It's time to keep your Nintendo Switch consoles away from siblings, friends, or dogs that might accidentally update them, because there's a new firmware in town. Nintendo has just pushed out an update for system software version 12.0.2, which adds the grand feature of improving the general system stability. Of course, that could mean a variety of things in respect to what's going on under the hood, so wait until trusted sources know more about what's going on in this latest firmware.
[UPDATE] It appears as though there are some issues for those on CFW that have updated. SciresM says an update will be out tomorrow for for Atmosphere that provides 12.0.2 support.
Atmosphere will mostly work, an update is needed for real compatibility (sleep may be broken on mariko, for example).— Michael (@SciresM) May 12, 2021
Expect a full ams support update sometime tomorrow. https://t.co/ZL7AO3PdCX
