Minecraft: Wii U Edition got a pretty significant update a while back which introduced the Tumble Mini Game, and another patch has just gone live.

"Patch 12" wasn't pre-announced and 4J Studios hasn't revealed any details on what's included in the update.

Until those details are forthcoming, it's fair to assume that the patch contains bug fixes and other improvements rather than major features.
