+---------------------------------------------
+
+### 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)
