 * Function get_users_listing now return list of users except guest and deleted users. Previously
   deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
   and not included in get_user function, it will not be returned by get_users_listing.
+* The signature of the add() method of classes implementing the parentable_part_of_admin_tree
+  interface (such as admin_category) has been extended. The new parameter allows the caller
