Apple on Tuesday updated its Apple TV software to version 5.0.2 for second and third generation units.

The Apple TV Software Update, released as build 9B830, brings unknown fixes to both the second and third generation set-top media streamers. Apple's support web page has yet to divulge the contents of the update, but a more detailed description should be posted in the near future.

The quick download showed no visible changes to the UI or content meaning that the update may be a fix for backend performance issues or preparation for as-yet unreleased features set to be announced at WWDC next week.
