Today Sony released a nonmandatory firmware update for PS Vita, making it the third system update to grace the handheld in ten days. The firmware apparently fixes some issues with camera use in the Japanese PS Vita title Dream Club Zero Portable, which begs the question why the game can’t be patched directly in order to rectify these bugs.
As was the case with the previous two firmware updates, the download clocks in at 97 MB. Thankfully it’s entirely optional and you’ll still be able to use the PlayStation Network on firmware version v1.66. Sony’s description for the new firmware is typically vague: “The update improves stability for some PlayStation Vita titles.”
I can’t see a reason to update your PS Vita unless you’ve imported Dream Club Zero Portable from Japan so you may as well hold off until the next compulsory update arrives.
