+## v1.6.8 (2026-03-06)
+- ⚡ **Performance**: Das JavaScript für das Kantinen-Bookmarklet wird nun beim Build-Prozess (via Terser) minimiert, was die Länge der injizierten URL spürbar reduziert.
+
+## v1.6.7 (2026-03-06)
+- 🎨 **Style**: Das neue Header-Logo (`favicon_base.png`) wird nun konsequent auf 40x40px generiert und gerendert.
+
+## v1.6.6 (2026-03-06)
+- 🎨 **Style**: Den Schatten und den hervorstehenden Karten-Effekt für bestellte Menüs an vergangenen Tagen komplett entfernt - verbleiben nun visuell flach und unaufdringlich wie nicht-bestellte Menüs.
+
+## v1.6.5 (2026-03-06)
+- ✨ **Feature**: Das `restaurant_menu` Icon im Header wurde durch das neue `favicon_base.png` Logo ersetzt, passend zur Textgröße skaliert.
+- 🎨 **Style**: Violette Umrahmung (Bestellt-Markierung) an vergangenen Tagen entfernt, um den Fokus auf aktuelle und zukünftige Bestellungen zu lenken.
+- 🎨 **Style**: Der Glow-Effekt für am heutigen Tag bestellte Menüs wurde intensiviert.
+
+## v1.6.4 (2026-03-05)
+- ✨ **Feature**: Sprach-Lexikon (DE/EN) massiv erweitert um österreichische Begriffe (Nockerl, Fleckerl, Topfen, Mohn, Most etc.) und gängige Tippfehler aus dem Bessa-System (trukey, coffe, oveb etc.).
+- 🧹 **Cleanup**: Sprach-Lexikon dedupliziert und alphabetisch sortiert für bessere Performance und Wartbarkeit.
+- 🐛 **Bugfix**: Trennung von zweisprachigen Menüs (`splitLanguage`) verbessert: Erfasst nun auch Schrägstriche ohne Leerzeichen (z.B. `Suppe/Soup`).
+- 🐛 **Bugfix**: Fehlerhafte Badge-Anzeige korrigiert (Variable `count` vs `orderCount`).
+
+## v1.6.3 (2026-03-05)
+- ✨ **Chore**: Slogan im Footer aktualisiert ("Jetzt Bessa Einfach! • Knapp-Kantine Wrapper • 2026 by Kaufis-Kitchen") und Footer-Höhe für mehr Platzierung optimiert.
+
+## v1.6.2 (2026-03-05)
+- ✨ **Feature**: Wochentags-Header (Montag, Dienstag etc.) scrollen nun als "Sticky Header" mit und bleiben am oberen Bildschirmrand haften.
+  - Das Layout clippt scrollende Speisen ordentlich darunter weg.
+  - Vollständiges Viewport-Scrolling: Das Layout nutzt nun die ganze Höhe aus (`100dvh`), wodurch Scrollbalken sauber am Rand positioniert sind.
+- 🐛 **Bugfix**: Probleme mit Bessa's default `overflow` Verhalten behoben, das `position: sticky` auf iOS/WebKit-Browsern blockierte.
+
+## v1.6.0 (2026-03-04)
+- ✨ **Feature**: Sprachfilter für zweisprachige Menübeschreibungen. Neuer DE/EN/ALL Toggle im Header ermöglicht das Umschalten zwischen Deutsch, Englisch und dem vollen Originaltext. Allergen-Codes werden in allen Modi angezeigt. Einstellung wird persistent gespeichert.
+
 ## 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.
