They did not spend more than two weeks since the last update for Wii U, until now Nintendo has surprised us with this new: 5.1.1 . This update brings nothing interesting , just blocks an exploit with web browser that could have allowed the entrance of the Scene this console. Upgrade? It depends. If we wait to see what promises to exploit this, it is best not update.
