The security release of WordPress 2.8.2 means that WordPress MU also needs to be upgraded, and the new release is available now. However, Donncha O Caoimh also notes that a couple of other bugs has been fixed, including the upgrade notice one.
The multi user version of WordPress, called WordPress MU, is finally available in version 2.8.1. You can download it from the official site, as always. This is the first WordPress MU release in the 2.8 branch, which might be a bit confusing but the version numbering is tied to the single user version of WordPress, so you’ll just have to live with it. For changes, refer to the WordPress MU trac in general, and the timeline in particular.
The community plugin for WordPress MU, BuddyPress, has been updated to 1.0.2. This isn’t a crucial update, but it does fix some bugs, says Andy Peatling, so you should hit that update button from within the admin interface. Personally, I’m happy to learn that BuddyPress 1.1 and onwards will manage language files better, since you need to re-upload those after every update. Very good.
A while back there was a poll on the BuddyPress website about what should be tackled next. BuddyPress is a plugin for WordPress MU that turns your install into something of a social network. It is currently out in 1.0.1.
The results are in and among the things we’ll see in BuddyPress 1.1, apparently due August 17, are filtering of the activity stream, group categories and tags, image posting to wire as well as quick posting to blogs through the theme, and some other things. Not counting bug fixes an other things that might arise along the way of course.
