+## v1.4.31
+- 🐛 **Bugfix**: Der "Lokalen Cache leeren"-Button löscht nun gezielt nur noch Kantine-spezifische Daten (`kantine_` Präfix). Bisher wurde die gesamte `localStorage` geleert, was dazu führte, dass man auch aus der zugrundeliegenden bessa.app-Sitzung ausgeloggt wurde.
+
+## v1.4.30
+- 🐛 **Bugfix**: Login-Sitzung (`authToken` etc.) wird nun in der `localStorage` statt `sessionStorage` gespeichert, wodurch die Anmeldung beim Öffnen von Bookmarklets in neuen Tabs/Fenstern erhalten bleibt.
+- 🐛 **Bugfix**: Bestell-Erinnerungscountdown und Alarm-Notifications erscheinen nun nur noch für angemeldete Nutzer.
+
+## v1.4.29
+- 🐛 **Bugfix**: Favicon-Injection in `install.html` mit `setTimeout(0)` verzögert, sodass sie nach dem `document.write()` von htmlpreview.github.io läuft. Chrome erkennt Favicon-Änderungen erst im nächsten Event-Loop-Tick.
+
+## v1.4.28
+- 🎨 **Favicon**: Eigenes Favicon-Design aus `favicon_base.png` (2048x2048) auf 32x32 skaliert. Wird beim Build automatisch als PNG-Data-URI in Bookmarklet und Installer injiziert.
+
+## v1.4.27
+- 🔧 **Build**: Favicon wird jetzt sauber aus `favicon.png` per Build-Script als PNG-Base64-Data-URI generiert und über `{{FAVICON_DATA_URI}}` Platzhalter in `kantine.js` + `install.html` injiziert. Funktioniert auf allen Browsern und Proxy-Diensten.
+
+## v1.4.26
+- 🎨 **Favicon**: Von SVG-Base64 auf PNG-Datei (`favicon.png`) umgestellt, verlinkt via raw.githubusercontent.com. Funktioniert zuverlässig auf allen Browsern und Proxy-Diensten (htmlpreview.github.io).
+
+## v1.4.25
+- 🐛 **Bugfix**: Favicon wird in `install.html` jetzt zusätzlich per JavaScript injiziert, um Proxy-Dienste wie htmlpreview.github.io zu überschreiben. Release-Script pusht nun auch `main` Branch zu GitHub.
+
+## v1.4.24
+- 🐛 **Bugfix**: Favicon-Encoding korrigiert – `encodeURIComponent` verursachte doppeltes Encoding der Farbcodes (`%23` → `%2523`). Auf Base64 umgestellt, funktioniert nun auch unter Chrome/Windows.
+
+## v1.4.23
+- 🐛 **Bugfix**: Favicon wird jetzt beim Ausführen des Bookmarklets in die Seite injiziert (ersetzt das Bessa-Favicon im Tab). Chrome cached das Icon und übernimmt es anschließend auch in die Lesezeichenleiste.
+
 ## v1.4.22
 - 📝 **Docs**: Vollständiger Dokumentations-Audit: README.md um fehlende Dateien (favicon.svg, release.sh, Tests) und Features (Bestellhistorie, Version-Menü, Cache leeren, Favicon) ergänzt. REQUIREMENTS.md: Doppelte IDs (FR-090/091) behoben, FR-092 an dynamische Glow-Logik angepasst, FR-116 (Cache leeren) und FR-117 (Favicon) hinzugefügt, NFR-008 um DOM-Tests erweitert.
