@@ -182,6 +182,7 @@
   * URP Shaders: Added `Depth Write` property to shaders `Universal Render Pipeline/Spine/Skeleton` and `Universal Render Pipeline/Spine/Skeleton Lit`. Defaults to false to maintain existing behaviour.
   * Added `Animation Update` mode (called `UpdateTiming` in code) `In Late Update` for `SkeletonAnimation`, `SkeletonMecanim` and `SkeletonGraphic`. This allows you to update the `SkeletonMecanim` skeleton in the same frame that the Mecanim Animator updated its state, which happens between `Update` and `LateUpdate`.
   * URP Shaders: Added URP "Blend Mode" shader variants for both URP 3D and URP 2D renderers. They are listed under shader name "Universal Render Pipeline/Spine/Blend Modes/" and "Universal Render Pipeline/2D/Spine/Blend Modes/" respectively.
+  * URP Shaders: Added support for [Tint Black](http://en.esotericsoftware.com/spine-slots#Tint-black) functionality at "Blend Modes" Spine URP shaders (2D and 3D shaders).
 
 * **Breaking changes**
   * Made `SkeletonGraphic.unscaledTime` parameter protected, use the new property `UnscaledTime` instead.

 # spine-haxe
 
 The spine-haxe runtime provides functionality to load, manipulate and render [Spine](http://esotericsoftware.com) skeletal animation data using [Haxe](https://haxe.org/) in combination with [OpenFL](https://www.openfl.org/) and [Lime](https://lime.openfl.org/).
