Apple hardly mentioned Apple TV during the WWDC keynote, but a beta version of iOS 7 for the device went live right after the keynote for registered developers. The update doesn’t have the UI overhaul seen in other iOS devices, but it does include iTunes Radio and a few other changes.
Apple calls it the Apple TV Software Update 5.4, and has included support for its new music streaming service called iTunes Radio. Just like on other iOS 7 devices, iTunes Radio will be free and ad-supported on Apple TV.
The other major change noticed is the addition of Conference Room Display mode, where the device displays simple instructions to wirelessly send what’s on an iOS device to an Apple TV via AirPlay.
