 * **Breaking changes**
 
 * **Additions**
+  * `BoneFollower` and `BoneFollowerGraphic` now provide an additional `Follow Parent World Scale` parameter to allow following simple scale of parent bones (rotated/skewed scale can't be supported). 
+  * `SpineAtlasAsset.CreateRuntimeInstance` methods now provide an optional `newCustomTextureLoader` parameter (defaults to `null`) which can be set to e.g. `(a) => new YourCustomTextureLoader(a)` to use your own `TextureLoader` subclass instead of `MaterialsTextureLoader`.
 
 * **Changes of default values**
