Pydantic clears lazy import xfails, enables frame pointers

By RepoJournal · Filed · About FastAPI & Pydantic · Composed from the cited sources · methodology

Pydantic pushed two build and test hygiene changes that matter more than the day's FastAPI housekeeping, while FastAPI's news is limited to release notes and a sponsor removal.

Remove xfail on lazy imports tests (#13930) pydantic/pydantic

by Ayush Singh

The xfail markers on the lazy imports tests are gone, so a passing lazy-import path is now a requirement rather than a known gap: a regression there fails CI instead of being tolerated.

Explicitly enable frame pointers (#13896) pydantic/pydantic

by Victorien

Pydantic now explicitly enables frame pointers in its builds, which keeps stack unwinding reliable for profilers and sampling tools tracing pydantic-heavy code.

📝 Update release notes fastapi/fastapi

by latest-changes[bot]

FastAPI's release notes were regenerated alongside the sponsor update, with the commit marked to skip CI.

🔧 Update sponsors: remove Render (#16457) fastapi/fastapi

by Sebastián Ramírez

FastAPI dropped Render from its sponsors list, the only FastAPI change of the day that touches the repo outside of release notes.
