PS Vita gets a mini firmware upgrade, PS+ minis now work

The Vita will soon (live now apparently) get a dapper little firmware upgrade, to version 1.65, offering some fairly basic functionality improvements including:

UPDATE: The firmware upgrade has been removed due to a technical issue, no word on when it will be back.

UPDATE to the UPDATE: PS Vita's firmware update is now available again (now called v1.66).

•  A “Notification Alert” option will be added to Settings, so you can toggle alerts on or off “After 10 minutes” will be added to the time options under Power Save Settings 
• An Arrow icon will now appear when PS Vita finds new activities in the LiveArea 
• Caps Lock will be supported in the On Screen Keyboard

Undocumented, but apparently the case according to some tweets, is a fix so that PlayStation+ users can now play their minis on the Vita. It also adds a percentage counter for game installation, improvements to the frequency of Near updates, and a background download option when manually selecting sleep mode.
