Apple has also released tvOS 11.3 today, a relatively minor update for the Apple TV and Apple TV 4K that primarily adds performance and improvements for bug fixes, along with enhancements to Match Content support, automatic mode switching for AirPlay video sessions, and brings automatic frame rate switching to the older fourth-generation Apple TV. Users in Brazil also gain Siri support with the new update, along with access to Apple’s TV app, which has been pushed out in Mexico as well.
