.. versionadded:: 3.3
The fluent interface for the ``DefinitionBuilder`` class was introduced in
Symfony 3.3. Before you had to call the ``addPlaces()``, ``addTransition()``
and ``build()`` methods separately.

The ``Workflow`` can now help you to decide what actions are allowed
on a blog post depending on what *place* it is in. This will keep your domain
logic in one place and not spread all over your application.
