Apple today released tvOS 18.3.1, the newest version of the tvOS 18 operating system that came out in September. tvOS 18.3.1 comes almost two months after the release of tvOS 18.3, and it is only available for the third-generation Apple TV 4K. Other ‌Apple TV‌ models will not have an update available.

tvOS 18.3.1 can be downloaded using the Settings app on the ‌‌Apple TV‌‌. Open up Settings and go to System > Software Update to get the new software. ‌‌Apple TV‌‌ owners who have automatic software updates activated will be upgraded to tvOS 18.3.1 automatically.

Apple shares full release notes for tvOS in its tvOS support document, which is updated after each new version of tvOS comes out. Today's update addresses an issue that could prevent playback of some streaming content on the third-generation ‌Apple TV‌ 4K.

Update: This article has been updated to note that the tvOS 18.3.1 software is only available for the third-generation ‌Apple TV‌ 4K.

Shame they didn’t take as much care over the content of the article by reading and reporting on the release notes.
