• Update to 1.21.1!
• Complete rework to the underlying functionality; TFCGenViewer now has an API! Expect more on it in the docs at some point
• Several reworks to certain visualizer types
  • By default, The Biomes VT now shows a lot more biomes to match TFC's expanded biome palette
  • The Inland Height VT has been merged with Biome Altitude, which now shows 7 discrete altitudes from very deep ocean to mountain elevation
  • The Rivers and Mountains VT now has a flat land color, shows hot spot ages, and has a 'sensitivity' option for river positions
  • The Rocks VT now has two options
    • 'At surface': If the preview should be created for the surface rock layer
    • 'Elevation': The y-level the preview should be created for if 'at surface' is turned off
• Add the Köppen Climate Classification visualizer type, which colors land according to its Köppen climate classification
• The mod is now properly server optional! Players can join servers without TFCGV without any issues, though naturally they will not be able to use the visualizer features
• The permissions system has received an overhaul allowing for more fine-grained control of visualizer permissions
• For the moment, the rock editor sub-screen is unimplemented
• The seed button now also puts the seed into the seed text box when clicked

Note: Currently the wiki is pretty barren and only has pages on using the new permission system and the json types used to define colors. More will be added as I have the time
