@@ -244,3 +244,4 @@ Das Projekt basiert auf bewährten Web-Standards:
     *   Bugfix ("Headers already sent"): Fehler beim Speichern im Artikel-Editor (`edit_article.php`) behoben, indem Output-Buffering hinzugefügt wurde.
 *   **Features:**
     *   Die Gewichts-Anzeige in der Rucksackübersicht (`backpacks.php`) wurde angepasst und zeigt nun das "Basisgewicht + Zusatzgewicht" in Klammern an anstatt nur dem Zusatzgewicht.
+    *   In der Rucksack-Bearbeitung (`edit_backpack.php`) kann nun der Besitzer des Rucksacks (analog zu Artikeln) innerhalb des Haushalts geändert werden.
