You might have to be more careful with your language
The Switch has received a new firmware update of sorts, though it’s not the kind you usually see. You don’t need to reboot your Switch, and the version number hasn’t changed. The only difference is some new words added to the bad words list.
For most, this shouldn’t impact your Switch usage in any substantial way. But, if you’re prone to using naughty language on Nintendo’s latest platform, you might have to be more careful.
