* **Breaking Changes**
* **Additions**
* Removed dependency on STL throughout the code base, cutting down on the LOC that need parsing by 66%.
### Cocos2d-x
### SFML
### UE4
* `SpineWidget` now supports the full widget transform, including rendering scale/shear.
* **Breaking changes**: `SpineWidget` no longer has the `Scale` property. Instead the size x/y properties can be used.
