Aleš Kozumplík announced the release of DNF 0.6 today with the version bump coming as a result of some user sought after functionality.
The main feature of DNF 0.6.0 is support for advisory listings via the updateinfo sub-command to DNF. This drop-in replacement to Yum also now supports the include configuration directive and there's improvements to group operations. A handful of bugs were also fixed by this latest release.
