Does anyone know if the new generator is used on unexplored parts of previous save games?

  Yes! This update goes so far as to blend chunks around the seams, and will fill out the new cave generation at the bottom of your existing world, replacing the bedrock with deepslate. I'm itching to dive in again once the holidays settle down

  Also, you can use mcaselector to delete the parts of your old saved games where you haven't built anything and let them regen with the 1.18 algo. I just did that with a save and the new terrain smoothly blended in with the old.

  Yes, and not just unexplored areas, but even underneath previously explored areas in the new space created between Y=0 and Y=-64.
