Nintendo Enters Switch Maintenance Mode as Switch 2 Looms

Nintendo released Switch system update 21.0.0 with two focused improvements: clearer visual feedback for screen calibration on docked setups and unspecified Notifications system updates. No new features or stability changes were documented. The release reflects Nintendo's established pattern of incremental firmware refinement across the nine-year-old platform, signaling a shift toward maintenance rather than expansion ahead of the Switch 2 launch.
