  variable conditions.
- Implemented issue #13204: Implement ezcWorkflowConditionInArray.
- Fixed issue #13467: Workflow Visualization missed end node.

- Implemented issue #12694: Replace reflection test for class type with SPL
  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.


1.1 - Monday 17 December 2007
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Added explicit calls to __toString() for PHP 5.1 compatiblity.
- Changed default value for the ezcWorkflowExecutionListener::notify() method's
  $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.
- Implemented issue #11003: Add ELSE option to exclusive choice.
