The Varnish Cache project recently released varnish-5.0, and Varnish Software released hitch-1.4.1. I have wrapped packages for Fedora and EPEL.
varnish-5.0 has VCL and configuration file changes, so the updated package has been pushed to Fedora 25 and 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 repositories 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 repositories, or will be once they trickle down to stable.
As always, feedback is warmly welcome. Please report via Red Hat’s Bugzilla or, while the packages are cooking in testing, Fedora’s Package Update System
