If you’re a member of Apple’s public beta program, you’ve now got some new software to test out.

Apple is now pushing iOS 9.3 Public Beta 2 to members of the Apple Beta Software Program. The update, which rolled out to iOS developers earlier this week, adds a Control Center button for Night Shift. This makes it easy to toggle the feature on and off. When enabled, Night Shift will slowly shift your device’s display to a warmer, more yellow hue that’s meant to be easier on your eyes when you use your iOS device at night.

While Night Shift is a big new feature of iOS 9.3, there are other notable tweaks. Those include improvements to the Health and CarPlay apps, the ability to lock Notes with Touch ID, support for pairing multiple Apple Watches to a single iPhone, and education features like multi-user support.

If you’re in the Apple Beta Software Program, you can get iOS 9.3 Public Beta 2 by going into Settings > General > Software Update. There’s no word when Apple might roll iOS 9.3 out to the public, but Apple is rumored to be prepping announcements for the week of March 14, so we could see a public iOS 9.3 rollout then.
