According to the information you provided, Google has released the first builds of Android TV 14, based on Android 14. However, currently, only emulator builds are available, and the documentation for Android TV 14 is not yet accessible. It seems that Google is retiring Android TV 13 alongside the release of Android TV 14.
A code change titled “don’t recommend Android TV Tiramisu” was merged into the Android Open Source Project (AOSP), indicating that Google is retiring the use of “Tiramisu” as a version in Android TV. This change aims to discourage developers from creating Tiramisu-based images.
Google has reportedly informed Android TV partners that they will no longer certify builds based on Android TV 13, without providing a specific reason for the discontinuation. Instead, Google is focusing more on Android TV 14, which is expected to be a significant release for the platform.
Regarding the OS upgrade requirement for Android TV, Google generally requires manufacturers of retail Android TV/Google TV devices to support two OS upgrades. However, there are a couple of exceptions:
- Retail devices that initially launch with Android TV 11 can directly update to Android TV 14 as their final update.
- Operator Tier devices that launch on Android TV 10 can remain on Android TV 12 as their final release.
The launch windows for Android TV 11 and Android TV 12 will remain unchanged, but devices can stay on Android TV 11 for a longer duration as Google will provide security patch backports throughout 2024.
