Apple is starting the week off with some piping hot beta software.

iOS 9.3 beta 6 is now available to both registered developers and public testers in the Apple Beta Software Program. The update is a small one, weighing in at 35.7MB on my iPad. As for what’s included in this latest beta, it’s likely just some bug fixes, as Apple is working to make sure that iOS 9.3 is ready for public consumption.

iOS 9.3 itself will be a relatively big update considering that it’s an x.1 update. For example, Night Shift is a major new feature that will automatically turn your device’s display warmer at night, making it easier on your eyes and hopefully making it easier for you to fall asleep. Also included are updated Health and Notes apps, added 3D Touch functionality for Apple’s own iOS apps, and multi-user support for education users.

Apple hasn’t announced when it’ll push iOS 9.3 to the public. The company is rumored to be hosting an event on March 21, and if that’s true, that’s likely when we’ll see the public iOS 9.3 push, too.

Apple today also released watchOS 2.2 beta 6.
