Apple has posted tvOS 16.1 with a new Siri interface and more. It can be downloaded by going to the Settings app on your Apple TV set-top box. Then go to System > Software Update.
Here’s Apple explanation of the new tvOS 16.1 features:
Siri on Apple TV features a complete redesign, and will be able to recognize each user’s voice, so they can easily access their movies, shows, music, games, and apps, and pick up where they left off. By using the Siri Remote and asking “What should I watch?” users can get tailored recommendations.
The more compact design of Siri on Apple TV allows users to quickly view results without leaving the action onscreen.
