v2.305:

Increased Nutrition of Crystal Flowers in the Propane Lakes biome, since they are now trees and if Thrumbos try to feed on them they get hungry faster than they can eat the flower

v2.304:

Adjusted core sample drill to be 2x the speed of the vanilla drill (was 10x)
Fixed a nasty bug where reloading the map on a vanilla biome with the core sample drill would mess up graphic generation on the map (you may get an error on next loading of the map, and the previously placed drill may disappear. Just ignore the error and keep on. You can use dev mod to spawn a new drill to avoid losing the materials)

v2.303:

Added the Core Sample Drill, a buildings that allows you to mine the 5 vanilla rock types from any biome. It requires Deep Drilling and Advanced Fabrication, and its cost is quite high. This is provided to be able to finish some Monument Quests which ask for vanilla rock types in biomes that just don't have them.
Added Doors Expanded compatibility

Removed Pyroclastic Conflagration biome from generating, it was left over from testing
