Challenge 2 / 2

You’re upgrading to Symfony 7.4 and you run symfony composer recipe:update. After that, your teammate says: “Wait… why did controllers outside src/Controller suddenly start working?” What’s the best explanation?

The new config/reference.php file tells Symfony where controllers live, so it can find them anywhere.

The routing recipe got simpler: now it loads any class with #[Route] attributes, not just ones inside src/Controller.

Composer update moved all controllers into src/Controller automatically during the upgrade.

Symfony 7.4 auto-registers every PHP class as a controller, even if it has no routes.
