+Version: 0.3.0
+Date: 2020-09-12
+
+  Recipes:
+    - Upgraded geological calculations to a more robust system.
+    - Rederived all chemical ratios.
+
+---------------------------------------------------------------------------------------------------
+Version: 0.2.1
+Date: 2020-07-17
+
+  Technology:
+    - Moved hydrofluoric acid-based Chemical science pack recipe to
+      Fluorine processing tech.
+
+  Recipes:
+    - Changed Chemical science pack to use hydrofluoric acid instead
+      of fluorite, to improve balance with gypsum/calcite.
+
+  Changes:
+    - More code improvements.
+
+---------------------------------------------------------------------------------------------------
+Version: 0.2.0
+Date: 2020-07-16
+
+  Recipes:
+    - Reduced mineral counts from flux recipes by 1/2 for better balance.
+
+  Changes:
+    - Began code overhaul with some non-game-changing code improvements.
