I don't, but I watch the centos-announce list to see when important updates are 
released.  Our operations dept schedules all changes on a shared calendar so no 
one is surprised, although I can't recall a centos update ever causing a 
problem.  After doing a minor update on a non-production machine, I might just 
'ssh servername yum -y update' to a list of production servers.  For larger sets 
or point releases, I would first have done a 'yum install yum-downloadonly' on 
each server so I can 'ssh servername yum -y --downloadonly update' which can run 
unattended ahead of time, then when it is convenient to babysit the box, 
complete the update and reboot.  For point releases, be sure to read the release 
notes - there may be special instructions like the need to update glibc\* 
separately for 5.3.
