Apple has been seeding betas of iOS 10.3.3 for weeks, and now the fourth version is now available. Also tvOS 10.2 for Apple TV. iOS 10.3.3 beta 4 (build number 14G5053a) and tvOS 10.2.2 beta 4 (build number 14W5751b) are now available to Apple’s registered developers and members of the Apple Developer Program through Dev Center.
Both iOS 10.3.3 and tvOS 10.2.2 are bug-fix releases with no new user-facing features. They’re probably the last point updates as Apple is currently beta-testing the next major versions of its platforms: iOS 11, watchOS 4, macOS High Sierra and tvOS 11.
