Attributes have been around for a while now. We should deprecate annotations as the minimum requirement is now PHP >= 8.

[Vincz]

We should also update the folder and the namespace and deprecate the old one.
@mcg-web I have never done something like that. Is there a way to deprecate the old namespace and folder (but let it work) while having the new one without duplicating the files in it?

[Vincz]

One way to to it would be to subclass new namespace with the old one.
For example:

<?php

namespace Overblog\GraphQLBundle\Annotation;

use Overblog\GraphQLBundle\Annotation\Type as BaseType;

class Type extends BaseType
{
}

Not sure if it would work.

[Vincz]

Another way would be with composer autoload.
Would something like this could work in the composer.json ?

    "autoload": {
        "psr-4": {
            "Overblog\\GraphQLBundle\\Annotation\\": "Attribute"
          }
    }
