patch
This patch release for the OpenAI Python client library, version 3.19.1, addresses two key issues affecting developer interactions with the API. It resolves a bug where single-pass tool iterables in the chat completion functionality were not being preserved correctly. Additionally, the update ensures that HTTP headers are now merged case-insensitively within the client, improving robustness. These fixes enhance the reliability of agentic workflows and client-server communication for developers using the library.
