Appears to mostly be updates to the system browser stuff
 
The switch has already had more updates than every other Nintendo system, and the funny thing is it has the least to show for it

The switch updates have never really improved any experience on the system

How did the thing retire and we never even got themes
 
Whoa, too many updates? Nintendo isn't stable. I do think Costello should intervene in Nintendo to reduce the number of updates.

Nintendo really just letting the Switch retire
I got awesome cat treats for you and Nintendo of America headquarter in Redmond would be your place to play.
 
Now we have to see if this new update requires a new Atmosphere or if the previous one will continue to work.

Oh wow, that happened to me with 20.2.0 until someone released a quick fix, so hopefully it will be quick fix instead need to reverse engineer that take 1-2 weeks.
