## Unreleased (development workspace)
- Programminfo GUI regression/fix: `dashboard/public/program-info.json` could not be loaded in Programminfo menu due to invalid JSON in the new alpha.16 changelog line (malformed quote in a text entry). Fixed JSON entry and verified file parses correctly again.
- Dashboard holiday banner fix: `dashboard/src/dashboard.tsx` — `loadHolidayStatus` now uses a stable `useCallback` with empty deps, preventing repeated re-creation on render. `useEffect` depends only on the stable callback reference.
- Dashboard Syncfusion stale-render fix: `MessageComponent` in the holiday banner now receives `key={`${severity}:${text}`}` to force remount when severity or text changes; without this Syncfusion cached stale DOM and the banner did not update reactively.
- Dashboard German text: Replaced transliterated forms (ae/oe/ue) with correct Umlauts throughout visible dashboard UI strings — `Präsentation`, `für`, `prüfen`, `Ferienüberschneidungen`, `verfügbar`, `Vorfälle`, `Ausfälle`.
- TV power intent (Phase 1): Scheduler publishes retained QoS1 group-level intents to `infoscreen/groups/{group_id}/power/intent` with transition+heartbeat semantics, startup/reconnect republish, and poll-based expiry (`max(3 × poll_interval_sec, 90s)`).
- TV power validation: Added unit/integration/canary coverage in `scheduler/test_power_intent_utils.py`, `scheduler/test_power_intent_scheduler.py`, and `test_power_intent_canary.py`.
- Monitoring system completion: End-to-end monitoring pipeline is active (MQTT logs/health → listener persistence → monitoring APIs → superadmin dashboard).
- Monitoring API: Added/active endpoints `GET /api/client-logs/monitoring-overview` and `GET /api/client-logs/recent-errors`; per-client logs via `GET /api/client-logs/<uuid>/logs`.
- Dashboard monitoring UI: Superadmin monitoring page is integrated and displays client health status, screenshots, process metadata, and recent error activity.
- Bugfix: Presentation flags `page_progress` and `auto_progress` now persist reliably across create/update and detached-occurrence flows.
- Frontend (Settings → Events): Added Presentations defaults (slideshow interval, page-progress, auto-progress) with load/save via `/api/system-settings`; UI uses Syncfusion controls.
- Backend defaults: Seeded `presentation_interval` ("10"), `presentation_page_progress` ("true"), `presentation_auto_progress` ("true") in `server/init_defaults.py` when missing.
- Data model: Added per-event fields `page_progress` and `auto_progress` on `Event`; Alembic migration applied successfully.
- Event modal (dashboard): Extended to show and persist presentation `pageProgress`/`autoProgress`; applies system defaults on create and preserves per-event values on edit; payload includes `page_progress`, `auto_progress`, and `slideshow_interval`.
- Scheduler behavior: Now publishes only currently active events per group (at "now"); clears retained topics by publishing `[]` for groups with no active events; normalizes naive timestamps and compares times in UTC; presentation payloads include `page_progress` and `auto_progress`.
- Recurrence handling: Still queries a 7‑day window to expand recurring events and apply exceptions; recurring events only deactivate after `recurrence_end` (UNTIL).
- Logging: Temporarily added filter diagnostics during debugging; removed verbose logs after verification.
- WebUntis event type: Implemented new `webuntis` type. Event creation resolves URL from system `supplement_table_url`; returns 400 if not configured. WebUntis behaves like Website on clients (shared website payload).
- Settings consolidation: Removed separate `webuntis_url` (if present during dev); WebUntis and Vertretungsplan share `supplement_table_url`. Removed `/api/system-settings/webuntis-url` endpoints; use `/api/system-settings/supplement-table`.
- Scheduler payloads: Added top-level `event_type` for all events; introduced unified nested `website` payload for both `website` and `webuntis` events: `{ "type": "browser", "url": "…" }`.
- Frontend: Program info bumped to `2025.1.0-alpha.13`; changelog includes WebUntis/Website unification and settings update. Event modal shows no per-event URL for WebUntis.
- Documentation: Added `MQTT_EVENT_PAYLOAD_GUIDE.md` and `WEBUNTIS_EVENT_IMPLEMENTATION.md`. Updated `.github/copilot-instructions.md` and `README.md` for unified Website/WebUntis handling and system settings usage.
