              new Scientific Linux Secure Boot key.

            If you do not use UEFI Secure Boot, no action is required.

KNOWN ISSUES

Firewall fails to apply when using iptables-services
            if you use iptables and ip6tables on the same system, systemd
            tries to start them at the same time - and one may fail to
            load.

libgpod
            Users of the EPEL libgpod package may need to run
             yum downgrade libgpod
            before running yum update

MATE and Cinnamon

               Cinnamon desktops as provided by EPEL-7.
            The exact causes are unclear.
