Apple has released the latest version of its mobile operating system, iOS 8.1.1, to iPhone and iPad devices.
The software, available over-the-air or as a download via iTunes, lands with a number of performance improvements for older iPhone 4s and iPad 2 devices, which users have complained were significantly slower since the iOS 8 update.
There have been no reported issues so far with iOS 8.1.1, however.
In other Apple updates of the day, OS X Yosemite also saw updates to its Wi-Fi reliability and Mail app, putting the version number at 10.10.1. The update also addressed a number of bug fixes relating to Time Machine, waking from sleep, and notifications.
Apple TV, the company's "hobby" set-top box, was also updated with maintenance fixes.
