Upgrading my board from v3.7.6 to 3-8-4_Patch_Level_2 ?
 

I am going to attempt upgrading my board from v3.7.6 to 3-8-4_Patch_Level_2 ? Is this what I want to do? Or, should I go straight to 4.x ? Will I loose anything from my board or arcade?

I don't know if should leave well enough alone or go for it. (And, for what reason?)
I just don't want to loose or break anything :)
Advice would be appriciated from more than one source. You know ?
