Nintendo’s latest 5.0 software update for the Switch console is now available, and it adds a bunch of minor new features. These include new friend suggestions based off your Facebook and Twitter accounts and new user account icon options, including the lovable pink Kirby. (To add more friends, head to your user page and select friend suggestions.)

For a 5.0 update (from the previous 4.1 in December 2017), the added functionalities are pretty incremental. Other additions to 5.0 include the option to filter news from specific channels, downloads made from a PC or smartphone will start downloading sooner (even if your console is in sleep mode), and new notifications for when prepurchased software is ready to play. You can now also add specific games to your whitelist in the Switch Parental Controls app, though any time limit restrictions you have enabled will still apply.
