"A few days back we reported on a new Mutter release, which is
the window and compositing manager for GNOME 3.0, and now with the
GNOME 2.29.91 beta release coming up on Wednesday there is also the
release of another new GNOME 3.0 component. Perhaps the single
biggest new component for the GNOME 3.x stack is the GNOME Shell
and this is the package that just reached version 2.29.0. GNOME
2.29.0 brings a lot of improvements."
