# Changelog
## 2025-12-04 - 6.7.0 - feat(web_serviceworker)
Add per-resource metrics and request deduplication to service worker cache manager
- Introduce per-resource tracking in metrics: ICachedResource, IDomainStats, IContentTypeStats and a resourceStats map.
- Add MetricsCollector.recordResourceAccess(...) to record hits/misses, content-type and size; provide getters: getCachedResources, getDomainStats, getContentTypeStats and getResourceCount.
- Reset resourceStats when metrics are reset and limit resource entries via cleanupResourceStats to avoid memory bloat.
- Add request deduplication in CacheManager (fetchWithDeduplication) to coalesce identical concurrent fetches and a periodic safety cleanup for in-flight requests.
- Record resource accesses on cache hit and when storing new cache entries (captures content-type and body size).
- Expose a dashboard resources endpoint (/sw-dash/resources) served by the SW dashboard to return detailed resource data for SPA views.
## 2025-12-04 - 6.6.0 - feat(web_serviceworker)
Enable service worker dashboard speedtests via TypedSocket, expose ServiceWorker instance to dashboard, and add server-side speedtest handler
