Captive Wi-Fi Support Highlights tvOS 15.4

The major addition in the software is support for captive Wi-Fi networks found at places like a hotel. You can use your iPhone or iPad to complete the additional sign-in steps.

Also, in the video player found in the Apple TV app, you can now quickly view a “Up Next” section.

Apple has also revamped the spatial audio controls.

The software should automatically be downloaded to a Apple TV HD or Apple TV 4K.

If you haven’t already enabled automatic updates, you can download the software by heading to Settings > System > Software Updates > Update Software. Right the button to update software is the toggle switch to turn on automatic updates.
