Nintendo Switch firmware update 13.2.1 released, Atmosphere updated to 1.2.6
Mere hours after Pokémon Legends Arceus was leaked online, a new Nintendo Switch update quietly released. As usual, the menu of the day is as expected, with version 13.2.1 adding nothing but stability. You'll want to refrain from updating if you're running CFW until more is known about this software update.
