Release new version on Packagist?

I see Symfony 6 compatibility is already present on master, but those changes are not yet released. The latest version on Packagist is v1.1.4.

It would be nice if you could release a new version that includes these changes 🙌

array_unique throws 'Error: Nesting level too deep - recursive dependency?' exception

array_uniqe doesn't use strict comparison, which should always be used when comparing objects.

line 77: ->setParameter('subjects', array_unique($subjects, \SORT_REGULAR))

Handle null relations ?

Hello,

I am not sure it is an issue, but I'd like to discuss it with you.
In my application I have an OrderItem with a ManyToOne Relation with another Entity called Child.
An OrderItem can have 0 or 1 child defined.

Now, in my orderRepository, I want to get OrderItems with child and its parent data, so I tried this way :

$this->associationHydrator->hydrateAssociations($order, [
            'items',
            'items.concernedChild.parent',
]);

But as concernedChild may be null I get an exception for this line of AssociationHydrator :
$subjects = array_map([$this->entityManager->getUnitOfWork(), 'getEntityIdentifier'], $subjects);

I managed to get it work by adding a simple filter on the $subjects array like this :

$subjects = array_filter($subjects, function ($subject) {
       return $subject !== null;
});

What do you think ? is it normal that I get an Exception ? and is my solution valuable ?

Thanks !
