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.
