Mac client 16.1.388
The link to the release notes in the MAU notification was broken, are those somewhere so we can see what has changed? For me, chats are now in separate windows again and the option to have them all in one pane is gone from preferences. This is a significant UI change right as we were about to roll the client out to 300+ Mac users. It also sucks as tabbed chats was a huge plus over Lync.
