This project now uses python-semantic-release.

1. Merge conventional commits into master
2. Let the Semantic Release GitHub Actions workflow determine the next version
3. The workflow updates datemath/_version.py, updates CHANGELOG.md, creates the tag, and publishes a GitHub release
4. The PyPI publish workflow runs from that GitHub release

• feat: bumps the minor version
• fix: bumps the patch version
• perf: bumps the patch version
• BREAKING CHANGE: in the body or footer bumps the major version

Commits like docs:, test:, ci:, and chore: are allowed but do not trigger a release by themselves.
