- Fix "Cannot use Ref after disposed" error in OIDC callback page
  - Store notifier reference before async gap
  - Add mounted check at start of processing
- Add proper SSO logout via Authentik end_session_endpoint

 ## [Unreleased]
 
+## [1.1.1] - 2026-01-04
+
+### Added
+- Logout now redirects to Authentik to end SSO session
+  - Clears local tokens AND invalidates Authentik session
+  - Uses OIDC end_session_endpoint from discovery document
+  - Redirects back to app after Authentik logout completes
+
+### Fixed
+- Fixed Riverpod lifecycle error in OIDC callback page
+  - "Cannot use the Ref of authProvider after it has been disposed"
+  - Store notifier reference before async gap to prevent disposed ref access
+  - Add mounted check at start of callback processing
+
+## [1.1.0] - 2026-01-04
+
+### Changed
+- **Dockerfile rebuild fix**: Added `flutter clean` before build to prevent stale cached artifacts
+  - VERSION build arg added for explicit cache busting
+  - Reordered build steps: clean → pub get → build_runner → health.json → flutter build
+  - Ensures deployed app always matches the version in health.json
+
+### Fixed
+- Replaced deprecated `dart:html` with `package:web` in iframe_view_web.dart
+  - Uses `web.HTMLIFrameElement` instead of `html.IFrameElement`
+  - Fixes deprecation warnings for Flutter 3.x web builds
+
+## [1.0.12] - 2026-01-04
+
+### Changed
+- Removed login page - auth now auto-initiates from AppScaffold
+  - No more redirect to /login, just auto-start OIDC if not authenticated
+  - Shows loading screen during auth, error screen on failure with retry
+  - Seamless experience when Authentik session exists
+
+### Removed
+- Removed /login route and _LoginPage widget
+
+## [1.0.11] - 2026-01-04
+
+### Changed
+- Web auth now extracts user info directly from JWT instead of syncing with core-api
+  - Eliminates CORS preflight issues with /auth/sync endpoint
+  - Decodes JWT claims (name, email, groups) client-side
+  - Bearer token will be used for API authentication
+
+## [1.0.10] - 2026-01-04
+
+### Fixed
+- Fixed OIDC callback route being redirected to login before processing
+  - Moved callback route exception check BEFORE the auth redirect check in router
+  - This was preventing token exchange from ever happening
+- Added favicon.ico to web root for proper browser tab icon display
+
 ## [1.0.9] - 2026-01-04
 
 ### Fixed
