BuddyPress 1.7.2 was released a little while ago. It contains some bug fixes but the most notable items include several MySQL Injection possibilities that have been patched. 1.7.2 is being classified as a recommended upgrade for anyone using BuddyPress 1.5 or above.
I’m keeping tabs on BuddyPress because at some point in the future, this site will be utilizing it combination with bbPress.
