As you’d expect with most system updates these days, the latest firmware patch for the hybrid/home console offers some system stability improvements, but it also introduces a sorely-needed improvement to the system’s data management suite, too. The new firmware allows you to easily delete update data from software if there isn’t enough room to download and install other data you’re eager to play. This means, essentially, you can remove old patches if you want to download a new patch, making it easier to manage data on the console. You can modify game updates installed on either the internal storage or microSD, too. Check out the full patch notes below: Ver. 12.1.0 (Released July 5, 2021)
Added the following system functionality: If there is not enough space remaining on the system memory (internal storage) or microSD card when downloading game software update data, you can now delete old data for that software, enabling you to download the new data. When deleting the old data, you won’t be able to play the game until the new data has finished downloading. General system stability improvements have been made to enhance the user’s experience.
In terms of what’s next for the console after the Nintendo Switch firmware update 12.1.0, rumors still abound that a new iteration of the Switch hardware is en route at some point soon.
