Apple on Wednesday night released an update to its Apple TV set top box software.
The Apple TV Software Update 2.3 makes four changes, as detailed on the “About Apple TV software updates” support page. It adds to the Apple TV the ability to stream music to Airport Express-connected speakers or other Apple TVs via AirTunes; to learn third-party remote controls and use them in addition to the Apple Remote; to display iTunes playlists containing movies, TV shows, podcasts, and music videos; and support for volume control in Music.
To download the free update, you can navigate to Settings > General > Update Software on your Apple TV.
The Apple TV, which sells for $229 for the 40GB model and $329 for the 160GB model, first went on sale in March 2007. Since then, Apple has issued software updates to add many new features, including YouTube viewing and the ability to directly rent or buy movies, and purchase TV show, from the Apple TV itself.
