## Regions Unexplored 0.6: The Next Chapter This is the first beta for RU 0.6, the next major update for the mod. 0.6 is the first major update pioneered by me (Apollo) as I've taken over from the original dev UHQ. **Biomes** - Made significant changes / improvements to the following biomes: - Ashen Woodlands (less clutter, more variation, better water color) - Autumnal Maple Forest (better leaf litter placement) - Bamboo Forest (varying tree density, can get pretty dark in some places) - Chalk Cliffs (no chalk grass blocks on steep cliffs, less dirt/stone breaking through) - Highland Fields (less flower/rock noise) - Joshua Desert (better surface blocks, less cluttered grass) - Outback (better surface blocks) - Pumpkin Fields (less pumpkin clutter) - Redwoods (varying tree density, more foliage, more tree height variation) - Scorched Caves (less basalt leaking into structures like Ancient Cities and Trial Chambers) - Rewrote the biome placement system, replacing the Terrablender dependency with Blueprint. - Blueprint is **temporary** and will be replaced with Lithostitched in the full 0.6 release! - Added Lithostitched as a dependency for some extra worldgen features, and eventually will be the only non-Fabric API library RU uses. - Trial Chambers now spawn in RU biomes. - Shipwrecks now have a chance of generating with RU wood blocks. **Blocks & Items** - Most RU blocks and items can now be found in vanilla item tabs in addition to the RU-dedicated tab. - Merged Medium Grass and Stone Bud into a single block, Grass Sprouts. - Renamed several blocks in preparation for support of future versions. - Cactus Flower -> Saguaro Cactus Flower - [Prefix] Leaf Pile -> [Prefix] Leaf Litter - Fixed Peat Grass Block and Silt Grass Block breaking particle textures being tinted weirdly. **Particles & Sounds** - Added leaf particles to most custom leaves. Some such as Joshua and Brimwood are excluded. - By default leaves use the new vanilla leaf ph
