Internal Use Only
1.5.2.0 ships 7.4.0.3 which doesn't have the "fix" for Bar Mitzvah but does have chsecurity which can set the SSL protocol level to 2 or 3 and avoid RC4 ciphers. When there is a Unified release with 7.4.0.4 in it, this bulletin can be updated to add the option of upgrade without chsecurity.
