This includes adding the description of the changes to the `accepted-public-api-changes.json` file, and providing a reason for each change.
You can add the changes to any place in the file, e.g. at the top.

3. Make sure the file with accepted changes is sorted.\
Use the `./gradlew :architecture-test:sortAcceptedApiChanges` task to sort the file.

* Traiter des données :
    * Par exemple, si vous recevez un fichier qui doit passer par un traitement lent, vous pouvez retourner une réponse «Accepted» (HTTP 202) puis faire le traitement en arrière-plan.


## Utiliser `BackgroundTasks`

* Processing data:
    * For example, let's say you receive a file that must go through a slow process, you can return a response of "Accepted" (HTTP 202) and process the file in the background.

## Using `BackgroundTasks`

First, import `BackgroundTasks` and define a parameter in your *path operation function* with a type declaration of `BackgroundTasks`:

                context.terminal
                        .writer()
                        .println(messageBuilderFactory
                                .builder()
                                .warning("Values not accepted; not saving configuration.")
                                .build());
                return BAD_OPERATION;
            }
        }

        return OK;
    }

   *
   * <p>Unlike {@link Double#parseDouble(String)}, this method returns {@code null} instead of
   * throwing an exception if parsing fails. Valid inputs are exactly those accepted by {@link
   * Double#valueOf(String)}, except that leading and trailing whitespace is not permitted.
   *
   * <p>This implementation is likely to be faster than {@code Double.parseDouble} if many failures
