 ## [Unreleased]
+### Changed
+- ACTION SUGGESTED: If you are using GitHub Actions, it's recomended to use `!cancelled()` instead of `always()` for moodle-plugin-ci tests. Adding a final step that always returns failure when the workflow is cancelled will ensure that cancelled workflows are not marked as successful. For a working example, please reference the updated `gha.dist.yml` file.
