In a surprise system update, a number of new features are added to the Nintendo Switch system. The biggest are explained below, and the rest can be found in the changelog at the bottom.

First of all you can now capture 30 seconds of gameplay from selected games (The Legend of Zelda: Breath of the Wild, Mario Kart 8 DeLuxe, ARMS and Splatoon 2). You can capture video by holding the Capture Button on your left Joy-Con. Afterwards you can trim the video down and post it on Twitter or Facebook. While for now it only works with 4 titles, it is expected that we will be able to bombard the internet with videos from other games in the future too.

You can also transfer your user profile and save data to a new system. Both systems need to be linked to the same account however. Unfortunately this means that save data still cannot be stored, only transferred.

Some new user icons are added from The Legend of Zelda: Breath of the Wild and the upcoming Super Mario Odyssey to fancy up your profile. Finally the update makes it possible to pre-purchase certain games on the eShop.

You can find the full changelog below:

General system stability improvements to enhance the user's experience, including:

  • The Nintendo Switch console supports WEP, WPA-PSK(AES), and WPA2-PSK(AES). If your router is using a different security type (e.g. WPA-PSK(TKIP)), you will need to change this security type within your router's settings.
