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.

4. Validate your changes before committing.\
