At first, an unity class FiniteStateMachine has been removed. This is a very simple abstract class, so I prepared my class instead of it easily.
Next, BonePose.CurrentAnimation member was renamed to CurrentController. Also CurrentBlendAnimation was renamed to CurrentBlendController. It's possible to replace them by replace command of VS.
Lastly, AnimationEventHandler's sigunature has been changed from AnimationEventHandler(AnimationController sender) to AnimationEventHandler(object sender, EventArgs e). See this.
