Apple has pushed out the fourth beta version of the iOS 9.1 mobile OS update. The software is designed to fix bugs that appeared in the public build of 9.1 and introduce a few new features, like a larger emoji set and an option to disable contact photos in the Messages app.

The most recent beta introduced four new wallpapers. The latest build is available to both developers and public beta testers.

A new build of tvOS has also been published for users on pre-release hardware.

Both operating systems can be downloaded from their respective over-the-air update screens or through the Apple Developer Center.

We’ll keep this post updated with any new changes we find.
