Atlas

the biome map is now more lenient about the colors you use

you can now include biomes that will be conditionally loaded if their origin datapack or mod is installed (useful for when you want to use a different biome if a certain datapack is installed) (acikek)

cave biomes and noise caves can now spawn in atlas worlds, fully configurably

as a side effect, some of an atlas world can be generated with noise

assorted bug fixes and optimizations
