With GNOME 2.28 having been released
last month, all efforts are focusing on GNOME 3.0
, which is the first major overhaul of this Linux desktop environment in years. Two of the key components to the GNOME 3.0 desktop are Mutter, the new window/compositing manager, and GNOME Shell, the shell for how a user interacts with the desktop. There have been early preview releases
for both Mutter and GNOME Shell, but out this afternoon are 2.28.0 releases for both of these software packages.
While carrying the "2.28" tag, these releases of Mutter and GNOME Shell are only to serve as previews with their code still undergoing very active development. The stable releases will not come until GNOME 3.0, which will come next March.
To both Mutter and GNOME Shell are plenty of changes since their last development releases in early September. The 2.28.0 release announcements for Mutter and GNOME Shell can be read here
