bugs in bugzilla
NB: do not try to mix and match Gnome 2.20 if you're not running an unstable system. Such bugs will be closed.
