+* Using new object `UV` instead of `Vector2` where it should be used
 
+* Added `Mesh.flipSided` boolean (false by default)
 
+* `CanvasRenderer` was handling UVs at 1,1 as bitmapWidth, bitmapHeight (instead of bitmapWidth - 1, bitmapHeight - 1)
 
+* `ParticleBitmapMaterial.offset` added
 
+* Fixed gap when rendering `Face4` with `MeshBitmapUVMappingMaterial`
