Changed
All Minecraft:structures
Now hardcoded into world generation.
General
The overworld now uses the multi-noise biome source type.
Terrain generation is now independent from biomes, with biomes adapting to whatever terrain they happen to generate throughout.
This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation.
For example, forests and deserts could form up on a hill without needing a special biome just for that purpose.
This additionally allows for smoother transitions between biomes.
Terrain is now smoother and more extreme.
Bedrock layers generate dependent on the world seed now.
New random number generator is used for Overworld generation.
