Hello, I bought the package of basic IvanOnTech courses around 2-ish years ago and am only now actually completing them. I only have access to the old Ethereum programming 201 course and not the new one (although I did get access to the newest 101 course for some reason).
My question is: what are the major differences between the old and new 201 courses? Is the old one too out-of-date to still be worth completing?
