The packages that will become CentOS-6.7, as well as updates completed for CentOS-6.7 to date are now released into the CentOS-6.6 Continuous Release (CR) repository.
All packages except for the centos-release RPM are included.
The purpose of the CR repository is to make the built packages optionally available to users who opt in while we work on the CentOS-6.7 install tree and all the CentOS-6.7 install media and images.
Normally the full release follows the CR release in 7-14 days if you do not use the CR process.
For more info on the CR repository, see this link:
http://wiki.centos.org/AdditionalResources/Repositories/CR
If you want to enable CR on CentOS-6.6, use the command:
yum install centos-release-cr
You would then get the updates with the command:
yum upgrade
Users who choose to opt-in to this process can access the newly built packages, as soon as they are exported from the build system after some basic testing has been completed. They are less comprehensively reviewed in the QA validation stage than the full release (Note: "Less comprehensively" does not mean no QA testing ... it just means less than the full release).
Some packages, like the anaconda installer, routinely receive updates during the full QA process, and the final versions may be updated from the CR version.
Known issues: 1. sssd-common is no longer multilib in CentOS 6.7. If you have the 32bit sssd-common installed on your x86_64 system, you will need to remove it with yum remove sssd-common.i686 prior to updating.
2. The boost RPMs are built with cmake-2.8 and the configuration files produced cause issues building some source code. There are an upstream bugs here (which is likely NOT being fixed):
https://bugzilla.redhat.com/show_bug.cgi?id=849791 https://bugzilla.redhat.com/show_bug.cgi?id=1245805
and there are related CentOS issues found previously:
http://bugs.centos.org/view.php?id=8117
If you are using boost to create packages, you can use the switch:
"-DBoost_NO_BOOST_CMAKE=ON"
To build sources that exhibit this issue.
3. The satyr package from EPEL is newer than the version included in CentOS-6.7. The package from EPEL seems to work OK as well, but they are likely to remove it as it also conflicts with RHEL-6.7. We have not observed any negative impacts from this issue.
4. yum-plugin-downloadonly has been obsoleted by yum, and the functionality is now built into the default yum.
More information: 1. These CentOS packages are built from the RHEL-6.7 source code released by Red Hat on July 22, 2015. Please review the release and technical notes for that release here:
