Arne updated the configuration management for the Ensembl/public-plugins repository by delivering a targeted INI file change that references the latest 'age of base' dataset for Homo sapiens genome calculations. Focusing on INI syntax and configuration management principles, Arne ensured the new dataset was correctly integrated by updating file and name attributes within homo_sapiens.ini. The change was validated for backward compatibility across environments, minimizing risk of regression in dataset selection. Arne documented the update for future maintenance, demonstrating attention to process and traceability. The work addressed a specific data update need, reflecting a focused and methodical approach to configuration management.
