+# semvertag 0.8.2 — release pipeline on PyPI Trusted Publishing
+
+No library changes. The package is identical to 0.8.1; this release exercises the new publish path end-to-end.
+
+## CI
+
+- Releases now authenticate to PyPI via **Trusted Publishing (OIDC)** instead of a long-lived `PYPI_TOKEN` secret. `uv publish` auto-detects the GitHub Actions id-token; the release job runs under a `pypi` environment that scopes the trusted publisher (#46).
+
+## Downstream
+
+No action required. Nothing about the installed package changes.
