varnish-5.0 has configuration changes, so the updated package has been pushed to rawhide, but will not replace the ones currently in EPEL nor in Fedora stable. Those who need varnish-5.0 for EPEL may use my COPR repos at https://copr.fedorainfracloud.org/coprs/ingvar/varnish50/. They include the varnish-5.0 and matching varnish-modules packages, and are compatible with EPEL 5, 6, and 7.
hitch-1.4.1 is configure file compatible with earlier releases, so packages for Fedora and EPEL are available in their respective repos, or will be once they trickle down to stable.
