Apple Seeds Fourth Beta of iOS 10.3 to Developers and Public Beta Testers

Apple today seeded the fourth beta of an upcoming iOS 10.3 update to developers, one week after seeding the third beta of iOS 10.3 and more than two months after the release of iOS 10.2, the last major update to the iOS 10 operating system.

Registered developers can download the fourth iOS 10.3 beta from the Apple Developer Center or over-the-air with the proper configuration profile installed.

iOS 10.3 is a major update, introducing several new features and changes to the iOS 10 operating system. The biggest new consumer-facing feature is "Find My AirPods," which is designed to help AirPods owners locate a lost earphone. Find My AirPods records the last known location of when an AirPod was connected to an iOS device via Bluetooth and can play a sound on a lost AirPod.

Apple's latest update also introduces a new Apple File System (APFS), installed when an iOS device is updated to iOS 10.3. APFS is optimized for flash/SSD storage and includes features like strong encryption.

Apple plans to introduce some App Store changes in iOS 10.3, allowing developers to respond to customer reviews for the first time. iOS users are also able to label reviews in the App Store as "Helpful" or "Not Helpful," which should help surface the most relevant review content.

Also new in iOS 10.3 is a redesigned app open/close animation, an Apple ID profile in Settings, a better breakdown of iCloud storage usage, warnings about outdated apps that won't work with future versions of iOS, HomeKit support for programmable light switches, improvements to SiriKit (bill paying, bill status, and scheduling future rides), CarPlay interface improvements, iCloud analytics options, and more.

Update: Apple has now seeded the fourth iOS 10.3 beta to public testers as well.
