Following the release of iTunes 11, Apple has issued an update to their Apple TV products, adding support for iTunes Up Next and a few performance and stability improvements with the iTunes Store, AirPlay, Netflix, iTunes Match, and wired Ethernet connections.
With Up Next, users can see upcoming songs when playing music on your Apple TV. Add new songs and edit what’s queued with the Apple TV remote or the Remote app.
The v5.1.1 firmware update is available now for download and its compatible with the second- and third-generation Apple TV. To run the update, head into the Settings menu on your device and select General, then go into Update Software.
