In September 2025, Nintendo pushed out a new firmware update for both the Switch 2 and the original Switch. Though the update seems minor, it focuses on improving device stability.
The latest version, 20.4.0, was released on September 2nd. According to the official patch notes, the update fixed various issues and enhanced overall operation stability.

Dataminer OatmealDome mentioned that the update included adjustments for the original Switch. Notably, changes were made to controller-handling code and the web browser.
It’s common for gaming systems to receive stability updates. These updates often roll out to ensure smoother gameplay and better performance. In fact, a 2021 report by the Entertainment Software Association highlighted that 70% of gamers value software updates as a key factor in their gaming experience.
While this version appears focused on stability, users may wonder if there are any backward compatibility fixes tied to it. The gaming community often eagerly anticipates news on such updates, especially as new games release.
