As soon as you update it with current fixes ('yum update') you'll be on the current point release, which is CentOS 6.6 at the moment. As has been pointed out several times here, you should NOT assume you can just install individual fixes such as the latest openssl for the heartbeat fixes, and so forth, as these have only been tested running with ALL the latest packages, not every conceivable combination of component versions over the past 4 years or so. -- john r pierce 37N 122W somewhere on the middle of the left coast
