- added rel="ostatus:attention" links for group delivery - added events for plugins to override group profile/permalink pages - pulled Notice::saveGroups up to save-time so we can override; it's relatively cheap and gives us a clean list of target groups for distrib time even with customized delivery. - fixed notice::getGroups to return group objects as expected - added some doc on new parameters to Notice::saveNew - 'groups' list of group IDs to push to in place of parsing - messages that come in via PuSH and contain local group targets are delivered to local group members - messages that come in via PuSH and contain remote group targets are delivered to local members of the remote group Todo: - handle group posts that only come through Salmon - handle conflicts in case something comes in both through Salmon and PuSH - better source verification - need a cleaner interface to look up groups by URI - need a way to handle remote groups with conflicting names
