The latest Nintendo Switch update is out now, but don’t expect a lot of changes or much in the way of anything significant. Version 12.0.3 is out now and it’s another stability patch.
The one-line patch notes state: “General system stability improvements to enhance the user’s experience.”
Your Switch should update automatically the next time it’s connected to the internet. You can check to verify you’re running 12.0.3 to be sure you’re on the latest firmware. Alternatively, you can manually start the update, in case that applies to you.
