Apple has today released iOS 9.2.1 to the public, bringing a number of bug fixes and under-the-hood improvements to the operating system.
According to Apple's release notes via MacRumors, iOS 9.2.1 includes:
security improvements and bug fixes, including a fix for a significant Mobile Device Management issue that affected enterprise customers.
Based on our testing of the two iOS 9.2.1 betas which preceded this public release, it does not appear as though there are any accessibility-specific improvements in iOS 9.2.1. However, it is also worth noting that we did not identify any new accessibility bugs in this release, and that the focus across the board appears to have been on under-the-hood optimizations.
As we always like to stress at this point, it is impossible for us to test all devices, apps, and use cases. So, it is possible that we have overlooked some changes, regressions or improvements. With this in mind, we would greatly appreciate your help in ensuring that the information on this page is as complete and accurate as possible. If you spot any accessibility-related changes in iOS 9.2.1, please do let us know in the comments.
iOS 9.2.1 is available via Over-the-Air Update (Settings> General> Software Update) or from iTunes on the Mac or PC. As always, we would encourage you to make a backup before installing this update.
