Egor Rodygin upgraded the MapGL library to version 1.67.0 in the 2gis/on-premise-helm-charts repository, focusing on improving feature parity and maintainability for on-premise deployments. He updated the Helm chart’s Chart.yaml, synchronized documentation in README.md, and aligned configuration defaults in values.yaml to match the new library requirements. Working primarily with YAML and leveraging DevOps and Kubernetes expertise, Egor ensured that the upgrade process was clean and that all user-facing guidance reflected the latest changes. The work addressed compatibility and default behavior across environments, demonstrating careful attention to detail in both code and documentation over the course of the month.
