   * Added Spine Preferences setting `Prefabs` - `Optimize Preview Meshes`. When enabled, Spine prefab preview meshes will be removed in a pre-build step to reduce build size. This increases build time as all prefabs in the project will be processed. Defaults to false to not slow down builds substantially every time.
   * Added Spine Preferences setting `Reload SkeletonData after Play`. When enabled, the shared `SkeletonData` of all skeletons in the active scene is reloaded (from the `.json` or `.skel.bytes` file) after exiting play-mode. You can disable this setting to avoid the reloading delay if you can ensure that there are no (accidental) modifications to the shared `SkeletonData` during play-mode (otherwise it would carry over its effect into subsequent plays). Defaults to `true` (the safe setting), which maintains existing behaviour. 
   * Added `SkeletonAnimationMulti` sample component methods `SetActiveSkeleton(int index)` and getter property `SkeletonAnimations` to more easily apply changes at all SkeletonAnimation instances instead of only the active one.
+  * PMA textures now have `sRGB (Color Texture)` disabled by default, the preset template `PMATexturePreset.preset` has been adjusted accordingly. As PMA textures are only allowed with Gamma color space, `sRGB (Color Texture)` shall be disabled to prevent border artifacts when mipmaps are enabled. In Gamma color space having this setting disabled has no drawbacks, only benefits.
  
 * **Breaking changes**
   * Made `SkeletonGraphic.unscaledTime` parameter protected, use the new property `UnscaledTime` instead.
