Apple has released iOS 8.1 beta 2 for those registered in the iOS Developer program. The latest build arrives versioned as 12B407 and is said to include bug fixes and feature improvements to the mobile operating system.
Users who are currently running the first beta of iOS 8.1 on a compatible iPhone, iPad, ro iPod touch will find the update available through the OTA mechanism in Settings > Software Update. The delta update is fairly small, ranging in size from 50MB to 80MB to install. Registered developers can also find the iOS 8.1b2 IPSW available to download through the iOS Developer Center.
Separately, a new build of Apple TV software has been released, and Xcode 6.1 Golden Master 2 is also available to developers.
iOS 8.1 is expected to bring Apple Pay support to devices which support the mobile payments feature, and is also hoped to resolve many ongoing bugs and quirks with the existing iOS 8 releases, ranging from crashes, wi-fi issues, Bluetooth connectivity problems, and seemingly random poor battery performance. At the moment, users on MacRumors Forums have not reported any new features or changes with iOS 8.1 beta 2.
iOS 8.0.2 is the most recent publicly available version of the mobile operating system.
