Important Notes when Upgrading

(2017 October 16) The old AttachmentTools static class called SpriteAtlasAttachmentExtensions was renamed AtlasUtilities. Any methods that were called as statics rather than extension methods must now refer to that new name. Extension method calls will not need any code changes.
(2017 June 11) SkeletonGraphic now allows you to override the mainTexture with a repacked texture using SkeletonGraphic.OverrideTexture.
(2017 May 6) Sprite Shaders: When updating shaders from any source, especially ones that use cginc files, it may be necessary to restart Unity or right-click then choose Reimport All in the project panel so the cginc files are properly reimported. https://forum.unity3d.com/threads/is-there-a-way-to-force-shaders-to-update-when-cginc-files-are-updated.336041/
(2017 May 6) Sprite Shaders: Some files from the older version of the Sprite shaders were removed. delete the whole spine-unity/Modules/Shaders/Sprite subfolder before upgrading to ensure no old unused files are left behind.
(2017 May 6) Sprite Shaders: Updated to the latest source version. Some serialization may have changed. If you used these shaders, do go over your Material assets and make sure they have the correct settings: https://github.com/traggett/UnitySpriteShaders
(2017 Mar 30) You now have the option to disable multi-mixing to get rid of the dipping issue. This can be set with the AnimationState.MultipleMixing bool property. In 3.5, it is enabled by default so updating your runtime will not result in unexpected changes in animation behavior. You can change the code so AnimationState sets the value to false by default to remove unwanted dipping at the cost of multiple mixing. This default may change in 3.6.
(2017 Jan 24) Based on Unity Technology recommendations, whenever SkeletonUtility (or BoundingBoxFollower) generates PolygonColliders based on Spine Bounding Boxes, it will also add a Kinematic Rigidbody2D to that object. This means each of those GameObjects are their own immutable box2D body and cost significantly less computationally to move/animate.
(2016 Nov 28) Some UnityEngine.Sprite.ToRegion methods have been moved to consolidate code. You will need to add using Spine.Unity.Modules.AttachmentTools to your using directives in your code.
(2016 Oct 23) Spine 3.5 The context menu for creating scene objects from the Project view/asset menu is disabled by default because it is not the recommended place for scene objects. You can now instantiate your skeletons by dragging and dropping the SkeletonData asset into the scene view, similar to Unity Sprites. See this topic for more details: http://esotericsoftware.com/forum/New-Feature-Drag-and-Drop-to-instantiate-6789
(2016 Jul 13) Spine 3.4 There were no base runtime feature and serialization changes between 3.3 and 3.4. There is no need to re-export your binaries and jsons if they were exported with Spine 3.3.
(2016 Apr) The sample implementation module called VertexHelperSpineMeshGenerator has been removed. You can find the code here: VertexHelperSpineMeshGenerator.cs
(2016 Apr) The .unitypackage was exported with Text Serialization to improve the example scenes compatibility with version controlled projects (and Unity Collaborate).
(2016 Apr) Spine 3.3 involved some refactoring. If you are upgrading your runtime, it is recommended that you delete your spine-csharp folder before importing the new files. Some redundant/unused files like FfdAttachment.cs and WeightedMeshAttachment.cs may be left over and cause errors. (Because none of the spine-csharp files are Unity components, deleting or replacing it will not break any of your scenes or prefabs.)
(2016 Apr) Most older jsons (especially with meshes) are not compatible with Spine 3.3 and higher. You will need to re-export your skeletons even if you used json. As usual, skeleton binaries are incompatible across Spine editor versions.
(2016 Mar) Spine classes were moved into the Spine.Unity namespace. You will need to update your scripts that use Spine classes. Add using Spine.Unity and/or using Spine.Unity.Modules. Read more here: http://esotericsoftware.com/forum/spine-unity-namespaces-6025
(2016 Mar) Old sample binary files were removed.
(2016 Mar) SharpJson.cs was merged into Json.cs. Please delete SharpJson.cs when upgrading.
