 Releases are automated when a pull request is merged to `main`. CI reads the **merged PR title** to decide whether and how to bump the version.

 ### How it works

 1. Open a PR targeting `main` (see [`.gitea/PULL_REQUEST_TEMPLATE.md`](.gitea/PULL_REQUEST_TEMPLATE.md)).
 2. If the PR changes files under `python_repositories/`, the title **must** start with a version bump prefix (enforced by CI).
-3. On merge, [`release.yml`](.gitea/workflows/release.yml) bumps [`pyproject.toml`](pyproject.toml) and syncs [`uv.lock`](uv.lock), commits, tags `vX.Y.Z`, creates a Gitea release with auto-generated notes, pushes the tag, and publishes the package to the Gitea Package Registry.
+3. On merge, [`release.yml`](.gitea/workflows/release.yml) bumps [`pyproject.toml`](pyproject.toml) and syncs [`uv.lock`](uv.lock), updates [`CHANGELOG.md`](CHANGELOG.md), commits, tags `vX.Y.Z`, creates a Gitea release with auto-generated notes, pushes the tag, and publishes the package to the Gitea Package Registry.
 4. [`publish.yml`](.gitea/workflows/publish.yml) handles manual `v*.*.*` tag pushes only (automated releases publish from `release.yml` because release commits use `[skip ci]`, which suppresses tag-push workflows).

 Docs-, CI-, and test-only PRs do not need a prefix and will not trigger a release.
