The CentOS-5.9 Packages for the i386 and x86_64 Architectures are now available via the Continuous Release (CR) Repository.
The CR Announcements for CentOS-5.9 can be viewed here:

More information about the CR Repository and how to install it is available here:

As explained in the above link, we are still doing advanced QA testing on CentOS-5.9 and there may be some minor changes before the final release. This "opt-in" CR Repo process allows earlier access to our best effort packages now while we complete the final CentOS-5.9 QA processes, spin the ISOs and create an installable tree.
