    • Deepslate and the bedrock layer currently don't generate due to a bug.[2]
  • Large biomes and amplified worlds now have an upgrade path, and retain more of their characteristics when upgraded to the new terrain system.

    • The "Realms Notifications" option has been moved to this screen.
    • Contains the new "Allow Server Listings" option.
