When Nintendo normally releases an update for the Nintendo Switch‘s firmware, it results in a version number change and, at the very least, a handful of changes that had been made confirmed via patch notes. For these updates to finish, the console is required to reboot itself.
Well, Nintendo has decided to release another “rebootless” update tonight. These don’t require the console to reboot, and they generally don’t do anything significant to the firmware. In fact, Nintendo doesn’t even release patch notes for these. That said, you can see a tweet relaying what the rebootless update did change down below.
