+## 2026-01-26 - 1.6.1 - fix(ci)
+add Gitea CI workflows, documentation updates, and packaging metadata tweaks
+
+- Add .gitea workflow files for tag and non-tag pushes (security, test, release, metadata jobs)
+- Add buildDocs script (tsdoc) and add bugs/homepage/pnpm.overrides entries to package.json
+- Update README and readme.hints.md with real-time streaming docs, formatting/table fixes, and examples punctuation fixes
+- Tidy npmextra.json formatting and array inline style changes
+- Update changelog.md entries and correct trailing newline/formatting
+- Minor .gitignore whitespace fix
+
+## 2026-01-25 - 1.6.0 - feat(readme)
+
+document real-time change streaming and expand README with features, architecture, and configuration updates
+
+- Add Real-Time Change Streaming section: MongoDB change streams, S3 polling (ETag), activity stream, WebSocket subscriptions, and auto-reconnect behavior
+- Expand S3 and MongoDB feature lists: in-place text editing, enhanced previews (code), show/hide system databases, live indicators, context menus
+- Reintroduce project-level npmextra.json example and clarify environment variable names and priority order
+- Add Architecture and How It Works sections with tree layout and streaming design details
+- Minor wording, formatting, and installation clarifications (prefer pnpm examples, fix LICENSE filename case)
+
+## 2026-01-25 - 1.5.0 - feat(streaming)
+
+add real-time streaming (MongoDB change streams & S3 bucket watchers) with WebSocket subscriptions and activity stream UI
+
+- Server: add ChangeStreamManager to manage MongoDB change streams and S3 BucketWatcher subscriptions, handle subscription lifecycle, activity ring buffer and push events via TypedSocket.
+- API: introduce streaming TypedRequest interfaces and register new handlers (subscribeMongo/unsubscribeMongo, subscribeS3/unsubscribeS3, subscribeActivity/unsubscribeActivity, getRecentActivity, push events).
+- Client: add ChangeStreamService (TypedSocket connection, reconnection, RxJS subjects) and integrate into tsview-app, mongo and S3 browsers to show live status, change counters and refresh content on updates.
+- UI: add new Activity Stream component (tsview-activity-stream), Activity tab and navigation, plus visual indicators (Live/Offline, change badges, auto-scroll and filters).
+- Dependencies & plugins: add @api.global/typedsocket and @push.rocks/smartrx, bump @push.rocks/smartbucket; expose smartrx/typedsocket in plugins for server and web bundles.
+- Docs: update readme.hints.md with Real-Time Streaming architecture, interfaces and dependency notes.
+
+## 2026-01-25 - 1.4.0 - feat(web)
+
+add database overview panel, collection overview and resizable panels; show/hide system databases; use code editor with change-tracking in document view; add getDatabaseStats API and typings; enable overwrite for S3 uploads
+
+- Add backend handler getDatabaseStats + request/response typings (IReq_GetDatabaseStats, IDatabaseStats) and ApiService.getDatabaseStats()
+- New UI component tsview-mongo-db-overview to show database statistics (collections, objects, avg size, data/storage size, indexes)
+- Collections list: added an "Overview" entry that opens the DB overview when selected
+- Sidebar: context menu option to show/hide system databases (admin/config/local) and database collapse-on-click behavior
+- Resizable layout improvements: draggable dividers added for sidebar, Mongo editor panel and S3 preview panel (persisted via local state variables)
+- Document editor: switch to dees-input-code, track original content and unsaved changes, add discard/save flow and improved save handling
+- S3 handlers: fastPut calls now pass overwrite: true to allow replacing existing keys
+- Minor dependency bumps: @git.zone/tstest and @design.estate/dees-catalog
+
+## 2026-01-25 - 1.3.0 - feat(s3)
+
+add S3 create file/folder dialogs and in-place text editor; export mongodb plugin
+
+- Add mongodb dependency and export mongodb in ts/plugins.ts so ObjectId can be reused from plugins.
+- Update handlers.mongodb to use plugins.mongodb.ObjectId instead of requiring mongodb directly.
+- UI: Add create-file and create-folder dialogs and context-menu entries in tsview-app, tsview-s3-columns, and tsview-s3-keys to create objects (folders use a .keep object).
+- Implement client-side helpers to determine content type/default content and call apiService.putObject with base64 content when creating files/folders.
+- S3 preview: embed dees-input-code editor for text files with language detection, unsaved-changes indicator, Save/Discard flows, and saving via apiService.putObject.
+- Various styling and UX improvements for dialogs, buttons, and editor states.

 # tsview - Project Hints
 
 ## Overview
+
 tsview is a CLI tool for viewing S3 and MongoDB data through a web UI.
 
 ## Key Patterns
 
 ### Configuration
+
 - Reads from `.nogit/env.json` (created by `gitzone service`)
 - Environment variables: MONGODB_URL, S3_HOST, S3_ACCESSKEY, etc.
 
 ### CLI Commands
+
 - `tsview` - Start viewer (auto-finds free port from 3010+)
 - `tsview --port 3000` - Force specific port
 - `tsview s3` - S3 viewer only
 - `tsview mongo` - MongoDB viewer only
 
 ### Dependencies
+
 - Uses `@push.rocks/smartbucket` for S3 operations
 - Uses `@push.rocks/smartdata` for MongoDB operations
 - Uses `@api.global/typedserver` + `@api.global/typedrequest` for API
 - Uses `@design.estate/dees-catalog` for UI components
 
 ### Build Process
+
 - Run `pnpm build` to compile TypeScript and bundle web UI
 - UI is bundled from `ts_web/` to `ts/bundled_ui.ts` as base64
 
 ### Web UI Structure
+
 - `ts_web/elements/` - Web components (LitElement-based)
 - `ts_web/services/` - API service for backend communication
 - `ts_web/utilities/` - Shared formatting functions (formatSize, formatCount, getFileName)
 - `ts_web/styles/` - Shared CSS custom properties (themeStyles)
 
 ### TypedRequest Pattern
+
 ```typescript
 // Interface definition
 export interface IReq_ListBuckets extends plugins.typedrequest.implementsTR<
@@ -53,3 +60,53 @@ typedrouter.addTypedHandler(

 );
 ```
+
+## Real-Time Streaming (v1.5.0+)
+
+### Architecture
+
+- `ts/streaming/` - Backend streaming infrastructure
+  - `classes.changestream-manager.ts` - Manages MongoDB and S3 watchers
+  - `interfaces.streaming.ts` - TypedRequest interfaces for subscriptions
+- `ts_web/services/changestream.service.ts` - Frontend WebSocket client
+
+### MongoDB Change Streams
+
+- Uses native MongoDB Change Streams via `SmartdataDb.mongoDbClient`
+- Subscription per collection: `db/collection`
+- Events: insert, update, delete, replace, drop
+
+### S3 Change Detection
+
+- Uses `@push.rocks/smartbucket` BucketWatcher (polling-based)
+- Polling interval: 5 seconds
+- Events: add, modify, delete
+
+### Frontend Components
+
+- `tsview-activity-stream.ts` - Combined activity view with filtering
+- MongoDB/S3 browsers auto-subscribe to current resource
+- Visual indicators for "Live" status and recent change count
+
+### Key Streaming Interfaces
+
+```typescript
+// Subscribe to collection changes
+IReq_SubscribeMongo: { database, collection } -> { success, subscriptionId }
+
+// Subscribe to bucket changes
+IReq_SubscribeS3: { bucket, prefix? } -> { success, subscriptionId }
+
+// Subscribe to activity stream (all changes)
+IReq_SubscribeActivity: {} -> { success, subscriptionId }
+
+// Server pushes changes to subscribed clients
+IReq_PushMongoChange: { event: IMongoChangeEvent } -> { received }
+IReq_PushS3Change: { event: IS3ChangeEvent } -> { received }
+IReq_PushActivityEvent: { event: IActivityEvent } -> { received }
+```
+
+### Dependencies Added
+
+- `@api.global/typedsocket` - WebSocket client/server
+- `@push.rocks/smartrx` - RxJS utilities

+### How It Works
+
+1. **Backend** — A `TypedServer` serves the bundled web UI and exposes a typed API via `TypedRequest` over HTTP. A `TypedSocket` WebSocket layer handles real-time streaming subscriptions.
+
+2. **Frontend** — LitElement-based web components communicate with the backend via `TypedRequest`. The `ChangeStreamService` connects over WebSocket and distributes real-time events to active views via RxJS Subjects.
+
+3. **Streaming** — The `ChangeStreamManager` creates MongoDB Change Streams and S3 BucketWatchers on demand (one per subscribed resource). Changes are pushed to subscribed clients and accumulated in a 1000-event ring buffer for the Activity Stream view.
