Worked on the polyapi-python repository to address a subtle but critical issue in API integration by restoring explicit None argument handling in the client. Using Python, the developer reverted previous logic that stripped None values from function arguments, ensuring that the distinction between omitted and explicitly None parameters was preserved during API calls. This change improved the reliability of API interactions by preventing misinterpretation of input values, which could otherwise lead to subtle defects. The update included a development version bump to support ongoing iteration and maintain clear versioning. The work demonstrated careful attention to detail in Python development and API integration.
