 # Changelog

+## 2025-12-04 - 7.5.0 - feat(serviceworker)
+Add real-time service worker push updates and DeesComms integration (metrics, events, resource caching)
+
+- Integrate DeesComms push channel for real-time SW → client communication and export/consume deesComms in relevant plugin modules.
+- Add typed push message interfaces for events, metrics snapshots and resource-cached notifications in serviceworker interfaces.
+- Implement backend push methods: pushEvent, pushMetricsUpdate (with 500ms throttle) and pushResourceCached in ServiceworkerBackend.
+- Trigger push updates from MetricsCollector and PersistentStore so metrics and logged events are broadcast to connected clients.
+- Add client-side DeesComms handlers in sw-dash app: receive metrics, event logs and resource notifications; add heartbeat and initial HTTP seed to maintain SW health state.
+- Add event push listener and cleanup in sw-dash-events component to prepend incoming events and avoid leaks.
+- Expose getServiceWorkerBackend() from SW init for internal modules to call push methods.
+- Misc: implement request deduplication and various robustness improvements (throttling, heartbeat, safer polling, removed noisy debug logs).
+
+## 2025-12-04 - 7.4.1 - fix(web_serviceworker)
+Improve service worker persistence, metrics and caching robustness
+
+- Ensure persistent store is initialized before use in dashboard handlers and service worker activation/handlers (calls to persistentStore.init())
+- Make serveCumulativeMetrics async and align fetchEvent.respondWith usage (remove unnecessary Promise.resolve)
+- Change persistent WebStore database name to 'losslessServiceworkerPersistent' to separate durable store from runtime store
+- Make PersistentStore.init() more resilient: add detailed logging, avoid throwing on init failure, mark initialized to prevent retry loops, and start periodic save only after load
+- Ensure logEvent awaits initialization and adds defensive logging around reading/writing the event log
+- Add request deduplication logic and improved cache handling in CacheManager (fetchWithDeduplication usage and safer respondWith)
+
+## 2025-12-04 - 7.4.0 - feat(serviceworker)
+Add persistent event store, cumulative metrics and dashboard events UI for service worker observability
+
+- Add PersistentStore (ts_web_serviceworker/classes.persistentstore.ts) to persist event log and cumulative metrics with retention policy and periodic saving.
+- Introduce persistent event types and interfaces for event log and cumulative metrics (ts_interfaces/serviceworker.ts).
+- Log lifecycle, update, network and speedtest events to the persistent store (install, activate, update available/applied/error, network online/offline, speedtest started/completed/failed, cache invalidation).
+- Expose persistent-store APIs via typed handlers in the service worker backend: serviceworker_getEventLog, serviceworker_getCumulativeMetrics, serviceworker_clearEventLog, serviceworker_getEventCount.
+- Serve new dashboard endpoints from the service worker: /sw-dash/events (GET), /sw-dash/events/count (GET), /sw-dash/cumulative-metrics (GET) and DELETE /sw-dash/events to clear the log (handled in classes.cachemanager and classes.dashboard).
+- Add sw-dash events panel component (ts_swdash/sw-dash-events.ts) and integrate an Events tab into the dashboard UI (ts_swdash/sw-dash-app.ts, sw-dash-overview.ts shows 1h event count).
+- Reset cumulative metrics on cache invalidation and increment swRestartCount on PersistentStore.init().
+- Record speedtest lifecycle events (started/completed/failed) and include details in the event log.
+
+## 2025-12-04 - 7.3.0 - feat(serviceworker)
+Modernize SW dashboard UI and improve service worker backend and server tooling
+
+- Revamped sw-dash UI: new header/logo, uptime badge, live auto-refresh indicator, reorganized panels and improved speedtest UI and controls
+- Shared styles overhaul: new theming variables, spacing scale, badges, refined progress/pulse animations and cleaner typography
+- Dashboard internals: metrics endpoint and SPA shell updated; Lit bundle loading and table sort icon changed to ↑/↓
+- Service worker: added request deduplication (in-flight request coalescing), safer caching logic, consistent CORS/caching headers, and cache revalidation
+- Metrics: richer MetricsCollector with per-resource tracking, domain/content-type stats, speedtest metrics and better summary/stat helpers
+- Update & network managers: rate-limited update checks, debounced update/revalidation tasks, online/offline checks and improved retry/backoff logic
+- TypedServer & tooling: addRoute API for custom routes, improved HTML reload script injection, TypedSocket integration and a backend speedtest handler
+- servertools: improved static/proxy handlers (more robust path extraction, compression handling) and deprecation notice for addTypedSocket()
+
 ## 2025-12-04 - 7.2.0 - feat(serviceworker)
 Add service worker status updates, EventBus and UI status pill for realtime observability
