+## v1.4.12 (2026-02-24)
+- **Fix**: Das Glocken-Icon sollte nun endgültig versteckt bleiben, wenn keine Benachrichtigungen aktiv sind (CSS-Kollision mit `.hidden` behoben).
+
+## v1.4.11 (2026-02-24)
+- **Feature**: Das Versionsmenü prüft nun im Hintergrund direkt beim Öffnen nach neuen Versionen und aktualisiert die Liste automatisch, selbst wenn eine veraltete Liste noch im Cache liegt.
+
+## v1.4.10 (2026-02-24)
+- **Fix**: Die Farben der Benachrichtigungs-Glocke wurden korrigiert: Sie ist nun gelb, während man auf ein Menü wartet, und wird grün, sobald eines verfügbar ist.
+
+## v1.4.9 (2026-02-24)
+- **Fix**: Das Glocken-Icon für Benachrichtigungen wird nun direkt beim Start (wenn Daten aus dem lokalen Cache geladen werden) korrekt angezeigt.
+
+## v1.4.8 (2026-02-24)
+- **Fix**: Die Benachrichtigungs-Glocke wird nun korrekt in Gelb dargestellt, wenn beobachtete Menüs verfügbar sind.
+- **Tools**: Fehler in Testskript behoben, der den CI/CD Build verlangsamt hat.
+
+## v1.4.7 (2026-02-24)
+- **Performance**: Die Bestellhistorie nutzt nun einen inkrementellen Delta-Cache anstatt immer alle Seiten von der API herunterzuladen, was die Ladezeiten für Vielbesteller enorm reduziert.
+
+## v1.4.6 (2026-02-24)
+- **Fix**: Die Umrandung für bereits bestellte Menüs der vergangenen Tage ist nun ebenfalls einheitlich violett statt blau.
+
 ## v1.4.5 (2026-02-24)
 - **Fix**: Doppelten Scrollbalken in der Versionen-Liste entfernt.
