- Vertices are no longer stored on RegionAttachment. The vertices are temporary state, not part of RegionAttachment's persistent state like UVs and offset.
- AtlasPage and RegionAttachment "texture" field is renamed to "rendererObject". This is a better name as it may not be a texture.
- AtlasAttachmentLoader uses the AtlasRegion as the rendererObject. This enables a renderer to use region information if needed. The page rendererObject is still available.
- Better "enum" look up for AS3.
- Unity4 example doesn't use a compressed material.
There are no longer separate animation files, they are now inside the skeleton file. This means there is just one file to manage, which is cleaner. Now that animations are stored in SkeletonData, they can be looked up by name which leads to cleaner runtime APIs.
cocos2d and cocos2d-x runtimes got a cleaner ObjC/C++ API.
