Spine 3.4 was just released. Spine is a 2D bone based IK animation system I previously covered in depth here if you are looking for more information. The 3.4 release brings a number of new features including:
- improved transform constraints
- shearing (skew/squash/stretch)
- paths and path constraints (see image to right)
- spine-sfml, cocos2dx and objc now 3.4 compatible
- spine-csharp, unity, xna and monogame all 3.4 compatible
- cocos2d-x v2 runtime deprecated
- new example projects illustrating path functionality
- runtimes for Flash currently in progress
- introduction of Beta versions
