- Removed /callback route from Flutter router
- Removed _OidcCallbackPage widget
- Auth is now invisible - no Flutter UI during auth flow

 ## [Unreleased]
 
+## [1.1.7] - 2026-01-04
+
+### Removed
+- Removed `/callback` route from Flutter router - AuthController handles callback in main() before app starts
+- Removed `_OidcCallbackPage` widget - no visible auth UI needed
+
+## [1.1.6] - 2026-01-04
+
+### Changed
+- **Auth moved to standalone controller** - Handles OIDC completely outside Riverpod
+  - New `AuthController` runs in `main()` before `runApp()` - avoids provider lifecycle issues
+  - Handles callback, token exchange, and /auth/sync before app starts
+  - If auth not ready (redirecting), app doesn't start at all
+  - `AuthProvider` now just loads stored tokens (no async OIDC logic)
+  - Fixes "Cannot use Ref after disposed" errors from autoDispose providers
+
+## [1.1.5] - 2026-01-04
+
+### Fixed
+- Race condition in OIDC callback: AuthProvider.build() was initiating silent OIDC while the callback page was processing, causing PKCE state to be cleared. Now skips silent OIDC when on `/callback` route.
+
+## [1.1.4] - 2026-01-04
+
+### Fixed
+- Silent OIDC fallback: when `prompt=none` fails with `login_required` (no Authentik session), automatically fall back to regular OIDC flow to show login UI
+
+## [1.1.3] - 2026-01-04
+
+### Changed
+- **Web auth uses silent OIDC with JWT Bearer tokens**
+  - Uses `prompt=none` to silently obtain JWT when Authentik session exists (via NPM forward auth)
+  - Flutter sends Bearer token to core-api instead of relying on forward auth cookies
+  - Fixes cross-subdomain cookie issues between home.schweitz.net and api.schweitz.net
+  - Callback now syncs with `/auth/sync` to get user profile and roles from core-api
+  - API interceptor now adds Bearer token on web (previously skipped)
+
+## [1.1.2] - 2026-01-04
+
+### Changed
+- **Web auth simplified**: Skip Flutter OIDC on web - NPM forward auth handles it
+  - NPM authenticates at proxy level before app loads
+  - No more redundant OIDC redirect after NPM auth completes
+  - Fixes "Cannot use Ref after disposed" error from conflicting auth flows
+  - Mobile still uses Flutter OIDC flow
+
+### 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
+
+## [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
+- Fixed OIDC callback Riverpod state modification error
+  - Deferred callback processing to `addPostFrameCallback` to avoid modifying state during widget build
+
+## [1.0.8] - 2026-01-04
+
+### Changed
+- Switched from hash-based URLs (`/#/login`) to path-based URLs (`/login`)
+  - Required for OIDC callback to work correctly
+  - Uses conditional import to avoid breaking mobile/desktop builds
+
+## [1.0.7] - 2026-01-04
+
+### Fixed
+- Fixed OIDC PKCE state loss across browser redirect
+  - Code verifier and state now persist in sessionStorage instead of memory
+  - Prevents "No code verifier" error after Authentik redirect
+
+## [1.0.6] - 2026-01-04
+
+### Fixed
+- Fixed version generation in CI/CD builds
+- Removed generated files (version.g.dart, health.json) from git tracking
+- These files are now regenerated from pubspec.yaml during Docker build
+
 ## [1.0.5] - 2026-01-04
 
 ### Changed
