Fixes unexpected security holes
In parallel with the iOS 4.2.1 update, which became available at 10AM Pacific time, Apple has released the Apple TV 4.1 firmware. As anticipated, the upgrade primarily adds support for AirPlay, the technology which lets iOS devices stream music, photos and videos to the set-top. Also included is VoiceOver support, which for the visually impaired reads menu and content descriptions out loud.
The speed of voice playback can be changed in the Settings menu. There users can also choose to enable password protection for AirPlay, or disable the function entirely. Unexpected in the update are two security fixes: one for vulnerabilities in FreeType, and another for holes in libpng.
The v4.1 update can only be downloaded from an Apple TV with an active Internet connection.
