6.2

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

    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);
