Hi Folks,
The CR (https://wiki.centos.org/AdditionalResources/Repositories/CR) repository was released last week. We have regenerated all the CentOS 7 buildroots in CBS so you can build against the content that will make it into the next point-release of CentOS Linux.
Machines in ci.centos.org are available with CR as well so you may continue your testing.
We are currently in Point-release Freeze which means anything tagged for release will *NOT* get pushed out to mirror.centos.org and we will be holding new push requests until we have a GA point-release.
If there are any questions please find us here or in #centos-devel on Freenode.
Happy building and testing !
