v1.3 (1.20.2-1.20.4)

This update contains a breaking API change. The old 'biomes' list is now as single 'biome' string that support biome tags. Additionaly, the old 'custom biomes' implementation has been removed as it now supports dynamic biome checks using macros.

Now uses Macros to remove a lot of previously hardcoded code
Now uses /random, which supports chunk-based seeding (ore gen is now world seeded)
