Version 0.3.8 - 2015-4-7

  1. Issue39 MVEL is not enough to discriminate transitions
  2. Issue40 java.util.NoSuchElementException unregistering a TransitionEndListener
  3. Issue41 POM creates some problem when building
  4. Issue42 Javadoc errors prevented the javadoc jar file to be created
  5. [Breaking Change] Correct typo in StateMachineData
  6. Save start context with state machine data

Version 0.3.7 - 2015-1-28

  1. Issue 31 - Crash on starting FSM with action attached to entering initial state
  2. Issue 33 - Deep History Improvement

Version 0.3.6 - 2014-12-26

  1. Fix crash on creating state machine builder on Android

Version 0.3.5 - 2014-12-23

  1. Fix hierarchical state machine transition incorrectly
    state D, state E and its child state E1, when state D->E1, the expected behavior would be "leftD.transitD2E1.enterE.enterE1"
  2. Fix serval typos and add a test case about nested hierarchy state transition issue

Version 0.3.4 - 2014-7-18

  1. Remove deprecated class StringConverter, StateMachineProvider
  2. Simplify state machine builder fluent API - support multiple transition build
  3. StateMachineBuilder.defineNoInitSequentialStatesOn allows to define sequential states without initial state
  4. Issue 18 - Add sample code for how to implement decision state
  5. Issue 20 - Add OSGI support

Version 0.3.3 - 2014-7-6

  1. Support remote monitor and configure state machine instance
  2. Rename state machine configuration methods
  3. Update project dependency Guava version 16.0.1
  4. Fixed Issue 16 - timed state behaves strangely when timeInterval = 0
  5. Fixed Issue 17 - nested states and internal transitions do not work together well

Version 0.3.1 - 2014-3-12

  1. Fixed Issue 14 - Event fired against wrong state machine when FSMs collaborate

Version 0.3.1 - 2014-3-4

  1. Fix action execution position bug
  2. Support custom listener order and fix listener order caused issue
  3. Support fire event immediately, StateMachine.fireImmediate
  4. Fix state machine initial get current state issue
  5. Support method extension from fluent API and annotation

Version 0.3.0 - 2014-2-21

  1. Remove deprecated state machine intercepter classes
  2. Deprecate StateMachineProvider
  3. Support postConstruct after state machine initialized
  4. Remove deprecated exception handling method in AbstractStateMachine
  5. Add API StateMachine.canAccept(E event)
  6. Improve state machine create exception handling
  7. Breaking Change: Reimplement StateMachinConfiguration to simplify its usage
  8. More easy way to enable state machine logger by set state machine debug configure to true
  9. Allow configuration to be set on state machine builder
  10. Make both StateMachineData.Reader and StateMachineData.Writer serializable

Version 0.2.9 - 2014-2-19

  1. Support state machine behavior configuration
  2. Breaking Change: Removed tedious state machine constructor from AbstractStateMachine. Please remove extended constructor in your state machine implementation class.

Version 0.2.8 - 2014-2-17

  1. Action execution bug fixed. State exit actions(both sync/async) should be all executed successfully then begin transition actions, so as the state entry actions.
  2. Add debug loggings while action execution.

Version 0.2.7 - 2014-2-13

  1. Remove deprecated StateMachineWithoutContext Class and related artifacts
  2. Remove deprecated OnActionExecute annotation
  3. Support state machine data serialize/deserialize by ObjectSerializableSupport
  4. Add API StateMachine.getLastException
  5. Deprecate AbstractStateMachine.afterTransitionCausedException(TransitionException e, ...)

Version 0.2.6 - 2014-2-9

  1. Fix bugs around linked state feature
  2. Support timeout for asynchronized action
  3. Improve state transition performance [Issue 11][11] (Thanks to Jeremy)
  4. Add StateMachinePerformanceMonitor to help analysing performance issue
  5. Fix data correctness issues including test event, data isolation during transition and so on
  6. Implement State Machine Importer feature
  7. Add API ImmutableState.getAcceptableEvents()
  8. Add API StateMachine.exportXMLDefinition(boolean) to simplify state machine export usage
  9. Remove UntypedStateMachineBuilder.newUntypedStateMachine(Object, Class) method
  10. Deprecate AbstractCondition, replaced with AnonymousCondition
  11. Deprecate AnonymousUntypedAction, replaced with UntypedAnonymousAction

Version 0.2.5 - 2014-1-19

  1. Support asynchronized method call execution
