Research In Motion has quietly rolled out another release of BlackBerry Messenger. Previously seen in some leaked OS is now available in BlackBerry App World and via direct download. No change log has been issued for the release which, is really getting kind of annoying since Research In Motion used to be one of the few to actually issue change logs. So that said, we're sure it's just bug fixes and overall a maintenance release but, let us know in the comments if you spot anything different.
