Apple has rolled out a new iOS 8.1.1 beta to registered developers, delivering yet more bug fixes and improving performance on older devices. The release comes just two weeks after iOS 8.1 was made available to the public.

Apple doesn't typically provide developers with smaller releases like this one ahead of their public debut, but it seems the Cupertino company is playing it safe following the horrible issues that made their way into users' hands with the botched iOS 8.0.1 release in late September.

Developer betas allow new releases to be tested by a wider range of users on a wider range of devices, so that problems can be picked up before they make their way into the wild. We don't expect to see too many issues with this release, however, which is designed to make iOS 8 even better.

According to Apple's release notes, iOS 8.1.1 fixes a series of bugs and improves stability. Those using iOS 8 on older devices — such as the iPhone 4s and the iPad 2 — should also enjoy greater performance.

Providing there are no problems with this build, it's likely it will be made available to all within the next fortnight. More significant iOS 8.2 and iOS 8.3 updates are planning for release next year, 9to5Mac reports, and they're expected to bring Apple Watch compatibility, split-screen multitasking on iPad, and lots more.
