- Delivers a complete, valuable change (feature, bug fix, or improvement).
- Has a concise title (e.g., `[S3] Fix bucket policy parsing #1234`) and a summary with context, referencing issues (e.g., `#1234`).
- Contains well-written, logical commits explaining *why* changes were made (e.g., “Add S3 bucket tagging support so that users can organize resources efficiently”).

+ Create a topic branch from where you want to base your work (this is usually the master branch).
  Push your changes to a topic branch in your fork of the repository.
+ Make commits of logical units.
+ Respect the original code style: by using the same [codestyle][code-style],
  patches should only highlight the actual difference, not being disturbed by any formatting issues:
  + Only use spaces for indentation.
