Minor maintenance update
As anticipated, Apple has released iOS 7.1.1 via iTunes and iOS' over-the-air update mechanism. The code is simply a maintenance release, primarily fixing keyboard responsiveness, as well as glitches when using Bluetooth keyboards while VoiceOver is on. For iPhone 5s owners, the patch improves Touch ID fingerprint recognition.
Although Touch ID was well-received when it debuted, within a few months, some users began complaining that the feature was inexplicably failing. Apple took steps to deal with the problem in iOS 7.1, but appears to have had work left to do.
