Mar 1, 2025March 2025: Delivered topology thresholds integration with per-location data and reactive nodeId updates, enabling real-time, location-specific threshold insights. Refined thresholds UI into a card-based, searchable interface with tree-menu summaries and per-location indicators. Expanded threshold and crossing panels with additional details and focus on relevant warnings, including open/close controls for the threshold panel. Strengthened reliability and performance through naming consistency, DOM cleanup, and virtual scrolling for long lists, plus improvements to timeseries loading indicators and reduction of unnecessary data fetches during edits. These changes deliver faster, more accurate insights and smoother workflows for analysts and decision-makers.

Jan 1, 2025January 2025: Delivered performance and quality enhancements for Deltares/fews-web-oc TimeSeriesChart. Implemented rendering optimizations to redraw only the time indicator, eliminated chart-level loading indicators to remove flicker, and stabilized the initial load for a reliable first render. Also implemented lint and readability improvements, and improved dummy URL construction for series requests to boost maintainability and robustness. These changes reduce render workload, improve UX stability, and contribute to a cleaner, more maintainable codebase for future time-series features.
