+## [1.12.0] – 2026-07-20
+
+### Hinzugefügt
+- Einzelne Tage als geschlossen markierbar (z. B. Feiertage,
+  Betriebsausflug) – im Wochenplan lässt sich pro Tag über „Tag
+  schließen" ein optionaler, mehrsprachiger Grund hinterlegen (inkl.
+  automatischer Übersetzung per DeepL, sofern konfiguriert). Ein
+  geschlossener Tag:
+  - blendet in der Gerichte-Verwaltung des Wochenplans „Mahlzeit
+    hinzufügen" für diesen Tag aus (bestehende Einträge lassen sich
+    weiterhin entfernen), lässt sich per „Wieder öffnen" jederzeit
+    rückgängig machen.
+  - zeigt auf der öffentlichen Speisekarte (Desktop-Tabelle und
+    mobile Ansicht) einen „Geschlossen"-Hinweis mit Grund statt der
+    Essenszeiten-Spalten/-Karte für diesen Tag.
+  - erscheint im RSS-Feed als eigener Eintrag mit Schließungsgrund
+    statt eines leeren oder fehlenden Tages.
+  - Neue Tabellen `closed_days`/`closed_day_translations` (Migration
+    `0007_closed_days.sql`).
