I compared my 40+ yo blue Book to the one I bought a couple years ago. Things have changed. Personally I would no longer trust my old "tried and true" recipes that family has handed down. I canned for years, grew up with it but rarely can now. While I wouldn't use my instant pot for canning I still have a 22qt and an 8qt stove top that I do use.
