While it does not add new characters or tracks, this update focuses on improving the online experience for specific DLC courses:

This patch directly follows the major update, which added significant features that are still central to the game today:

For users utilizing digital backups (NSP/XCI), this update is essential for maintaining compatibility with the latest online lobbies and DLC packs.

Improved invincibility time after crashes based on the driver/vehicle combination and ensured gliders remain open even if struck by lightning while in the air. Technical Information (NSP/XCI)

Added two cups (Rock Cup and Moon Cup) featuring eight courses like Maple Treeway and 3DS Rainbow Road.

Fixed an issue where the image would become "choppy" or experience frame rate drops during online play on this track.
