+## 2026-01-28 - 1.8.0 - feat(streaming)
+add global activity watchers, client-side buffering, and improved real-time streaming UX
+
+- Introduce global MongoDB and S3 watchers in ChangeStreamManager to feed a deployment-level activity stream (start/stop automatically based on subscribers)
+- ChangeStreamManager: activity buffering, globalWatchersActive flag, start/stop global watchers, and emitMongoActivityEvent API for handlers
+- Mongo API handlers accept an optional ChangeStreamManager and emit activity events for DB/collection/document operations
+- Server now initializes ChangeStreamManager earlier and passes it to registerMongoHandlers; request context uses localData.peer.id for WebSocket peer lookup
+- Client: ChangeStreamService adds connection promise/ensureConnected, activity buffering across tabs, and more robust connect/subscribe flows (waits for connect in-flight)
+- UI updates: activity stream shows relative times with live clock, buffers events from app-level subscription, auto-scroll behavior adjusted, and connection-based re-subscription
+- Mongo/S3 browser components ensure RxJS listeners are attached before server-side subscribe and surface connection status
+- S3 browser: add drag-and-drop folder upload support (webkitdirectory), recursive folder entry traversal, upload with preserved relative paths, and column refresh/refreshAll logic
+- Minor API/behavioral changes use connection peer id via conn.peer?.id when resolving target connections
