+### 2025-01-06 - Session-Tracking implementiert
+- Neue Tabelle für Session-Verwaltung
+- Anzeige aktiver und beendeter Sessions
+- Manuelles Beenden von Sessions möglich
+- Dashboard zeigt Anzahl aktiver Sessions
+
+**Neue Features:**
+- **Sessions-Tabelle**: Speichert Session-ID, IP, User-Agent, Zeitstempel
+- **Aktive Sessions**: Zeigt alle laufenden Sessions mit Inaktivitätszeit
+- **Session-Historie**: Letzte 24 Stunden beendeter Sessions
+- **Session beenden**: Admins können Sessions manuell beenden
+- **Farbcodierung**: Grün (aktiv), Gelb (>5 Min inaktiv), Rot (lange inaktiv)
+
+**Geänderte/Neue Dateien:**
+- v2_adminpanel/init.sql (sessions Tabelle hinzugefügt)
+- v2_adminpanel/app.py (sessions() und end_session() Routen)
+- v2_adminpanel/templates/sessions.html (neu erstellt)
+- v2_adminpanel/templates/dashboard.html (Session-Statistik)
+- Alle Templates (Session-Navigation hinzugefügt)
+
+**Technische Details:**
+- Heartbeat-basiertes Tracking (last_heartbeat)
+- Automatische Inaktivitätsberechnung
+- Session-Dauer Berechnung
+- Responsive Tabellen mit Bootstrap
+
+**Hinweis:**
+Die Session-Daten werden erst gefüllt, wenn der License Server API implementiert ist und Clients sich verbinden.
