Nintendo today (April 19) pushed the 14.1.1 update for the Switch host, without adding substantive content, only fixing some problems and improving system stability. Switch players with online requirements will need to update their systems to use the online features.
Switch’s last major firmware update was version 14.0.0 in March, with the addition of a “grouping” feature that allows players to create groups on Switch to schedule and manage game software, creating up to 100 groups of up to 200 games/software per group.
