FastAPI stripped unnecessary unsafe checkout flags from workflows while dependency updates sweep both repos, but Pydantic's PyO3 upgrade remains blocked on jiter.

FastAPI's security posture just got sharper. The team removed `allow-unsafe-pr-checkout: true` directives that turned out to be unnecessary overhead [2] [4], a small but disciplined move that reflects maturation in their CI/CD thinking. That followed a broader github-actions refresh [3] bumping checkout to v7, setup-python to 6.3.0, and actions/cache to 6.1.0. On the dependency front, FastAPI landed 10 python-packages updates [1] including pytest 9.0.3 to 9.1.1, httpx2 2.3.0 to 2.4.0, and ruff 0.15.16 to 0.15.18, all routine maintenance that keeps the test suite sharp. Over in Pydantic land, the team is staging a PyO3 0.29 upgrade [6] but it's waiting on jiter/254 to ship first, so that one's not moving until upstream clears. Meanwhile, Pydantic's rust-deps group picked up six updates across pydantic-core [5], including regex 1.12.4, lru 0.18.0, and serde_json 1.0.150. These are the kinds of incremental wins that keep core performance tight.
