Wednesday evening, Apple released the final version ofiOS 10.3.3 for all the iPhone, iPad and iPod Touch compatible. As a reminder, the first beta was made available to developers in May.
As is very often the case with minor updates, Apple has not shared a changelog. With this iOS 10.3.3 firmware, the Cupertino company only corrected bugs encountered by users. If you want to upgrade your iDevice, go to Settings> General> Software update.
At the same time, Apple has put online macOS 10.12.6 for Macs, tvOS 10.2.2 (build 14W756) for the latest generation Apple TV and watchOS 3.2.3 (build 14V753) for Apple Watch.
These three updates, also minor, can be downloaded from the tab Updates from the Mac App Store (for macOS 10.12.6), in the Apple TV 4 settings (for tvOS 10.2.2) and from the Apple Watch app on iPhone (for watchOS 3.2.3).
