What can I do?
The new YouTube plugin for ATV2 allows for browsing of popular videos as well as searching for videos, channels, users, or playlists. We're also working on a few other neat options for subsequent releases, so be sure to keep your eyes peeled for updates.
How do I update?
Due to some required behind-the-scenes changes, updating to 2.6 will require re-running the aTV Flash (black) installer from a Mac or PC. Once updated, future releases can be installed through the native Apple TV menus as before. Links for the latest version can be found in your account under the Downloads tab.
