Apple today released tvOS 16.3, the third major point update to the tvOS 16 operating system that originally came out in September. Available for the Apple TV 4K and Apple TV HD, tvOS 16.3 comes six weeks after tvOS 16.2, an update that added Apple Music Sing.
The tvOS 16.3 update can be downloaded over the air through the Settings app on the Apple TV by going to System > Software Update. Apple TV owners who have automatic software updates turned on will be upgraded to tvOS 16.3 automatically.
tvOS updates are usually minor in scale, focusing on internal bug fixes and improvements rather than notable outward-facing changes. There is no word as of yet what's included in the tvOS 16.3 update, and no features were found during the beta testing process.
Apple shares information on tvOS releases in its tvOS support document, which is updated after each tvOS launch.
