Apple has released Apple TV Software Update 2.3.1. Little is known about the update except that third-party hacks such as boxee unsurprisingly go missing post-update, as usual.

The Apple TV 2.3.1 update is available directly to the Apple TV and won’t appear in your computer’s Software Update application, or in the Apple Downloads web site.

Your Apple TV will update based on your automatic update settings or you can perform manual software update by navigating to Settings>General>About>Update Software.
