-body: |
-    Rewrite exports to run them asynchronously
-
-changelog: |
-    - Add new methods to serialize data using the rector rule
-    - Remove all references to the Request in filters, aggregators, filters. Actually, the most frequent occurence is `$security->getUser()`.
-    - Refactor manually the initializeQuery method
-    - Remove the injection of ExportManager into the constructor of each export element:
-
-      ```diff
-
-      - class MyFormatter implements FormatterInterface
-      + class MyFormatter implements FormatterInterface, \Chill\MainBundle\Export\ExportManagerAwareInterface
-      {
-      +    use \Chill\MainBundle\Export\Helper\ExportManagerAwareTrait;
-
-      -    public function __construct(private ExportManager $exportmanager) {}
-
-           public function MyMethod(): void
-           {
-      -          $this->exportManager->getFilter('alias');
-      +          $this->getExportManager()->getFilter('alias');
-           }
-      }
-      ```
-    - configure messenger to handle export in a queue:
-
-    ```diff
-    # config/packages/messenger.yaml
-    framework:
-        messenger:
-            routing:
-    +            'Chill\MainBundle\Export\Messenger\ExportRequestGenerationMessage': priority
-    ```
-
-    - add missing methods to exports, aggregators, filters, formatter:
-
-      ```php
-      public function normalizeFormData(array $formData): array;
-
-      public function denormalizeFormData(array $formData, int $fromVersion): array;
-      ```
-
-      There are rector rules to generate those methods:
-
-      - `Chill\Utils\Rector\Rector\ChillBundleAddNormalizationMethodsOnExportRector`
-
-      See:
-
-      ```php
-      // upgrade chill exports
-      $rectorConfig->rules([\Chill\Utils\Rector\Rector\ChillBundleAddNormalizationMethodsOnExportRector::class]);
-      ```
-
-      This rule will create most of the work necessary, but some manuals changes are still necessary:
-
-      - we must set manually the correct repository for method `denormalizeDoctrineEntity`;
-      - when the form data contains some entities, and the form type is not one of EntityType::class, PickUserDynamicType::class, PickUserLocationType::class, PickThirdpartyDynamicType::class, Select2CountryType::class, then we must handle the normalization manually (using the `\Chill\MainBundle\Export\ExportDataNormalizerTrait`)
