    This APAR includes a new version of the standard installation
    defaults module ASMADOPT and the macro ASMAOPT used to build
    it.
    If the default options module has been customized, for example
    using USERMOD ML00001 as defined in the sample ASMAOPTS job,
    then the customization needs to be reapplied after installing
    this update in order to avoid reverting to standard defaults.
    
    The new instruction table Z17 (with alternative name ZSB) is
    updated to remove unsupported instructions.
