Pydantic survives ZoneInfo OS errors, FastAPI’s bothousekeeping continues

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

Pydantic’s only substantive change in the last 24 hours hardens timezone validation against OS-level failures, while the FastAPI and SQLModel desks are occupied entirely by automation and dependency maintenance.

Handle OS errors during `ZoneInfo` validation pydantic/pydantic

by Viicos

This fixes pydantic/pydantic#13908 by handling OS errors raised while validating `ZoneInfo` values, so malformed or unavailable timezone data no longer escapes as an unhandled error. If your models accept timezone strings or `ZoneInfo` fields and your process can hit OS-level lookup failures, this is the change to track.
