+0.2.0:
+New
+ - Flywheel driven shulker box rendering
+ - Optimize chunk accesses by caching previous result
+ - Further optimize flywheel rendered objects through parallel updates
+Changes
+ - Distant objects are update throttled according to the sequence of prime numbers, smoothing out updates
+ - Rename normalOverlay to debugNormals, make naming consistent across command and config
+Fixes
+ - Fix issue causing modded banner patterns to all have missing textures
+Technical/API
+ - Reorganize, simplify, and document everything in the MaterialManager tree
+ - MaterialManagers associate RenderStates with MaterialGroups
+ - Proper support for rendering in different layers (SOLID, CUTOUT, and TRANSPARENT)
+ - New methods in MaterialManager to accommodate these changes
+ - Deprecate old functions in MaterialManager in favor of new ones using MaterialGroups
+ - InstanceDatas can be transferred to other Instancers via "instance stealing"
+ - Abstraction for models, IModel
+    - Easier to use, and gives Flywheel more freedom to optimize
+    - Buffered models directly consume IModels
+    - Added BlockModel, renders a single block
+    - Added WorldModel, renders many blocks given a world instance
+ - Cuboids can be inverted across Y and Z, used by many vanilla models for some reason
+ - TransformStack scaling
+ - VecBuffer coloring
+ - Add more information to RenderLayerEvent and BeginFrameEvent
+
 0.1.1:
 New
  - Flywheel driven chest and bell rendering, ~20x performance improvement in contrived cases
