 ## 1.0.2 (current development)
 
 ### UI Enhancements:
-- New tab for world controls
+- New tab "World Controls"
-    - Relocated grid controls, auto reset to this tab
+    - Relocated grid controls and auto reset to this tab
     - Button to generate random walls with perlin noise
-    - Options for starting state, including simple producer and empty state
+    - Button to reset the environment with many randomly generated organisms
-    - Option to not clear walls when resetting
+    - Option to not clear walls on reset
     - Option to pause on total extinction
-- Combined `Movers can rotate` and `Offspring rotate` simulation controls into `Rotation enabled`
+- "Simulation controls" tab renamed to "Evolution Controls"
-- Can now drag view while rendering is off
+- Button to save/load Evolution Controls in a `.json` file
+- Button to randomize the organism in the editor window
+- Can now use drag view tool while rendering is off
+- Reorganized "About" tab and left panel, embedded explanation video
 
 ### Simulation Enhancements:
--
+- New evolution control `Extra Mover Reproduction Cost`, which adds additional food cost for movers to reproduce
+- Combined `Movers can rotate` and `Offspring rotate` evolution controls into `Rotation enabled`
+- Fully max out simulation speed when slider is all the way to the right
 
 ### Bug Fixes:
 - Armor is no longer ignored when checking for clear reproduction space
+- Chart data is now properly loaded/discarded when paused
