Apple has released Apple TV Software Update 4.2 for the second-generation Apple TV. According to the new “What’s New” screen, the update includes support for MLB.tv and NBA League Pass streaming, AirPlay video streaming for apps and Safari, new slideshow themes, and Dolby Digital 5.1 surround sound in Netflix movies and TV shows, as well as an improved on-screen keyboard. Apple TV Software Update 4.2 is available now via the device’s software update feature or as a direct download from Apple.
Update: Despite indications in the beta software that Apple would finally synchronize the Apple TV’s Software and iOS Build numbers on 4.3, the official release has the new Software listed as Version 4.2, with an iOS Build of 4.3. We have updated this and the accompanying MLB.tv/NBA League Pass articles to reflect the correct, official version numbering.
