Apple has made the second betas of upcoming iOS 11.3 and tvOS 11.3 updates available to public testers. Those in the Beta Software Program can download them from Apple’s website, or via their respective over-the-air update mechanisms.
iOS 11.3 is shaping up to be a significant update, with several new features and improvements. Changes in beta 2 include new App Store and iTunes Store splash screens, new Battery Health feature in Settings, improved AirPlay 2 support, and more.
tvOS 11.3 is much more tame, but still adds a handful of improvements, including support for AirPlay 2 and other iOS 11.3-related features, frame rate switching for Apple TV 4, and automatic mode switching for AirPlay video sessions.
Apple says iOS 11.3 and tvOS 11.3 will be released to the public in the spring.
