dnf or Dandified Packaging Tool is the next-generation version of the Yellowdog Updater, Modified (yum), a package manager for .rpm-based distributions. DNF was introduced in Fedora 18, and it has been the default package manager for Fedora since version 22.
Perceived deficiencies of yum which DNF is intended to address include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver.
DNF performs package management tasks on top of RPM, and supporting libraries.
DNF was originally written in Python, but efforts are under way to port it to C and move most functionality from Python code into the new libdnf library. libdnf is already used by PackageKit, a Linux distribution-agnostic package system abstraction library, even though the library does not have most of DNF's features.

Adoption
DNF has been the default package manager for Fedora since version 22 which was released in May 2015. The libdnf library is used as a package backend in PackageKit. DNF is also available as an alternate package manager for Mageia Linux since version 6. It may become the default sometime in the future.
