+## 7. Mandatory Testing Policy 🧪
+**CRITICAL: No logic or UI fix is complete without a corresponding automated test.**
+- If you fix a regression or implement a new UI feature, you **MUST** write or update a test in `tests/test_dom.js` or `test_logic.js`. 
+- Refactoring MUST include verifying that no click listeners drop out. This guarantees that features like modal toggles stay functional.

+## v1.5.1 (2026-03-04)
+- 🐛 **Bugfix**: Freitagsbestellungen schlugen fehl ("Onlinebestellung sind nicht verfügbar"). Ursache: Der Order-Payload verwendete `preorder: false` und eine falsche Uhrzeit (`T10:00:00.000Z` statt `T10:30:00Z`). Beides wurde anhand der originalen Bessa-API korrigiert.
+
+## v1.5.0 (2026-02-26)
+Das große "Quality of Life"-Update! Zusammenfassung aller Features und Fixes seit v1.4.0:
+
+- ✨ **Bestellhistorie**: Übersichtliche Historie direkt in der App – gruppiert nach Jahr/Monat, inklusive Summen, Stati (Offen/Abgeschlossen/Storniert) und Delta-Cache für rasantes Laden.
+- ⚡ **Smart Cache & Performance**: Massive Reduzierung von API-Calls und Ladezeiten durch intelligenten lokalen Cache. Das Bookmarklet startet nun praktisch verzögerungsfrei.
+- 🔄 **GitHub Release Management**: In-App Versions-Menü mit Auto-Update Check (`🆕` Icon). Umschalten zwischen "Stable" und "Dev" Versionen sowie Downgrade-Möglichkeit direkt über die GitHub API.
+- 🌟 **Smart Highlights & UX**: Speisen-Favoriten leuchten nun im Design-Violett und erhalten Feature-Badges. Der Bestell-Badge für nächste Woche filtert nun intelligent personalisierte Highlights voraus.
+- 🔔 **Bestell-Warnung & Notifications**: Der System-Alarm berücksichtigt nun Sessions korrekt, zeigt dynamische Farbwechsel (gelb/grün/rot) und warnt verlässlich vor dem Bestellschluss (10:00 Uhr). Altlasten von Vortagen werden automatisch geputzt.
+- 🎨 **Eigenes Favicon**: Das Bookmarklet und der Installer haben nun ein eigenes Icon (Dreieck mit Besteck), das beim Hineinziehen in die Lesezeichenleiste übernommen wird (dynamisch generiert als lokales PNG).
+- 🧹 **Lokaler Cache-Clear**: Ein in das Versions-Menü eingebauter "Papierkorb", der ausschließlich fehlerhafte Kantinen-Caches putzt, ohne dabei versehentlich die aktive Bessa-Host-Session zu zerstören.
+- 🔒 **Sitzungs-Persistenz**: Die Login-Session überdauert jetzt neue Tabs, Fenster und Version-Upgrades reibungslos durch den Wechsel auf `localStorage`.
+- 🛡️ **Testing & Stabilität**: Vollautomatische DOM- und Logik-Testing-Suites in der Release-Pipeline integriert. Fehlerhafte UI-Buttons gehören der Vergangenheit an.
+
+
+## v1.4.0 (2026-02-22)
+- **Feature**: Bestellhistorie per Knopfdruck abrufbar. Übersichtliche Darstellung, gruppiert nach Monaten und Kalenderwochen, inklusive Stornos. 📜✨
+
 ## v1.3.2 (2026-02-19)
 - **Fix**: Falsche Anzahl an Highlight-Menüs im "Nächste Woche"-Badge korrigiert (zählte alle Menüs statt nur Highlights). 🐛
