CentOS 7 (1611) was released today. This is the CentOS version of the upstream Redhat 7.3. We expect to be upgrading our CentOS 7 servers some time within the next week. We are currently syncing our local mirros to catch up with the new release, and will then be doing some testing of the new release before upgrading production servers.
Update -- we are in the process of updating all of the CentOS 7 VPS servers -- you may see some very brief outages as we update and reboot the VPS systems.
