Second Life viewer version 1.19.0 isn't all that far away, though there's still some things blocking the progress so the exact timing is in doubt however Joshua Bell from Linden Lab provided some insights on the upcoming changes on the public Second Life Developer's Mailing list.

The most standout item on that summary was a change to the way group IM sessions work. Right now, you're automatically connected to a new group IM session for one of your groups, and a tab pops open for it as soon as the first message for that session is sent. Disconnecting from that session has been a little problematic lately, with session tabs popping back open again. All that was pitched to change.
