Donncha has let it slip that WordPress MU version 2.7 is being released today. Donncha explained that this release is mostly a code sync release but it also contains some bug fixes. The biggest change in WordPress MU is the addition of Viper007bond’s admin bar.

Upgrading to 2.7 should be as easy as overwriting any old files with new ones. As always, make a backup before making any big changes. Shout outs go to Donncha, and everyone who submitted a patch for the best looking version of MU ever.
(MU now has the same backend design as WordPress 2.7)
