+      The KDE Software Collection and KDE Plasma Workspaces&nbsp;4.14, which is the version to be included in Fedora&nbsp;21, have already been made available to users of Fedora&nbsp;20 through the Updates repository. However, the KDE spin of Fedora now uses <application>SDDM</application> as its new default display manager. <application>KDM</application>, which was the default display manager on Fedora&nbsp;20 and earlier, is still available for installation from the Fedora repositories.
