Ben Cotton, kter\u00fd je programov\u00fdm mana\u017eerem Fedora v spole\u010dnosti Red Hat, ozn\u00e1mil z\u00e1m\u011br p\u0159est\u011bhovat Fedora Linux na v\u00fdchoz\u00ed spr\u00e1vce bal\u00ed\u010dk\u016f DNF5. V Fedora Linux 39 se pl\u00e1nuje zm\u011bnit bal\u00ed\u010dky dnf, libdnf a dnf-cutomatic na n\u00e1stroje DNF5 a novou knihovnu libdnf5. Tento n\u00e1vrh zat\u00edm nebyl projedn\u00e1n v\u00fdborem FESCo (Fedora Engineering Steering Committee), kter\u00fd zodpov\u00edd\u00e1 za technickou \u010d\u00e1st v\u00fdvoje distribuce Fedora. <\/p>\n
DNF byl ve sv\u00e9 dob\u011b n\u00e1hradou za Yum, kter\u00fd byl kompletn\u011b naps\u00e1n v jazyce Python. V DNF byly n\u00e1ro\u010dn\u00e9 n\u00edzko\u00farov\u0148ov\u00e9 funkce p\u0159epracov\u00e1ny a p\u0159esunuty do samostatn\u00fdch C knihoven hawkey, librepo, libsolv a libcomps, ale kostra a vysoce\u00farov\u0148ov\u00e9 komponenty z\u016fstaly v Pythonu. Projekt DNF5 si klade za c\u00edl unifikovat existuj\u00edc\u00ed n\u00edzko\u00farov\u0148ov\u00e9 knihovny, p\u0159epsat zbytek komponent spr\u00e1vy bal\u00ed\u010dk\u016f napsan\u00fdch v Pythonu do C++ a p\u0159esunout z\u00e1kladn\u00ed funk\u010dnost do samostatn\u00e9 knihovny libdnf5 s vytvo\u0159en\u00edm obal\u016f kolem t\u00e9to knihovny pro zachov\u00e1n\u00ed Python API. <\/p>\n
