Bug Fixes

Dashboards

• Charts no longer leak memory due to canvas elements persisting across component re-mounts.
• Legend color picker now responds correctly under rapid interactions, and chart tooltips no longer leak memory on re-render.
• Dynamic variables that depend on textbox variables now load correctly even when the textbox value is empty.

Metrics Explorer

• Multiple queries using the same metric with no unit set are now correctly rendered as separate charts instead of being forced into one.
• Metric selection in the query builder now properly responds to blur and keyboard shortcuts (Cmd+Enter), fixing cases where aggregation options would not update after selecting a metric.
• Cmd+Enter now works in the summary tab, and key values can be expanded in full instead of loading five at a time.
• The most recently seen unit is now used instead of an arbitrary one, fixing incorrect unit labels on histogram count metrics.
• Errors are now surfaced to the user instead of failing silently.

Other

• Spatial aggregation queries are now validated before execution, preventing silently incorrect results from invalid configurations.

Maintenance

• SigNoz's frontend build system has been migrated from Webpack to Vite, reducing build times from 83 seconds to 10 seconds.
• Frontend bundle size has been further reduced by lazy-loading the syntax highlighter, moving antd-table-saveas-excel out of the main bundle, switching the Service Map to a lighter dependency, and caching the Intl number formatter.
