Apple gave its Apple TV set-top box an internal overhaul Friday, issuing a software update that adds a few new features to the device. Arriving two days after AllThingsD predicted it would, the new firmware brings with it a bunch of enhancements. Among new features included in Apple TV 6.0: Support for iTunes Radio and purchases from the iTunes Music Store, the ability to view videos and photos from a shared photo stream, and AirPlay From iCloud, an upgrade to Apple’s AirPlay wireless-streaming software that allows people who have purchased content from Apple’s iTunes store to play that same content on other Apple TVs. Friday’supdate to Apple TV follows the release of iOS 7, the latest version of Apple’s mobile operating system earlier this week; there is continued speculation about new Apple TV hardware.
