In March 2025, Michael Jaehn rebranded and reorganized the flexpart-cosmo package to flexpart-cosmo-icon within the C2SM/spack-c2sm repository, focusing on improving packaging consistency and maintainability. He updated the class name, homepage, and repository URL to align with the new organizational structure, and adapted the test suite to reflect these changes. Using Python and leveraging skills in code refactoring and package management, Michael ensured a smooth migration for downstream users and CI workflows. The work addressed discoverability and long-term support, demonstrating careful attention to repository organization and the technical details required for seamless package transitions.
