Released CentOS 7.2 (1511) with improved features

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.

Cloud : OpenStack full functional package are available in CentOS 7 and we can install in by running “yum install centos-release-openstack-liberty” This was completely tested with by RDO Project. Also they included AWS & docker images as well and plan to add Microsoft Azure Cloud in upcoming releases.

Virtualization : The included lots of virtualization and hypervisor technology projects such as Xen, oVirt, Docker with latest releases and you can install ovirt node by running “yum install centos-release-ovirt36” & KVM “yum install centos-release-qemu-ev”.

Storage : Storages are included into the main repos such as Gluster Project, Ceph, OpenAFS, SCST and you can install it by running “yum install centos-release-gluster37”.
