Changes
Reworked large-scale terrain generation to mimic plate tectonics
- Each continent area will now be bordered by convergent or divergent boundaries
- These may be subduction zones, rift valleys, collisional mountain ranges, and ocean ridges
- Stratovolcanoes are limited to subduction zones, but other varieties of volcano remain independent of tectonics
Oceans
- All ocean biomes made deeper, with trenches extending to y = 0
- Atolls can now be found in tropical oceans and deep oceans
- Removed sand-bar style islands from generation
- Trenches are now found only in subduction zones
- Mid-Ocean ridges occur in the deep ocean
Island Chains
- Volcanic island arcs form in subduction zones
- Barrier islands/barrier reef chains form on the passive margins of continents
Karst Biomes
- Cenotes made larger and can have overhangs
- Tower karsts reworked to be larger with more diverse shapes
Volcano Changes
- New giant stratovolcanoes in a variety of shapes, made of layers of igneous extrusive rocks and tuff
- Stratovolcanoes replace the old cinder cones in mountain biomes
- Cinder Cones now occur in volcanic mountain islands, on shield volcanoes, in canyons, and in rift valleys
Carver Caves
- Made larger and rarer
Coastal Terrace Biomes
- Now generates slightly overhanging cliffs more consistently, instead of occasionally generating perfectly vertically
Rivers
- Large rivers now carve wide river valleys through mountains and other high elevation biomes
General
- Plains made flatter and lower
- Rolling hills made hillier
- Forest soil blending improved
- Make bamboo features less square
Mountains (Inland variants only, oceanic mountains unchanged)
- Generate in more solid ranges (less likely to be interrupted by plateaus etc)
- Generate more ridges and valleys, and fewer isolated peaks
- Made substantially taller
Rocks and Minerals
- Allow igneous intrusive to be present on the surface of volcanic regions
- Allow more metamorphic rocks to be present at the surface of uplift regions
- Allow cinnabar to generate in high-elevation rocks
- Extend the vertical ranges of several other ores to match new mountain heights
- Remove deep ruby ore, and move it to collisional mountains
- Add missing gem ore info to the field guide
