 * Removed dependency on `RHI`, `RenderCore`, and `ShaderCore`.
 * Re-importing atlases and their textures now works consistently in all situations.
 * Added mix-and-match example to demonstrate the new Skin API.
+* Materials on `SkeletonRendererComponent` are now blueprint read and writeable. This allows setting dynamic material instances at runtime

 		by e.g. the LWRP renderer, leading to incorrect draw order (e.g. "A1 B A2" changed to "A1A2 B").
 		You can leave this parameter disabled when everything is drawn correctly to save the additional performance cost.
   * **Additional Timeline features.** SpineAnimationStateClip now provides a `Speed Multiplier`, a start time offset parameter `Clip In`, support for blending successive animations by overlapping tracks. An additional `Use Blend Duration` parameter *(defaults to true)* allows for automatic synchronisation of MixDuration with the current overlap blend duration. An additional Spine preferences parameter `Use Blend Duration` has been added which can be disabled to default to the previous behaviour before this update.
+  * Additional `SpriteMask and RectMask2D` example scene added for demonstration of mask setup and interaction.
 
 * **Changes of default values**
   * `SkeletonMecanim`'s `Layer Mix Mode` now defaults to `MixMode.MixNext` instead of `MixMode.MixAlways`.
