After a surprise update in September, Nintendo has today rolled out Version 4.0.1 of Mario Kart 8 Deluxe.

This update, as you might have already worked out, is a lot less exciting. It basically addresses some issues with multiple fixes. If anything else significant about this latest update is discovered, we'll provide an update.

For now, here's the full rundown, courtesy of Nintendo's official support page:

• Fixed an issue where players could not select a user who is registered to the system when playing with two players for Online Play and Wireless Play.
• Fixed an issue where some of the Star Bits would not be displayed when driving on Wii Rainbow Road on Nintendo Switch 2.
