The CentOS community is very happy to announce the availability of release 6.3 of their distribution
On a personal note, I hadn't noticed that centos was just out of the oven. I downloaded it and installed it on a vbox machine and started to fiddle with it in order to install hiphop... and started posting threads with problems related to building hphp on centos 6.3 in the forums. Hope people find them useful. Other than that, given that I'm a more debian/ubuntu sysadmin, I can attest that I haven't felt alienated at all by working on a rh-based distro. Nice job, guys!
