There is surely no doubt that WordPress MU rocks. For Wordpress MU fans, there is a good news. WordPress MU 2.6 beta 1 is now available. The beta has got many new features and some security fixes. WordPress MU now includes post revisioning, gears support for faster loading, theme previews, better SSL support and much much more. Taking the name into question, why is the version named 2.6 rather than just 1.6? Folks at Automattic say that they have named this version as 2.6 rather than 1.6 in order to eliminate confusion between versions. Minor MU versions will probably append a letter to the version.
