Sony has issued a minor, optional update for the PlayStation Vita system software, updating the machine to version 2.12.
The software update offers changes that aren't that important - but if you've been having any trouble with your Vita it might be worth checking for this update as it may smooth out issues you've been having.
The official PlayStation twitter account keeps it vague, simply stating that v2.12 improves "system software stability during use of some features." It's out now - just point your Vita to the upgrade screen. Thanks, TSA.
