ok. If you do make a patch, then you cannot simply put the new jarfile up for download. You have to make all the stuff then seperate everything you have done and put it in a download as if you do just put the minecraft 1.9.4 jar up, with patches in then it is file sharing and very illegal and also It is really difficult seperating all the new files you have done. overdone enough?
I see. But I had seen patches done for the other prereleases, if I remember correctly.
