Apple has released tvOS 27, a significant update for its streaming box, but it will only run on two specific models of the Apple TV 4K released in 2021 and 2022.

• Key improvements include apps launching up to 30% faster, rebuilt Podcasts and Apple Music apps with enhanced features like Hi-Res Lossless support, and new subtitle generation capabilities.
• The update excludes older models, the Apple TV HD (2015) and the first Apple TV 4K (2017), marking the first time an Apple TV model has been left behind on a tvOS release.
• Notable new features include the ability to update Apple TV via the Home app and on-device subtitle generation, though the latter is restricted to English in the US and Canada on the 2022 Apple TV 4K model.
