According to page 45 of the specification, OnPreparedToRelease() can only be called in state zombie. As the state transitions are finished with asynchronous calls, OnPreparedToRelease() is the call which finishes the state transition to "zombie". Therefore the call must be allowed in states "new enabled", "configured" and "destroyed". "zombie" must be removed from the list. This has been updated for this method.
