Sony releases PS Vita firmware v1.66 following yesterday's v1.65 update
No bugs here, hopefully

Yesterday, Sony released and then swiftly pulled PS Vita firmware v1.65 after numerous players complained that they couldn't gain access to the adhoc play feature in PSP games once they'd updated their software.
The Japanese company has today released firmware v1.66 - basically, a bug-free version of firmware v1.65.
So, the download includes all of the new features that were introduced in yesterday's firmware update, including the ability to toggle your system's alerts on and off.
There isn't much new here for gamers, but check out the full list of changes and additions below.
- 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.
