Description:

The edge between the old and new world generation is now adjusted when you upgrade a world.
The Priority Updates video setting has been renamed to Chunk Builder.
Reduced the number of flooded caves near river and ocean coastlines.
Aquifer water levels change less often, so you'll more often have larger areas with the same level. This means slightly fewer underground waterfalls and slightly easier underground boat travel. Lava aquifers are also slightly less common.
Restricted big dripleaf placement to clay, grass, dirt, farmland moss, rooted dirt, podzol, and mycelium.
Some internal details of block and fluid ticking have changed to improve save times.
The Chunk Format has been updated.
