CentOS Project proudly announce the latest release of CentOS 7 (1511) on December 14, 2015 based on RHEL 7.2. I don’t know why the released little different version number CentOS 7 (1511) instead of CentOS 7.2. Still they are pulling updates to repository after froze the ISO. We can accomplish all the updated simply by running “yum update”.
This release included the Debuginfo packages which will install by default and this will help to get the issues & feedback from user to do R&D indepth for future releases.
Due to space & bandwidth constraints, They didn’t included LiveCD images. Also they advise us to use torrents to get initial installer images.
