Keep in mind that to _not_ install an update, you have to know more
than the RH engineers about the code.  I usually assume they had a
good reason for going to the trouble of shipping it and that they
would have to have a very, very good reason to ship anything that
would break an existing API in an update.  Of course it is always good
policy to test the combination of things you run in production on a
non-critical box first.

How about just joining the centos-announce mail list?
