Apple has officially released iOS 8.1 to the public. Announced last week during Apple’s iPad Event, iOS 8.1 brings support for Apple Pay to the iPhone 6 and iPhone 6 Plus, enables SMS Continuity between iOS 8.1 devices and Macs running OS X Yosemite, enables iCloud Photo Library for all users and brings back the much-requested Camera Roll that was removed in iOS 8.0 to be replaced with a “Recently Added” album.

A number of other smaller fixes and improvements are also included. iOS 8.1 is available other as an over-the-air update or by updating via iTunes on a Mac or PC.
Update: iOS 8.1 also resolves issues when using AirPlay mirroring from an iPhone 6 Plus to a second- or third-generation Apple TV. iPhone UI mirroring looks noticeably cleaner and completely fills the screen when the iPhone is in landscape mode.
