Several days ago, Nintendo updated 3ds to a new system version v8.1.0-19, it’s a patch for the latest version v8.1.0-18 for further system stability and enhancing user experience!

Nintendo official website notification about the update:

Added support for Nintendo Network ID:

Users can now create a Nintendo Network ID on the Nintendo 3DS family of systems. Users may either create a new ID or register the same ID they have created for their Wii U system.
Using the same ID on both the Nintendo 3DS and Wii U systems will allow users to combine their Nintendo eShop balances and Wish Lists. A Nintendo Network ID will now be required to download free content, including game demos, from Nintendo eShop.

Added support for Miiverse™:
Now available for Nintendo 3DS, Miiverse is an online social hub that lets users connect with other players around the world via their Mii characters. Users can view posts from their Nintendo 3DS, Wii U system, or online via computer or mobile device. Nintendo 3DS users can post illustrations or comments by signing in to Miiverse with their Network ID.
