The 5.5 kernel exploit has been privately held for a while now. I could be wrong but I don't think it will be released until it gets patched by Nintendo first which might be a while. Our short term hope right now is Hykem's IOSU exploit which if released, will blow the Wii U hacking scene wide open as it pretty much gives us all the access to the system that we need.im guessing youre talking about no public kernel for 5.5 because there probably is one in the works
