In December 2024, Hendrik Fütterer updated the rdmorganiser/rdmo repository to require Python 3.9 as the minimum supported version, removing Python 3.8 support throughout the project. He aligned the continuous integration pipelines, contribution guidelines, and project metadata to reflect this change, ensuring consistency across development and deployment workflows. Using skills in CI/CD, project configuration, and Python development, Hendrik worked with YAML and TOML to update configuration files and documentation. This focused update reduced maintenance overhead and clarified runtime requirements for contributors and users. The work demonstrated a methodical approach to dependency management and project modernization within a collaborative environment.
