During November 2024, this developer modernized runtime support in the hiddenSymmetries/simsopt repository by retiring Python 3.8 across all CI workflows, Singularity containers, and dependency constraints. Using Python and YAML, they updated build systems and CI/CD pipelines to enforce a new minimum Python version, streamlining the build and test processes. This change reduced maintenance overhead and accelerated feedback cycles, allowing the team to focus on adopting newer Python features. The developer also ensured that documentation and release notes accurately reflected the updated support policy. Their work demonstrated a focused approach to technical debt and process improvement within Python packaging.
