One positive thing about this release is that the chat window's messages flow much faster. Have only been able to run this release for about a minute at a time. Crashes often, particularly badly on a sketchy AirPort connection: the first bad packet seems to throw up an error dialog which you must dismiss, followed by the immediate crash of the program. Aside from problems like this, which may be fixable, I'd like to see an option to use a chat client strictly for chat, leaving private messages to go to the IM client of choice (in my case, Fire).
