BuddyPress was update to version 1.8.1, from version 1.8. Changelog:
- Fix default sort order for BP_Group_Member_Query to be last_modified
- Fix incorrect template hierarchy path for members directory templates
- Fix meta_query parameters for bp_has_groups() and bp_has_activities, to prevent duplicate results and other issues with multiple meta query clauses
- Fix user activity mentions feeds, which were incompletely implemented in BP 1.8
- Fix regression in BP_Group_Extension that caused fatal errors when using certain BP plugins on PHP 5.2.x
- Remove calls to $wpdb->escape(), deprecated by WordPress 3.6
