^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed issue #14451: $workflow->nodes does not return all nodes.
- ezcWorkflowNodeSubWorkflow now passes the correct parent id to a child
  workflow.
- Increased compatibility with stricter MySQL server modes.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed execution of ezcWorkflowNodeFinally nodes.

- ezcWorkflowDefinitionStorageXml can now handle subclasses of
  ezcWorkflowNodeStart, ezcWorkflowNodeEnd, and ezcWorkflowNodeFinally.
- The ezcWorkflow class now implements the Countable interface. count() invoked
  for an ezcWorkflow object will return the number of nodes of the workflow.
- The ezcWorkflowExecution::loadFromVariableHandlers() and
  ezcWorkflowExecution::saveToVariableHandlers() methods now pass the
  ezcWorkflowExecution object to the ezcWorkflowVariableHandler::load() and
  ezcWorkflowVariableHandler::save() methods.


1.3.1 - Monday 09 February 2009
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed ezcWorkflowVisitorVisualization::__toString() for workflow variable
  values with HTML entities.


1.3 - Monday 05 January 2009
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Changed the Loop node to allow more than two incoming and outgoing nodes.


1.3rc1 - Monday 15 December 2008

  function.


1.2alpha1 - Monday 07 April 2008
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Implemented issue #10941: Support for the Cancel Case workflow pattern. The
  execution of a workflow can now be cancelled by either reaching a
  ezcWorkflowNodeCancel node or by calling the cancel() node on an
  ezcWorkflowExecution object. In either case, the execution is immediately
  halted, already activated nodes will not be executed.
- Implemented issue #12404: Separate file i/o from XML processing in
  ezcWorkflowDefinitionStorageXml.
- Implemented a plugin system that allows plugin developers to hook into
  various extension points in the workflow execution engine.
- The visualization visitor can now show the current state of a workflow in
  execution. This includes the highlighting of activated nodes as well as the
  contents of the workflow variables.
- The new execution visualizer plugin (ezcWorkflowExecutionVisualizerPlugin)
  uses the visualization visitor to create visualizations of each step of a
  workflow execution.

  $type argument from self::INFO to ezcWorkflowExecutionListener::INFO to work
  around an issue in PHP 5.1's Reflection API that breaks the test suite.


1.1rc1 - Wednesday 05 December 2007
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1.1alpha1 - Monday 29 October 2007
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Added ezcWorkflowNodeLoop class to conveniently express loops.
- Refactored the XML definition storage:

  - DOM is now used for both the loading and saving of workflows (issue
    #10702).
  - The marshalling of the node configuration is now handled in the individual
    node classes. This makes it possible to have custom node classes handled by
    the XML definition storage.

- Default node configurations are handled better now.
- Implemented issue #10883: Apply comparison conditions to two variables.
- Implemented issue #10918: Error messages when loading invalid XML.
- Implemented issue #10985: Mapping variables between parent and sub workflows.
