In January 2025, delivered a critical build stability improvement for GaetanLepage/nixpkgs by implementing the Django-q2 Build Dependency Tagging Fix: Use Git tag for source. This change switches the source reference to a Git tag instead of a generic ref, resolving the hiredis override issue and ensuring the build uses the correct django-q2 version tag. The fix enhances reproducibility across CI environments and reduces build failures due to incorrect source references. It also strengthens dependency management for python313Packages.django-q2 and provides a clear audit trail for future changes.
