DNF, the next-generation yum package manager spearheaded by the Fedora project, is now ready for end-user testing ahead of its expected use out-of-the-box by Fedora 22



From Phoronix:

The DNF package manager originally premiered as a non-default option in Fedora 18 and has quickly advanced with its new features and speed.

It's also been working to meet parity with Yum by supporting plug-ins, an external API, and other features.

DNF isn't expected to replace Yum until at least Fedora 22 in late 2014, but Hawkey package management is expected for Fedora 21. DNF builds upon the Hawkey library.
