-* Evtl. wurden bei Änderungen in der Datenbank unnötigerweise einige Daten in Elwig doppelt angefordert. (cc018ded10)

-[v1.0.4.0][v1.0.4.0] (2026-03-16) {#v1.0.4.0}
---------------------------------------------
-
-### Neue Funktionen {#v1.0.4.0-features}
-
-* Im Lieferungen-Fenster (`DeliveryAdminWindow`) gibt es nun über die Menü-Leiste die Möglichkeit _Massenaktionen_ für mehrere Lieferungen durchzuführen (z.B. Attribut oder Zu-/Abschlag setzen). ([#78][i78])

-### Behobene Fehler {#v1.0.4.0-bugfixes}
-
-* Waagen mit Netzwerkschnittstelle versuchen die Verbindung nun wieder neu aufzubauen, sollte diese unterbrochen werden. ([#74][i74])
-
-### Sonstiges {#v1.0.4.0-misc}
-
-* Die bisher verwendeten Programm-Bibliotheken zum Erstellen von PDF-Dokumente wurden vollständig durch [iText](https://itextpdf.com/) ersetzt.
-  Das ermöglicht ein schnelleres, effizienteres, und stabileres Erstellen der PDF-Dokumente.
-  Außerdem konnte so die Größe der Installations-Datei von ~138 MB auf ~98 MB um ca. 30 % reduziert werden. (d8c967b2f2, 8054a024f4)
-* Abhängigkeiten aktualisiert. (af73226c90, f4fddd111f)
