A dependency bump and a schema fix landed across two repos: FastAPI moved pillow to 13.0.0 and dnspython to 2.9.2, while Pydantic corrected the JSON Schema emitted for the arguments schema.

Fix JSON Schema for `arguments` schema pydantic/pydantic

by Viicos

Pydantic's PR fixes the JSON Schema output for the arguments schema, closing the issue the change is scoped to. If you generate OpenAPI or client code from Pydantic models that carry an arguments field, this is the behavior to re-check.

⬆️ Bump pillow to 13.0.0 and dnspython to 2.9.2 fastapi/fastapi

by YuriiMotov

FastAPI's Pillow goes from the prior pin to 13.0.0 and dnspython to 2.9.2. Anyone pinning overlapping versions in their own lockfile should expect those two packages to resolve at these releases.

⬆️ Bump pillow to 13.0.0 and dnspython to 2.9.2 (#16685) fastapi/fastapi

by Yurii Motov

The same bump merged to the FastAPI tree, so the new pillow and dnspython versions are now what a fresh install of the branch picks up.
