For normal players:
- 1.21.5: Added leaf litter, wildflowers, cactus flowers, bushes, firefly bushes, and dry grass.
- Added 3 new wildflower colors, in addition to the vanilla yellow/white ones.
- Fixed pale netherrack textures in old MC versions. Again.
- LOD rendering now has fog.

For data pack developers:
- Ores (and possibly other things that map blocks to other blocks) can now use tags for the block to map from.
- Fixed being unable to use wood palettes in overriders.
- Added nullable casting syntax:
Type?(expression)casts expression to Type, or evaluates to null if the expression cannot be cast. - Improved error reporting when failing to compile column values.

- This will retroactively apply to existing config files.
