V edici Fedora 41 bylo navr\u017eeno p\u0159ej\u00edt na v\u00fdchoz\u00ed bal\u00ed\u010dkov\u00fd mana\u017eer DNF5. P\u016fvodn\u011b se pl\u00e1novalo prov\u00e9st p\u0159echod na DNF5 ve verzi Fedora 39, ale migrace byla odlo\u017eena kv\u016fli nedostatku n\u00e1stroj\u016f. I kdy\u017e \u00fapln\u00e1 parita ve funk\u010dnosti se star\u00fdm n\u00e1strojem dosud nebyla dosa\u017eena, v\u00fdvoj\u00e1\u0159i v\u011b\u0159\u00ed, \u017ee distribuce je p\u0159ipravena na migraci a chyb\u011bj\u00edc\u00ed funkce mohou b\u00fdt implementov\u00e1ny pozd\u011bji.
