Mario Kart 8 Deluxe (Switch): all the updates (latest: Ver. 3.0.5) 22 May 2025 —
The 3.0.3 update represents a pivotal shift in the lifecycle of Mario Kart 8 Deluxe . Following the conclusion of the Booster Course Pass in late 2023, many fans assumed the game was finished. The release of a surprise security patch nearly a year later demonstrates Nintendo's commitment to protecting its massive player base—now exceeding 70 million users—even in the absence of new tracks. While 3.0.3 may lack the "flash" of new racers, its role in preserving the integrity of the definitive racing experience is essential for the game’s longevity.
