BuddyPress 1.0.1 was released yesterday. This point release fixes a number of security issues in the 1.0 version so it is a critical upgrade for everyone currently running BuddyPress. There is also a number of other bug fixes so please review the release history for more information.
BuddyPress 1.0.1 is now available. The easiest way to upgrade is through the plugin browser on your WordPress MU installation, you should see a notification for the latest version. If you would like to upgrade manually you can download the latest then simply overwrite your existing files. Please make sure you backup first.
Embarrassingly, I missed the release of BuddyPress 1.0 which was released a few weeks ago. That's too bad because I've been watching the development of BuddyPress since it's infancy in the development cycle. I had hoped to give BuddyPress more attention when it when the 1.0 version had been released.
BuddyPress will transform an installation of WordPress MU into a social network platform. BuddyPress is actually a suite of WordPress plugins and themes, each adding a distinct new feature. BuddyPress contains all the features you’d expect from WordPress but aims to let members socially interact. I've always wanted to give WordPresss MU a try but I've never had a project that needed the software. Someday it will happen...
