 ## Deprecations
 
+1. Not injecting a `Sylius\Bundle\ApiBundle\ApiPlatform\Routing\IriConverter` with `ApiPlatform\Metadata\ResourceClassResolverInterface` is deprecated since Sylius 2.2 and will be required in Sylius 3.0.
+
+```php
+    public function __construct(
+        IriConverterInterface $decoratedIriConverter,
+        PathPrefixProviderInterface $pathPrefixProvider,
+        OperationResolverInterface $operationResolver,
+        RouterInterface $router,
++       ?ResourceClassResolverInterface $resourceClassResolver = null,
+    )
+```

 1. Not injecting a `tagged_iterator` with the tag `sylius_shop.modifier.address_form_values` into the constructor of `Sylius\Bundle\ShopBundle\Twig\Component\Checkout\Address\FormComponent` is deprecated since Sylius 2.2 and will be required in Sylius 3.0.
 
    This change enables extending the checkout address form with custom fields or logic by registering services tagged with `sylius_shop.modifier.address_form_values`, which implement the `AddressFormValuesModifierInterface`.
