The upstream provider has started a new channel called fastrack. It is detailed here (see the whole thread):
https://www.redhat.com/archives/nahant-list/2006-April/msg00001.html
CentOS will also build the fastrack SRPMS. We have created separate repositories in CentOS-3 and CentOS-4 called fasttrack. (I know the spelling is different, that is by design. We don't want to use the name of the upstream provider's program. Same as our use of CSGFS for Cluster Suite / Global File System, and not the upstream acronyms.)
The purpose of the CentOS-FastTrack repo is to provide Bugfix and Enhancement updates for people who choose to do these updates BETWEEN the point releases.
For example, there are currently 7 SRPMS that have been built for the CentOS-4 fasttrack repo ... they are here:
http://mirror.centos.org/centos/4/fasttrack/SRPMS/
These changes (or maybe newer ones for those packages) will be rolled into the CentOS-4.4 when the time comes.
What fasttrack will do is level out the update cycle for those who want to do bugfix and enhancement updates that way ... the packages are fully tested and part of the CentOS tree.
If you want to get the latest bugfix and enhancement updates as soon as they are available, you can use the fasttrack repo. If you want your bugfix and enhancements to happen exactly as they do now (at point release time), don't use the fasttrack repo. Security updates will continue to happen as they do now. ------------------
To enable the fasttrack repo for CentOS-4, save this .repo file:
http://mirror.centos.org/centos/4/fasttrack/CentOS-fasttrack.repo
to your /etc/yum.repos.d/ directory.
----------------
To enable fasttrack for CentOS-3, you will need to add an entry in your /etc/yum.conf file. See this Readme for instructions on that entry:
http://mirror.centos.org/centos/3/fasttrack/Readme.txt
Before anyone asks ... CentOS-3.7 is in progress; therefore, the CentOS-3 fasttrack repo is currently not populated. If will be populated shortly after CentOS-3.7 is released.

CentOS does not CONTAIN the upstream provider's product and is not affiliated in any way with the upstream provider or their products. CentOS is built from publicly available, open source SRPMS. If you have any questions ... see these links:
