During February 2025, Maralorn updated the Nix Output Monitor package in the Saghen/nixpkgs repository, focusing on package management using the Nix language. The work involved bumping the package version to 2.1.5, updating the download URL, and recalculating the SHA256 checksum to ensure build integrity and reproducibility. By aligning the package metadata with upstream releases, Maralorn reduced maintenance overhead and improved security through accurate checksum validation. The update was delivered as a single, traceable commit, facilitating downstream CI and quality control. This contribution demonstrated a methodical approach to package maintenance, emphasizing reliability and adherence to Nixpkgs packaging standards.
