Symfony 7.1.0 released (Symfony Blog)
(symfony.com)
I particularly like the new Mapped Route Parameters.
❌ /show/{id}/
✔ /show/{id:document}/
For multiple entities, it's cleaner and more beginner-friendly than using the #[MapEntity] attribute (which is still an option).
And imo it's a good move to deprecate "not passing the mapping" even for single entities. With the mapping the behaviour is more intuitive and "feels" less magic.
