#175567 better fix for error in your SQL syntax in og_mail(). patch by grugnog2. modified by moshe weitzman.

#162559 fix moving of nodes during group deletion. patch by Duncan Pierce. Slightly modified by Moshe Weitzman to add array_unique() in og_save_ancestry() and added comments at top of new og_group_child_nids()

major enhancements to views integration. 'posts in specified group' filter and the analogous argument now accept strings like 3,4,7 and 3+4+7. like taxonomy urls, this elects posts that are in all those groups are any of those groups. also added a filter and an argument which accept substrings on group titles so you can see all nodes belonging to groups with the word 'marketing' in them. this fulfills some of the needs for subgroups.

#163510 View filter 'Posts in current group' broken when there is no group in the context. patch by recidive.

defer sending of notification emails until cron time. this speeds up posting for big groups with lots of email subscribers. the job_queue module is required for this feature. if not present, notifications are sent in real time (just like before this change).

remove 'website' as a field for groups. in order to get this back, add 'website' to your node type(s) that behave as groups. i left the website field in the og table. sites that want to preserve this data need to migrate it to their new field.

added an og_requirements() which gently warns if og access control is disabled and if job_queue.module is disabled.
