A few days after pushing the first iOS 9.3 beta to developers, Apple is now rolling the update out to a wider group of users.

iOS 9.3 beta 1 is now available to public testers in Apple Beta Software Program. You can grab the update over the air by heading into Settings > General > Software Update. The iOS 9.3 beta is available on devices running iOS 9, which includes phones going back to the iPhone 4s, iPad models back to the iPad 2 and iPad mini, and both the fifth and sixth generation iPod touch models.

Despite being an x.1 update, iOS 9.3 is a pretty major software upgrade. One of the biggest new features is Night Shift, which will automatically make the display warmer at night. Studies have shown that exposure to the blue light from screens can make it difficult for you to sleep, so Night Shift aims to make nighttime screen use easier on your eyes.

Also included in iOS 9.3 is the ability to lock Notes with a passcode or Touch ID; improvements to Apple News, Health, and CarPlay; and new education features. The biggest new education add-on is multi-user support. Folks have been asking for multi-user capabilities on the iPad for years now, and while the feature appears to be education-only in iOS 9.3, it’s possible that Apple could open it up to everyone in the future.

There’s no word on when iOS 9.3 will roll out to the public, but if you’re in the Apple Beta Software Program, you can snag it right now. Just keep in mind that this is a beta — and the first version of the iOS 9.3 beta, at that — so performance and battery life may not be super awesome.
