Apple has just released a firmware update for Apple TV. The latest update is version 4.4.4 (9A406a).
Nothing major to report yet other than a few bug fixes. You can quickly update your Apple TV by doing the following:
1.Select Settings >General using your Apple Remote.
2.Click Update Software. At this time your Apple TV checks to see if an update is available and a download message should appear if an update is available.
3. Click Download and Install to start the download process. It’s all very quick and easy.
Alternatively, you can go to the direct download and install if manually, but that’s kind of a pain: Here.
