From what I'm seeing, they're all the same. I've checked all of the trades on stonemasons, librarians, farmers, and all 3 gear smiths, and not a single trade has changed in value or the number of times you can trade per cycle. I have a village with nearly 80 villagers in it and the prices for everything are unchanged.
I did try it again in my creative world with new villagers, and it's doing the new trades. The bookshelf trade on librarians actually got nerfed, it used to be 6 emeralds for a bookshelf and now it's 9, so I'm definitely going to leave all of my old villagers alone and just make a new one.
