I’ve just read that WordPress MU 2.7.1 has been released a few days ago. Here’s some more information about what’s in this release:
* A revamped plugin system thanks to Andy Peatling. Plugins installed in the plugins directory rather than mu-plugins can be activated and deactivated on all blogs with one click.
* The admin bar was removed. It’ll be stuffed into a plugin instead. Must talk to Viper007Bond about that.
* A new “My Blogs” page where a user’s blogs are listed and personal “per blog” settings can be configured. It’s empty right now but it’s easy to add settings to it via plugins. Imagine having a different “Display Name” on each blog you write on! See SetupMenu and HandleFormPOST in the just removed admin bar for example code. That code uses actions rather than filters but it’ll get you started.
* The site admin can now set a Global Dashboard blog for users who don’t have blogs. Those users will be added to this blog rather than the main blog. The default role of users on that blog can also be set but if they’re not “Subscribers” they won’t be moved if you change the Global Dashboard.
It’s a great release and a worthwhile update for anyone on WordPress MU, more essential than an appetite suppressant for a chronic overeater. Not only are there a number of extra features, but there are also some security issues which have been addressed. So if you’re using WordPress MU, take note of this release and upgrade as soon as you can.
