CHANGELOG
=========

4.3.0
-----

 * Trigger `entered` event for subject entering in the Workflow for the first time
 * Added a context to `Workflow::apply()`. The `MethodMarkingStore` could be used to leverage this feature.
 * Add style to transitions by declaring metadata:
        ```        
        $places = range('a', 'b');
        $transition = new Transition('t1', 'a', 'b');
        $transitions[] = $transition;
        $transitionsMetadata = new \SplObjectStorage();
        $transitionsMetadata[$transition] = [
            'color' => 'Red',
            'arrow_color' => '#00ff00',
        ];
        $inMemoryMetadataStore = new InMemoryMetadataStore([], [], $transitionsMetadata);
        return new Definition($places, $transitions, null, $inMemoryMetadataStore);
        ```

4.1.0
-----

 * Deprecated the `DefinitionBuilder::reset()` method, use the `clear()` one instead.
 * Deprecated the usage of `add(Workflow $workflow, $supportStrategy)` in `Workflow/Registry`, use `addWorkflow(WorkflowInterface, $supportStrategy)` instead.
 * Deprecated the usage of `SupportStrategyInterface`, use `WorkflowSupportStrategyInterface` instead.
 * The `Workflow` class now implements `WorkflowInterface`.
 * Deprecated the class `ClassInstanceSupportStrategy` in favor of the class `InstanceOfSupportStrategy`.
 * Added TransitionBlockers as a way to pass around reasons why exactly
   transitions can't be made.
 * Added a `MetadataStore`.
 * Added `Registry::all` to return all the workflows associated with the
   specific subject.

4.0.0
-----

 * Removed class name support in `WorkflowRegistry::add()` as second parameter.

3.4.0
-----

 * Added guard `is_valid()` method support.
 * Added support for `Event::getWorkflowName()` for "announce" events.
 * Added `workflow.completed` events which are fired after a transition is completed.

3.3.0
-----

 * Added support for expressions to guard transitions and added an `is_granted()`
   function that can be used in these expressions to use the authorization checker.
 * The `DefinitionBuilder` class now provides a fluent interface.
 * The `AuditTrailListener` now includes the workflow name in its log entries.
 * Added `workflow.entered` events which is fired after the marking has been set.
 * Deprecated class name support in `WorkflowRegistry::add()` as second parameter.
   Wrap the class name in an instance of ClassInstanceSupportStrategy instead.
 * Added support for `Event::getWorkflowName()`.
 * Added `SupportStrategyInterface` to allow custom strategies to decide whether
   or not a workflow supports a subject.
 * Added `ValidateWorkflowPass`.
