    Deprecated CMS and SSL APIs; SSLv2 and SSLv3 Protocols

    What is being removed or changed

    z/OS 3.2 is planned to be the last release to support:

    •            Deprecated CMS APIs
    •            Deprecated SSL APIs
    •            SSLv2 and SSLv3 protocols

    These protocols and APIs have been deprecated by industry standards bodies and are no longer considered secure.

    Required customer migration or upgrade actions

    Customers must:

    •             Identify applications using deprecated CMS or SSL APIs
    •            Migrate applications to supported cryptographic APIs
    •            Update System SSL and AT‑TLS configurations to use modern TLS protocols

    Failure to update may prevent applications from running on releases beyond z/OS 3.2.
