Changelog

December 11, 2025

4.45.5

(fix): Fix file upload conditional check using wire_value instead of snake_case parameter name, which caused mypy “name not defined” errors when the API field name differed from the Python parameter name (e.g., MyFile vs my_file).

4.45.4

(fix): Fix offset pagination to handle None items when calculating next page offset.
