WorldWeaver: New Dawn

Features

• Added the common SOIL surface tag API
• Added the pottable datapack registry API
• Added support for seeded vertical cave-biome deciders
• Added a shared helper for double/tall plants that drop with any tool
• Added common infrastructure for BetterEnd and BetterNether plant survival tags

Changes

• Unified soil handling for surface rules and plant placement
• Added datapack-driven registration of pottable plants and soils
• Added support for vertical cave-biome selection using a stable world seed
• Exposed common APIs for flower-pot contents and synchronized potted block data
• Improved compatibility between loader-specific biome and worldgen implementations
• Moved shared plant-loot behavior into WorldWeaver instead of duplicating it in mods
• Made library datagen opt-in during normal builds

Fixes

• Fixed tall plants not dropping when harvested with an arbitrary tool
• Fixed missing common soil support in BetterEnd and BetterNether worldgen
• Fixed pottable plants and soils requiring hardcoded registry lookups
• Fixed cave-biome deciders producing inconsistent results between chunks
• Fixed library datagen being triggered unintentionally by regular compilation
• Fixed missing shared APIs required by the final flower-pot implementation
  
  

  Compatibility note

  The vertical cave-biome decider API and pottable registry API are present in 1.21.1, but BetterEnd’s experimental WorldCarver pipeline remains disabled there. The stable legacy cave generator is still active.
