I wasn't in closed beta, and haven't paid close attention to version numbers, so all I can say is that all the versions I've seen have done it. Not specifics of which versions that was.
I have reverted (as I noted in that topic) because of concerns about losing the ability to actually use the client to install and launch my games, something which I've seen a number of users report as a problem with Galaxy 2.0 and which hasn't happened to my knowledge with older builds.
