- Inspector: String attribute `SpineSkin()` now allows to include `<None>` in the list of parameters. Previously the `includeNone=true` parameter of the `SpineSkin()` attribute defaulted to `true` but was ignored. Now it defaults to `false` and has an effect on the list. Only the Inspector GUI is affected by this behaviour change.
- `SkeletonGraphicRenderTexture` example component: `protected RawImage quadRawImage` was changed to `protected SkeletonSubmeshGraphic quadMaskableGraphic` for a bugfix. This is only relevant for subclasses of `SkeletonGraphicRenderTexture` or when querying the `RawImage` component via e.g. `skeletonGraphicRenderTexture.quad.GetComponent<RawImage>()`.
- Fixed a bug where when Linear color space is used and `PMA vertex colors` enabled, additive slots add a too dark (too transparent) color value. If you want the old incorrect behaviour (darker additive slots) or are not using Linear but Gamma color space, you can comment-out the define `LINEAR_COLOR_SPACE_FIX_ADDITIVE_ALPHA` in `MeshGenerator.cs` to deactivate the fix or just to skip unnecessary instructions.
- Fixed SkeletonRootMotion components ignoring parent bone scale when set by transform constraints. Using applied scale of parent bone now. If you need the old behaviour, comment out the line `#define USE_APPLIED_PARENT_SCALE` in SkeletonRootMotionBase.cs.
- **Changes of default values**
