Quick update came out this morning which updates the Nintendo Wii menu to 3.2. The update only adds a minor feature to the Disc Channel. Once a game disc has been loaded into the console with an update on it, there will be a notification streaming across the Disc Channel, similar to the way the Wii Shop Channel streams release information for Virtual Console games.
Rumors were abound that it might disable the Twilight Princess hack, but alas they are false. Rejoice by continuing to play your favorite game Tetris!
