UPGRADE-2.4.md

UPGRADE FROM 2.3 to 2.4

Form

• The constructor parameter $precision in IntegerToLocalizedStringTransformer is now ignored completely, because a precision does not make sense for integers.

EventDispatcher

• The getDispatcher() and getName() methods from Symfony\Component\EventDispatcher\Event are deprecated, the event dispatcher instance and event name can be received in the listener call instead.

  Before:

  use Symfony\Component\EventDispatcher\Event;
  
  class Foo
  {
      public function myFooListener(Event $event)
      {
          $dispatcher = $event->getDispatcher();
          $eventName = $event->getName();
          $dispatcher->dispatch('log', $event);
  
          // ... more code
     }
  }

  After:

  use Symfony\Component\EventDispatcher\Event;
  use Symfony\Component\EventDispatcher\EventDispatcherInterface;
  
  class Foo
  {
      public function myFooListener(Event $event, $eventName, EventDispatcherInterface $dispatcher)
      {
          $dispatcher->dispatch('log', $event);
  
          // ... more code
      }
  }
