Just as the BuddyPress 1.7 Release Candidate emerged, so did the bbPress 2.3 Release Candidate. Jared Atchinson just announced this over at the bbPress blog
bbPress 2.3 introduces forum-specific search functionality, so that your users are able to search your forum posts without interfering with your blog posts. It simplifies the fancy topic and reply editors, enabling only the functionality your users should see. Lastly, we’ve included more forum migration tools to help you transition to bbPress from Vanilla, Mingle, and SimplePress.
