    To discover the level of the internal PL/I compiler being used, a new command is available, SHOWPLI, from both batch and the Z Data Tools command line. See Customizing for processing PL/I include books for more information about submitting this command.
  • Z Data Tools provides the SHOWCOB command, from both batch and the Z Data Tools command line, to determine which COBOL compiler is being used, internal or external. When the Z Data Tools internal COBOL compiler is being used, more detailed messages are provided with this release to indicate why it is being used. See Customizing for processing COBOL copybooks for more information.
  • ZDT/Db2 IVP updates for supported versions of Db2 Version 12 and later. See the section Verifying the customization of ZDT/Db2 for the updates.
