Daniel Mach z firmy Red Hat uvedl<\/a><\/noindex> o zah\u00e1jen\u00ed v\u00fdvoje spr\u00e1vce bal\u00ed\u010dk\u016f DNF 5, ve kter\u00e9m bude p\u0159evedena logika DNF implementovan\u00e1 v jazyce Python do knihovny libdnf napsan\u00e9 v C++.

Podpora Python API v DNF z\u016fstane, ale podnikov\u00e1 logika napsan\u00e1 v Pythonu bude p\u0159evedena do knihovny libdnf (C++), co\u017e zajist\u00ed shodnost fungov\u00e1n\u00ed spr\u00e1vce bal\u00ed\u010dk\u016f v distribuci.
