Nintendo 3DS Update 7.0.0-13 now available.
I'm still waiting for my system to update, it keeps returning an error, but it is available. My guess is the servers are being bogged with a lot of traffic from people eager to link the 3DS and Wii U eShop wallets as well as get Miiverse on the 3DS. Anyway, I don't have really in depth info on this new update aside from the eShop wallet link and 3DS Miiverse, but check out the link below and enjoy the new update :)

If I spelled something wrong, I'll just blame it on auto-correct :D
