Apple has released Apple TV Software 2.3.1, the latest update to its HDTV-tethered media player. As a follow-up to version 2.3, the minor update breaks any unauthorized third-party software, such as the media center app Boxee, but no other changes are readily apparent. Reader reports indicate a couple of small bug fixes, however, Apple has yet to update its Apple TV software release notes page to explain what, if anything, has changed. Apple TV Software 2.3.1 is available now via the Update Software selection in the General Settings menu.
Update: Apple has since updated the release notes entry to include Software Update 2.3.1. The Network Test, which sends information about your Internet connection to Apple in order to help improve download performance, is the only new feature listed.
