Dashboard: new Syncfusion card layout, global stats, filters, health bars, active event display, client details, bulk restart, 15s auto-refresh, manual refresh toasts
API: standardized responses to camelCase; added serializers.py and updated events endpoints
Time: ensured UTC storage; frontend appends 'Z' for parsing and displays local time
Docs: updated copilot-instructions.md, README.md, TECH-CHANGELOG.md
Program Info: bumped to 2025.1.0-alpha.12 with user-facing changelog
BREAKING: external API consumers must migrate field names from PascalCase to camelCase.
Add Settings → Events (Presentations) defaults (interval, page-progress,
auto-progress) persisted via /api/system-settings
Seed defaults in init_defaults.py (10/true/true)
Add Event.page_progress and Event.auto_progress (Alembic applied)
CustomEventModal applies defaults on create and saves fields
Scheduler publishes only currently active events per group, clears retained
topics when none, normalizes times to UTC; include flags in payloads
Docs: update README, copilot instructions, and DEV-CHANGELOG
If you can split the commit, even better
feat(dashboard): add presentation defaults UI
feat(api): seed presentation defaults in init_defaults.py
feat(model): add Event.page_progress and Event.auto_progress
feat(scheduler): publish only active events; clear retained topics; UTC
docs: update README and copilot-instructions
chore: update DEV-CHANGELOG
README: Add System Settings API endpoints; describe new tabbed Settings layout with role gating; add Vite dev proxy tip to use relative /api paths.
Copilot instructions: Note SystemSetting key–value store in data model; document system_settings.py (CRUD + supplement-table convenience endpoint); reference apiSystemSettings.ts; note defaults seeding via init_defaults.py.
Program Info: Bump version to 2025.1.0-alpha.11; changelog explicitly tied to the Settings page (Events tab: supplement-table URL moved; Academic Calendar: set active period; proxy note); README docs mention.
No functional changes to API or UI code in this commit; documentation and program info only.
Dashboard
Add top-right user dropdown using Syncfusion DropDownButton: shows username + role; menu entries “Profil” and “Abmelden”.
Replace custom dropdown logic with Syncfusion component; position at header’s right edge.
Update /logout page to call backend logout and redirect to /login (reliable user switching).
Build/Config
Add @syncfusion/ej2-react-splitbuttons and @syncfusion/ej2-splitbuttons dependencies.
Update Vite optimizeDeps.include to pre-bundle splitbuttons and avoid import-analysis errors.
Docs
README: Rework Architecture Overview with clearer data flow:
Listener consumes MQTT (discovery/heartbeats) and updates API.
Scheduler reads from API and publishes events via MQTT to clients.
Clients send via MQTT and receive via MQTT.
Worker receives commands directly from API and reports results back (no MQTT).
Explicit note: MariaDB is accessed exclusively by the API Server; Dashboard never talks to DB directly.
README: Add SplitButtons to “Syncfusion Components Used”; add troubleshooting steps for @syncfusion/ej2-react-splitbuttons import issues (optimizeDeps + volume reset).
Copilot instructions: Document header user menu and splitbuttons technical notes (deps, optimizeDeps, dev-container node_modules volume).
Program info
Bump to 2025.1.0-alpha.10 with changelog:
UI: Header user menu (DropDownButton with username/role; Profil/Abmelden).
Frontend: Syncfusion SplitButtons integration + Vite pre-bundling config.
Fix: Added README guidance for splitbuttons import errors.
No breaking changes.
- Documented unified deletion process for single, single-in-series, and recurring series events
- Explained custom dialog interception of Syncfusion RecurrenceAlert and DeleteAlert
- Updated both README.md and .github/copilot-instructions.md to match current frontend logic
