Donncha has announced the release of WordPress MU version 2.7 today. Donncha states that this release is mostly a code sync release but it also contains quite a few bug fixes. The most notable change in WordPress MU is the addition of Viper007bond’s admin bar. Upgrading to the latest release should be as simple as overwriting the old files with the new ones. However, always make a backup copy first before doing anything! Congrats goes out to Donncha and to everyone who submitted a patch for the slickest version of MU to date. (MU now has the same backend design as WordPress 2.7)
