This version adds several new options to base terrain generation that vastly improve Terra's capabilities. These options are Slant Palettes and Elevation Equations.
Slant Palettes are Block Palettes to be inserted on slanted terrain. This allows separate blocks to be used on cliffsides/steep hills.
Elevation Equations define a second, high-resolution 2D noise function to pass over terrain a second time. This allows true vertical steps/cliffs to be created.
More info on these new options can be found on the wiki.
This version also improves cave generation, and adds more config options to carvers. Note that this update will break cave parity, but not generation parity.
