The official Fedora Emacs 23 SRPM wasn’t submitted before the FeatureFreeze so it won’t be in F9. I’ll continue to track changes in the official Fedora emacs-22.2 packages and host new snapshot builds. If yum tried to upgrade emacs-22.2-4 over your emacs-23.0.60 installation, emacs-23.0.60-0.16.20080502cvs now fixes that problem by setting the epoch.
