iOS developers, some new beta updates have arrived.

Apple today unleashed iOS 10.3 beta 4 to registered developers. The update can be grabbed over the air by going into Settings > General > Software Update, or by visiting Apple’s Developer Center on the web.

iOS 10.3 beta 4 doesn’t appear to be available to public testers quite yet. If past beta updates are any indication, though, this one should hit public testers in the next couple of days.

The update to iOS 10.3 is a significant one, bringing with it a new feature called Find my AirPods. It is just what it sounds like, helping AirPods owners find their lost earbuds using Bluetooth and sound. The update also adds the Apple File System to iOS, the ability for developers to reply to app reviews, and more.

Apple also released watchOS 3.2 beta 4 to developers today. That update can be installed by going into the Watch app on your iPhone and then selecting General > Software Update.
