Extent of Current Features
At this time, aside from any new things I've implemented and forgotten to update here, the following features are present:
- From v1.2.0-alpha.1, Biolith supports all four major mod loaders!
- From v2.0.0-alpha.1, biome placement and surface rules can be added via datapacks.
- Place an Overworld, Nether, or End biome at a specified noise point.
- Remove a vanilla/datapack Overworld, Nether, or End biome from all noise points.
- Replace an Overworld, Nether, or End biome entirely or in part.
- Add a sub-biome to an Overworld, Nether, End, or modded biome.
- (End biome placement uses custom noise and is only available in 1.20+.)
- Register custom surface rules.
- Override vanilla surfaces using custom surface builders.
- Fully compatible with TerraBlender and Fabric Biome API biomes.
- Somewhat compatible with BClib (biome placement will be modified by BClib).
- Can place biomes in Modern Beta worlds in 1.2.0-beta.1 (1.20.4 - 1.20.6).
- Can place biomes in Moderner Beta worlds since 3.0.3 (1.21+).
