Sun Solaris 2.4 Upgrade from INFORMIX 5.05 to 5.06

I have a client who has been told, by a third party software developer, that an upgrade from INFORMIX Online 5.05 to 5.06 is required in order for stored procedures to work correctly. Since I don't have the software in hand, which would allow me to look at the release notes, can someone tell me the enhancement/bug fixes that are included in 5.06? Regards -- Robert J.
