Jul 1, 2025July 2025: Focused on improving developer productivity and CI reliability for igmhub/picca by updating the pylint configuration to disable the ungrouped-imports check. This change reduces lint noise while preserving overall code quality, enabling faster iteration on imports and module structure. Impact includes smoother PR reviews, fewer CI reruns due to import-related warnings, and a clearer path for refactoring where imports are organized by logical grouping rather than strictly grouped per pylint.
