# Changelog
## 2025-12-04 - 6.2.0 - feat(web_serviceworker)
Add service-worker dashboard and request deduplication; improve caching, metrics and error handling
- Add DashboardGenerator to serve an interactive terminal-style dashboard at /sw-dash and a metrics JSON endpoint at /sw-dash/metrics
- Introduce request deduplication in CacheManager to coalesce concurrent network fetches and avoid duplicate requests
- Add periodic cleanup for in-flight request tracking to prevent unbounded memory growth
- Improve caching flow: preserve response headers (excluding cache-control headers), ensure CORS headers and Cross-Origin-Resource-Policy, and store response bodies as blobs to avoid locked stream issues
- Provide clearer 500 error HTML responses for failed fetches to aid debugging
- Integrate metrics and event emissions for network and cache operations (record request success/failure, cache hits/misses, and emit corresponding events)
## 2025-12-04 - 6.1.0 - feat(web_serviceworker)
Enhance service worker subsystem: add metrics, event bus, error handling, config and caching/update improvements; make client connection & polling robust
