The latest Nintendo 5.0 software update for the Switch console is now available, and adds a lot of new minor features. These include new friend suggestions based on your Facebook and Twitter accounts and new user account icon options, including the beloved Kirby Pink. (To add more friends, go 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 quite incremental. Other additions to 5.0 include the option to filter news from specific channels, downloads made from a PC or smart phone will begin downloading before (even if your console is in sleep mode) and new notifications for when the pre-purchased software is ready to play . Now you can also add specific games to your whitelist in the Change Parental Controls application, although all time limit restrictions that you have enabled will apply.
Nintendo also seems to be preparing the Switch system for hardware upgrades with a review of its SoC, as noted by the piracy enthusiast @ SciresM:
If you have a switch, the console usually automatically downloads updates while online, but you can also manually start the update if you wish.
