Dec 1, 2025December 2025: Packaging stabilization for cda-tum/mqt-qecc. Implemented a sdist packaging fix by updating pyproject.toml to ensure the version file is tracked, eliminating errors due to untracked version metadata. This reduces release risk and CI churn. Also added tests for packaging behavior and updated user-facing documentation, changelog, and upgrade guidance. No new features released this month; the work strengthens the foundation for reliable releases and future feature work. Technologies demonstrated include Python packaging (pyproject.toml), Git/versioning, test automation, and documentation practices.
