## Versioning and releases
215216

216-
- The library version is tracked in `pyproject.toml` (`project.version`). Use SemVer.
217-
- Workflow:
218-
- Contributors: branch off `main` (or `dev` if used) and open PRs.
219-
- Maintainer (release): bump version, tag, and publish to PyPI.
220-
- Tag on `main`: `git tag -a vX.Y.Z -m "Release vX.Y.Z" && git push --tags`.
217+
- The version is tracked in `pyproject.toml` (`project.version`) and mirrored in `src/pythonnative/__init__.py` as `__version__`. Both files are updated automatically by [python-semantic-release](https://python-semantic-release.readthedocs.io/).
218+
- **Automated release pipeline** (on every merge to `main`):
219+
1. `python-semantic-release` scans Conventional Commit messages since the last tag.
220+
2. It determines the next SemVer bump: `feat` → **minor**, `fix`/`perf` → **patch**, `BREAKING CHANGE` → **major** (minor while version < 1.0).
221+
3. Version files are updated, `CHANGELOG.md` is generated, and a tagged release commit (`chore(release): vX.Y.Z`) is pushed.
222+
4. A GitHub Release is created with auto-generated release notes and the built sdist/wheel attached.
223+
5. When drafts are disabled, the package is also published to PyPI via Trusted Publishing.
224+
- **Draft / published toggle**: the `DRAFT_RELEASE` variable at the top of `.github/workflows/release.yml` controls release mode. Set to `"true"` (the default) for draft GitHub Releases with PyPI publishing skipped; flip to `"false"` to publish releases and upload to PyPI immediately.
225+
- Commit types that trigger a release: `feat` (minor), `fix` and `perf` (patch), `BREAKING CHANGE` (major). All other types (`build`, `chore`, `ci`, `docs`, `refactor`, `revert`, `style`, `test`) are recorded in the changelog but do **not** trigger a release on their own.
226+
- Tag format: `v`-prefixed (e.g., `v0.4.0`).
227+
- Manual version bumps are no longer needed — just merge PRs with valid Conventional Commit titles. For ad-hoc runs, use the workflow's **Run workflow** button (`workflow_dispatch`).

### CI
260+
261+
- **CI** (`ci.yml`): runs formatter, linter, type checker, and tests on every push and PR.
262+
- **PR Lint** (`pr-lint.yml`): validates the PR title against Conventional Commits format (protects squash merges) and checks individual commit messages via commitlint (protects rebase merges). Recommended: add the **PR title** job as a required status check in branch-protection settings.
263+
- **Release** (`release.yml`): runs on merge to `main`; computes version, generates changelog, tags, creates GitHub Release, and (when `DRAFT_RELEASE` is `"false"`) publishes to PyPI.
264+
- **Docs** (`docs.yml`): deploys documentation to GitHub Pages on push to `main`.
