Group Chat
I think most people have noticed it is better. So far, I have been able to comment in groups such as Firestorm Support without a problem, a group I seldom could connect to. I could listen, but not post comments, about half or more of the time.

Posting to any large group was a problem. That has now mostly been resolved.
We are losing the open post of any chat that starts after I login. In some cases it is not noticeable. In others it is apparent. The Lindens are aware of it.
Today grid status reported the internal utilities servers would be getting updates. In the Server Scripting meeting we learned that additional changes to group chat were being rolled out. So, this is likely that change going into place. The Lindens say not to expect visible improvements. That doesn’t mean there aren’t any, just that they are not likely to be as noticeable as previous changes.
