Nintendo has updated the Switch firmware to version 6.1.0. Don’t worry too much there are only two small changes, including the usual stability updates and fixes an issue “where certain games don’t recognize a Nintendo Switch Online membership for a short time after purchase”.
You’ll also find an update for your Joy-Con controllers which you can find in the settings.
..but, it's on a Game Key Card.
Ever evolving.
A cheap as can (legally) be.
