I` new here and don`t understand much.I just got the Wii U and the only thing I did to it was try to play Mario Kart 8 which updated me to 4.1.Then I tried to use Netflix and Youtube and before I could use them for the first time it asked me to update and I was for if I should do that or not.I`m going to install Homebrew today and I guest I have to update to 5.0 in order to use those apps.Thanks.
