February 2025 highlights for Saghen/nixpkgs focused on governance and ownership hygiene. Implemented a maintainer ownership update to move the maintainer alias from 'soispha' to 'bpeetz' across package definitions, strengthening accountability and responsibility tracking without impacting build logic. This aligns contributor records with actual ownership and reduces ambiguity in maintenance duties.
