* Deprecate calling `Definition::setInitialPlaces()` without arguments

* Remove `InvalidTokenConfigurationException`

* Add support for getting updated context after a transition

* Deprecate `InvalidTokenConfigurationException`

* Added `MermaidDumper` to dump Workflow graphs in the Mermaid.js flowchart format

* 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()`

* 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

* Added argument `$context` to `MarkingStoreInterface::setMarking()`

* Marked all dispatched event classes as `@final`

* 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.

* The `TransitionEvent` is able to modify the context.

* 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 `LeaveEvent` on `workflow.leave`

* Dispatch `TransitionEvent` on `workflow.transition`

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

* 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.

* The `AuditTrailListener` now includes the workflow name in its log entries.

* Added `workflow.entered` events which is fired after the marking has been set.
