2.0.1

fixes

• LCA handling was broken and resulted in a wrong execution sequence of exit - action - enter
• corrected typos in CHANGELOG.md (this document)

2.0.0

enhanced state switching:

• state machine can now switch from a substate of a sub state machine deep into another submachine. Implementation uses LCA (Least Common Ancestor) - algorithm

re-worked event handling:

• events will be registered by setting target action and guard:

- (void)registerEvent:(TBStateMachineEvent *)event
               target:(id<TBStateMachineNode>)target
               action:(TBStateMachineActionBlock)action
                guard:(TBStateMachineGuardBlock)guard;

• event processing follows RTC-model. The state machine will queue all events it receives until processing of the current event has finished

1.0.0

• updated documentation
• updated API

0.9.0

• initial release
