 # Changelog
 
+## 2025-12-04 - 7.1.0 - feat(swdash)
+Add live speedtest progress UI to service worker dashboard
+
+- Introduce reactive speedtest state (phase, progress, elapsed) in sw-dash-overview component
+- Start a progress interval to animate overall test progress and estimate phases (latency, download, upload)
+- Dispatch 'speedtest-complete' event and show a brief complete state before resetting UI
+- Add helper methods for phase labels and elapsed time formatting
+- Add CSS for progress bar, shimmer animation and phase pulse to sw-dash-styles
+
 ## 2025-12-04 - 7.0.0 - BREAKING CHANGE(serviceworker)
 Move serviceworker speedtest to time-based chunked transfers and update dashboard/server contract
