The version of CRIU which is included with CentOS is updated with every minor CentOS release (at least at the time of writing this) since 7.2, but once the minor CentOS release is available CRIU is not updated anymore until the next minor release. To make it easier to use the latest version of CRIU on CentOS I am now also rebuilding the latest version in COPR for CentOS: https://copr.fedorainfracloud.org/coprs/adrian/criu-el7/.
To enable my CRIU COPR on CentOS following steps are necessary:
yum install yum-plugin-copr
yum copr enable adrian/criu-el7
And then the latest version of CRIU can be installed using
yum install criu.
