This policy has allowed us to upgrade to new minor releases with a
minimum of testing for critical systems and basically none for non-
critical systems. We would never upgrade for minor releases if this
changes. We do not have the resources to perform full regression
tests without having a very big carrot such as the new features a
major release contains.
