-# Release v3.0.14
+# Release v3.2.11
 
 ## Major Features
 
-**User Self-Service Capabilities**
-- **Restart Server**: Users can restart their running JupyterLab containers directly from the control panel without admin intervention
-- **Manage Volumes**: Selective reset of persistent volumes (home/workspace/cache) when server is stopped - users choose which volumes to reset via checkbox interface
+**Configuration-Agnostic Volume Management**
+- Volume list dynamically generated from `DOCKER_SPAWNER_VOLUMES` configuration
+- Optional `VOLUME_DESCRIPTIONS` dict for user-friendly volume descriptions
+- UI automatically adapts if volumes renamed, added, or removed in config
+- Template uses Jinja2 loop with conditional description display
+- Handler validates against `USER_VOLUME_SUFFIXES` from config
+
+**Admin Notification Broadcast**
+- Broadcast notifications to all active JupyterLab servers via `/hub/notifications`
+- Six notification types: default, info, success, warning, error, in-progress
+- 140-character message limit with live counter
+- Concurrent delivery using `asyncio.gather()` with 5-second timeout per server
+- Temporary API tokens (5-minute expiry) for authentication
+- Requires `jupyterlab_notifications_extension` on spawned servers
+
+**Privileged User Access Control**
+- Group-based docker.sock access via `docker-privileged` built-in group
+- Pre-spawn hook conditionally mounts `/var/run/docker.sock` based on group membership
+- Built-in group protection (auto-recreates if deleted)
+- Managed through JupyterHub admin panel at `/hub/admin`
 
 ## Technical Improvements
 
-**Frontend**
-- Bootstrap 5 modal compatibility (data-bs-toggle, data-bs-target, btn-close)
-- RequireJS module loading for proper JavaScript execution
-- Font Awesome icons (fa-rotate for restart, fa-database for volumes)
-- Proper template inheritance extending JupyterHub's default home.html
+**Configuration**
+- `jupyterhub_config.py` protected from import errors with `if c is not None:` guards
+- `DOCKER_SPAWNER_VOLUMES` defined as module-level constant (importable by handlers)
+- `get_user_volume_suffixes()` extracts volume suffixes from config
+- `USER_VOLUME_SUFFIXES` calculated and exposed to templates
 
-**Backend**
-- New API endpoint: `/api/users/{username}/manage-volumes` accepting JSON body with volume array
-- ManageVolumesHandler processes multiple volumes with detailed success/failure response
-- Manual permission checking (admin or self) for API handlers
-- Comprehensive logging for all operations (frontend console + backend logs)
+**Handlers**
+- `ManageVolumesHandler` validates against configured volumes (not hardcoded)
+- `BroadcastNotificationHandler` sends to `/jupyterlab-notifications-extension/ingest`
+- `NotificationsPageHandler` renders broadcast form
+- One-line logging per server: username, message preview, type, outcome
 
-**Infrastructure**
-- Version management system with project.env and auto-increment on build
-- Makefile enhancements: increment_version, tag, stop, logs targets
-- Docker API integration via /var/run/docker.sock for volume and container management
+**Templates**
+- Dynamic volume checkbox generation from `user_volume_suffixes`
+- Conditional description display from `volume_descriptions`
+- Bootstrap 5 modal syntax throughout
+- RequireJS wrapped JavaScript with CSRF protection
 
 ## Documentation
 
-- README updated with Features section and visual screenshots
-- CLAUDE.md created with architecture overview and configuration patterns
-- FEATURE_PLAN.md documenting implementation strategy
-- Journal tracking all substantive work
+**Modus Primaris Style**
+- README reorganized: features first, screenshots, then architecture
+- Simplified notification description (verbose → concise)
+- Simplified architecture diagram labels
+- Features as bullet points at top
+
+**New Documentation**
+- `doc/notifications.md` (35 lines) - notification system implementation
+- `doc/ui-template-customization.md` (58 lines) - template extension patterns
+- `doc/docker-socket-permissions.md` (66 lines) - socket access control
+
+**Screenshots**
+- `screenshot-home.png` - user control panel with restart and volume management
+- `screenshot-send-notification.png` - admin notification broadcast interface
+- `screenshot-volumes.png` - volume management modal
+- `screenshot-volumes-modal.png` - volume selection checkboxes
 
 ## Version History
 
-- **v3.0.14**: Documentation updates, 3-second stop delay
-- **v3.0.12**: Multi-volume management, Bootstrap 5 fixes, icons
-- **v2.11**: Previous stable release
+- **v3.2.11**: Configuration-agnostic volume management, optional descriptions
+- **v3.2.0**: Admin notification broadcast system
+- **v3.1.2**: Privileged user docker.sock access control
+- **v3.0.23**: Production readiness, CI/CD, architecture cleanup
+- **v3.0.14**: User self-service capabilities (restart, volume management)
 
 ## Upgrade Notes
 
-No breaking changes. Existing deployments will seamlessly adopt new self-service features upon container restart.
+No breaking changes. Configuration backward compatible.
 
-Users will see new buttons on the JupyterHub control panel:
-- "Restart Server" (when server is running)
-- "Manage Volumes" (when server is stopped)
+**Optional**: Add `VOLUME_DESCRIPTIONS` dict to `jupyterhub_config.py` for user-friendly volume descriptions in UI:
+```python
+VOLUME_DESCRIPTIONS = {
+    'home': 'User home directory files, configurations',
+    'workspace': 'Project files, notebooks, code',
+    'cache': 'Temporary files, pip cache, conda cache'
+}
+```
+
+**Optional**: Install `jupyterlab_notifications_extension` on spawned servers to enable admin notification broadcast.
+
+Existing deployments adopt new features upon container rebuild and restart.
