The release of iOS 10.3.3 official version brings problem fixes and security improvements.
Early this morning, Apple released the last version of iOS 10, system update 10.3.3, which brings problem fixes and security improvements to all devices running iOS 10. IOS 11 is currently under intense development and will be released in the fall, so iOS 10.3.3 is likely to be the last version update for devices that cannot run the iOS 11 system.
Meanwhile, updates have been released today for macOS Sierra 10.12.6, watchOS 3.2.3, and tvOS 10.2.2.
