+ - ovs-dpctl:
+ * New debugging commands "add-flow", "mod-flow", "del-flow".
+ - New syslog format, prefixed with "ovs|", to be easier to filter.
+ - RHEL: Removes the default firewall rule that allowed GRE traffic to
+ pass through. Any users that relied on this automatic firewall hole
+ will have to manually configure it. The ovs-ctl(8) manpage documents
+ the "enable-protocol" command that can be used as an alternative.
