+## [1.7.1] - 2026-05-20
+
+Maintenance release. Dependency and lock-file updates only — there are no
+source code or public API changes. The published runtime dependencies
+(`httpx`, `typing_extensions`) are unchanged; the updates below affect the
+pinned development, testing, and optional-extra dependencies in `uv.lock`
+and are not shipped in the wheel/sdist.
+
+### Security
+
+- Updated pinned development and transitive dependencies in `uv.lock` to
+  resolve reported advisories. None of these affect the published runtime
+  dependencies:
+  - `idna` 3.11 → 3.15 — fixes a bypass of the CVE-2024-3651 mitigation in
+    `idna.encode()` (transitive via `httpx`/`anyio`).
+  - `pytest` 9.0.2 → 9.0.3 — fixes vulnerable tmpdir handling (dev only).
+  - `python-dotenv` 1.2.1 → 1.2.2 — fixes symlink following in `set_key`
+    that allowed arbitrary file overwrite (dev only).
+  - `pygments` 2.19.2 → 2.20.0 — fixes a ReDoS in GUID matching
+    (transitive, dev only).
+
+### Changed
+
+- Bumped `aiohttp` and added `aiohappyeyeballs` in `uv.lock` (#17).
+- Locked the optional FHIR extras (`fhirpy`, `fhir-resources`) and their
+  transitive dependencies in `uv.lock`. These were already declared in
+  `pyproject.toml` but had never been captured in the lock file.
