This are the controller changes to give the component MVC classes more meaningful names. Controllers will have now Controller as suffix to their class name. So Joomla\Component\Banners\Administrator\Controller\Banners becomes Joomla\Component\Banners\Administrator\Controller\BannersController.
Additionally the default controller which is called just Controller gets the name DisplayController, to better reflect whet the class does.
