March 2025 was focused on reliability and user experience improvements for konturio/disaster-ninja-fe. Implemented a unified, dynamic zoom mechanism for multivariate and MCDA layers, centralizing min/max zoom validation across renderers to deliver more reliable map visualizations. Resolved a dependency stability issue by reverting i18next-conv to a stable version and updating the lockfile to preserve reproducible builds. These changes reduce zoom-related issues in production and improve developer confidence in ongoing maintenance and feature delivery.
