Dataminer 'OatmealDome' mentions on social media how there are some other things going on behind-the-scene in this latest update:
"Version 20.3.0 was released. The web browser was updated, and at least one of the changes made appears to be a security-related bug fix. There were no other updates on Switch 1."
Alongside this update, Nintendo has also released a new game for the SNES digital library today, and it makes use of mouse support (including the Joy-Con 2's mouse mode). Nintendo also added mouse support to a few other games in the same library, as well as adding the ability to remap buttons in the SNES app, bringing it in line with the functionality of the N64 and GameCube apps.
Additionally, Nintendo is kicking off its Switch Online Playtest today in select locations. You can find out more about this in our previous coverage.
