- `bp_avatar_get_version()` can be used to get a version of an avatar according to its timestamp. Since <a href="http://buddypress.trac.wordpress.org/changeset/13175">[13175]</a> the `BP_Attachment_Avatar` class is using a timestamp inside the avatar file name instead of a generated unique string (`uniqid()`), this change allows us to request avatars according to the timestamp included into their names.
- `bp_avatar_get_avatars_history()` can be used to get the file objects list of previously uploaded avatars.
