Re: bbPress 1.0 released
At the moment, WP and WPMU are separately maintained. But there are plans to merge the two codebases into one, don’t expect that in the next couple of months. More like next year sometime.
So if you’re planning on using BuddyPress in a few months, I would recommend getting acquainted with WPMU 2.7.1 since it works with the latest version of BuddyPress. This is just my advice, but I wouldn’t upgrade to WP 2.8.
Moving over from WP to WPMU is not that straightforward. You have to do a number of things in order to get things right.
Since this is straying away from the original topic, create a new thread about this and others can chime in.
