January 2025 monthly summary for Ensembl/public-plugins focusing on installation reliability, security, and contributor experience. Delivered the VEP Installation Script Options Enhancement, adding two new flags --USE_HTTPS_PROTO and --GITHUBTOKEN to enable HTTPS data downloads and GitHub API rate limit management during installation. Updated installation documentation to reflect the new options. This work reduces network-related installation failures, improves data integrity, and lays groundwork for token-based access in future installs. No major bugs were reported this month; the changes are isolated to the installer workflow and do not affect runtime plugin functionality. Overall, the initiative enhances deployment repeatability and scalability, delivering measurable business value across the project.
