Nintendo has updated the Wii U firmware to 5.5.4

• You thought it was dead, but the Nintendo Wii U lives on. Following an update that initially was just for European regions, the update is also supposedly to be made available in North American and Japan, according to patch notes. However, currently, Nintendo of America's site does not note any new firmware revisions, nor do we know if the update will actually come to non-EU systems. At this point, we have no idea what 5.5.4 changes, besides standard stability. The last time we saw an update for the Wii U was all the way back in September 2018, for version 5.5.3 which was yet another stability update. If you still value using your Wii U, you might want to wait on updating, to see what this changes in terms of homebrew.
