Biggest change this time is the new rating system (aka "likes reloaded").The like system has been converted into a more flexible post rating system. More here.Fixed lots of issues with uncookied sessions (= sessions that use PHPSESSID) and pretty URLs.Notifications (aka alerts) now respect the member- and board ignore lists. Events triggered by users on your ignore list or happening in ignored boards will be filtered out from the list of unseen notifications. Note that this is dynamic - the events are still there, just filtered from display, so when the ignore lists are updated (for example, you remove a previously ignored user), those hidden events will come back.Same as above, but for the activity stream. Events in ignored boards or generated by ignored users are hidden from display.It is now possible to view who rated a post by clicking on the number of ratings. Note that this requires permission to view detailed ratings (can_view_ratings) if the rating is a "non-neutral" one (= a rating that can modify the reputation points balance).
