Apple today released a new tvOS update, tvOS 16.3.1. The update comes two weeks following the tvOS 16.3 update.
The tvOS 16.3.1 update can be downloaded via the Settings app on the Apple TV by going to “System” -> “Software Update.” If you have automatic software updates turned on your Apple TV will be upgraded to tvOS 16.3.1 automatically.
The update brings “general performance and stability improvements.” So, Apple TV users have that going for them, which is nice.
Apple’s dedicated tvOS support document is updated after each new iteration of tvOS.
