+| Bug fix?      | yes/no
+| New feature?  | yes/no <!-- please update src/**/CHANGELOG.md files -->
+| Docs?         | yes/no <!-- required for new features -->
+| Issues        | Fix #... <!-- prefix each issue number with "Fix #", no need to create an issue if none exist, explain below instead -->
+| License       | MIT
+
+<!--
+Replace this notice by a description of your feature/bugfix.
+This will help reviewers and should be a good start for the documentation.
+
+Additionally (see https://symfony.com/releases):
+ - Always add tests and ensure they pass.
+ - For new features, provide some code snippets to help understand usage.
+ - Features and deprecations must be submitted against branch main.
+ - Update/add documentation as required (we can help!)
+ - Changelog entry should follow https://symfony.com/doc/current/contributing/code/conventions.html#writing-a-changelog-entry
+ - Never break backward compatibility (see https://symfony.com/bc).
