Doesn't seem to know what version it is. After install it appears to phone home and says current version is 2.2 and newer 2.2.2 is available. But, the installed version actually is 2.2.2 according the file naming and file info.
For the paranoid, there should be an option to stop it from doing a version check. Interestingly, LittleSnitch didn't report any outgoing connections.
