5.2.0
-----

 * Added `Workflow::getEnabledTransition()` to easily retrieve a specific transition object
 * Added context to the event dispatched
 * Dispatch an event when the subject enters in the workflow for the very first time
 * Added a default context to the previous event
 * Added support for specifying which events should be dispatched when calling `workflow->apply()`

5.1.0
-----

 * Added context to `TransitionException` and its child classes whenever they are thrown in `Workflow::apply()`
 * Added `Registry::has()` to check if a workflow exists
 * Added support for `$context[Workflow::DISABLE_ANNOUNCE_EVENT] = true` when calling `workflow->apply()` to not fire the announce event

5.0.0
-----

-----

 * Marked all dispatched event classes as `@final`

 * Add style to transitions by declaring metadata:

    use Symfony\Component\Workflow\Definition;
    use Symfony\Component\Workflow\Metadata\InMemoryMetadataStore;

    $transitionsMetadata = new \SplObjectStorage();
    $transitionsMetadata[$transition] = [
        'color' => 'Red',
        'arrow_color' => '#00ff00',
    ];
    $inMemoryMetadataStore = new InMemoryMetadataStore([], [], $transitionsMetadata);

    return new Definition($places, $transitions, null, $inMemoryMetadataStore);
 * Dispatch `GuardEvent` on `workflow.guard`

 * Dispatch `AnnounceEvent` on `workflow.announce`
 * Added support for many `initialPlaces`
 * Deprecated `DefinitionBuilder::setInitialPlace()` method, use `DefinitionBuilder::setInitialPlaces()` instead.

 * Deprecated the `SingleStateMarkingStore` class, use the `MethodMarkingStore` instead.

4.1.0
-----
