January 2026 monthly summary for datalens-ui (datalens-tech/datalens-ui). Focused on stabilizing the dashboard loading workflow and improving reliability of metrics display.

November 2025: Delivered Dashboard Event Dispatch Enhancements for datalens-ui.

No major bugs reported this month; however, the new events enable better downstream telemetry and user experience.
