|
|
Migration Information:
|
|
- Ursprünglich: template_helpers.py, form_validation.py, advanced_tables.py,
|
|
drag_drop_system.py, realtime_dashboard.py
|
|
- Konsolidiert am: 2025-06-09
|
|
- Funktionalitäten: Templates, Forms, Tables, Drag&Drop, Dashboard, WebSockets
|
|
- Breaking Changes: Keine - Alle Original-APIs bleiben verfügbar
