The latest Nintendo Switch update has arrived, and it's a notable one. Update 6.0 is out now, and it adds the long-awaited Nintendo Switch Online service and its related functionality. Most importantly, you now need a Switch Online membership to play online for many games.

Your Online membership also gets you cloud saves for compatible games, which is nice. Outside of the new online functionality, Update 6.0 adds six new Captain Toad icons (what great timing, huh?), while you can now post up to four screenshots to social media.
