The WordPress 3.0 Beta is available. This update is very significant because it merges Wordpres MU the regular branch of WordPress. For people who manage multiple WordPress sites, but were unable to use WordPress MU, this change could be a significant timesaver. It is also particularly useful for people who work at organizations where each department wants their own separate blog or website and they don’t want to have to deal with the administrative overhead of a bunch of separate installs.
