    * **Two color tinting** is currently supported via extra UV2 and UV3 mesh vertex streams. To use Two color tinting, you need to:
      * switch on "Tint Black" under "Advanced...",
      * use the new `Spine/Skeleton Tint Black` shader, or your own shader that treats the UV2 and UV3 streams similarly.
-   * **Clipping** is now supported. The SkeletonAnimation switches to slightly slower mesh generation code when clipping so limit your use of `ClippingAttachment`s when using on large numbers of skeletons.
- * **SkeletonRenderer.initialFlip** Spine components such as SkeletonRenderer, SkeletonAnimation, SkeletonAnimator now has `initialFlipX` and `initialFlipY` fields which are also visible in the inspector under "Advanced...". It will allow you to set and preview a starting flip value for your skeleton component. This is applied immediately after the internal skeleton object is instantiated.

  * **[SpineAttribute] Improvements** 
    * **Icons have been added to SpineAttributeDrawers**. This should make your default inspectors easier to understand at a glance.
    * **Added Constraint Attributes** You can now use `[SpineIkConstraint]` `[SpineTransformConstraint]` `[SpinePathConstraint]`

  * **AttachmentTools source material**. `AttachmentTools` methods can now accept a `sourceMaterial` argument to copy material properties from.
  * **AttachmentTools Skin Extensions**. Using AttachmentTools, you can now add entries by slot name by also providing a skeleton argument. Also `Append(Skin)`, `RemoveAttachment` and `Clear` have been added.
  * **BoneFollower and SkeletonUtilityBone Add RigidBody Button**. The BoneFollower and SkeletonUtilityBone component inspectors will now offer to add a `Rigidbody` or `Rigidbody2D` if it detects a collider of the appropriate type. Having a rigidbody on a moving transform with a collider fits better with the Unity physics systems and prevents excess calculations. It will not detect colliders on child objects so you have to add Rigidbody components manually accordingly.
+ * **SkeletonRenderer.OnPostProcessVertices** is a new callback that gives you a reference to the MeshGenerator after it has generated a mesh from the current skeleton pose. You can access `meshGenerator.VertexBuffer` or `meshGenerator.ColorBuffer` to modify these before they get pushed into the UnityEngine.Mesh for rendering. This can be useful for non-shader vertex effects.
  * **Examples**
    * **Examples now use properties**. The code in the example scripts have been switched over to using properties instead of fields to encourage their use for consistency. This is in anticipation of both users who want to move the Spine folders to the Unity Plugins folder (compiled as a different assembly), and of Unity 2017's ability to manually define different assemblies for shorter compilation times.
    * **Mix And Match**. The mix-and-match example scene, code and data have been updated to reflect the current recommended setup for animation-compatible custom equip systems The underlying API has changed since 3.5 and the new API calls in MixAndMatch.cs is recommended. Documentation is in progress.

      * Render settings in `SkeletonGraphic` can now be accessed under `SkeletonGraphic.MeshGenerator.settings`. This is visible in the SkeletonGraphic inspector as `Advanced...`
      * We will continue to bundle the unitypackage with the empty .cs files of deprecated classes until Spine 3.7 to ensure the upgrade process does not break.
    * The [SpineAttachment(slotField:)] optional parameter found property value now acts as a Find(slotName) argument rather than Contains(slotName).
-   * `SkeletonAnimator` now has autoreset set to true by default. Old prefabs and scene values will have been serialized to whatever value it was previously. This change only applies to new instances of SkeletonAnimator.
+   * `SkeletonAnimator` now uses a `SkeletonAnimator.MecanimTranslator` class to translate an Animator's Mecanim State Machine into skeleton poses. This makes code reuse possible for a Mecanim version of SkeletonGraphic.
+   * `SkeletonAnimator` `autoreset` and the `mixModes` array are now a part of SkeletonAnimator's MecanimTranslator `.Translator`. `autoReset` is set to true by default. Old prefabs and scene objects with Skeleton Animator may no longer have correct values set.
    * Warnings and conditionals checking for specific Unity 5.2-and-below incompatibility have been removed.
