----------------------------------------------
-
-### Sonstiges {#v1.1.1.2-misc}
-
-* In Matzen werden für Planenw./Kipper und Lesewagen die Klassen automatisch gesetzt. (3366cc25eb)
-* Im Lieferungen-Fenster (`DeliveryAdminWindow`) wird für "Nur heute" nicht mehr nur das Datum, sondern die letzten zusammenhängenden Lieferungen verwendet. (46e596ae23)
-* Für Pamhagen wird als standard Wiege-Methode "brutto" verwendet. (0c4611024f)
-* Für Waagen kann das automatische setzen von Datum und Uhrzeit nun per Opt-out ausgeschalten werden (Konfigurationsdatei -> `[scale.X]` -> `synctime = false`). (f450dc35b1)
-
-### Behobene Fehler {#v1.1.1.2-bugfixes}
-
-* Auf Lieferscheinen (`DeliveryNote`) waren die Mengenangaben nicht rechtsbündig. (ff71e9fb7f)
-* Beim Importieren von Mitgliedern mit Stamm-KG ohne Großlage kam es zu einem Fehler, obwohl die Großlage automatisch hätte zugewiesen werden müssen. (edf3678154)
