The change affects code sending VectorStoreExpirationAfter objects across 4 OpenAI operations, and existing requests continue to work. The update is a relaxation of the schema rather than a breaking change, according to the specification-based report.", "body_md": "## What changed\n\nA relaxation, not a break.
