z/OS code modules changelog for 7.2 release

Monthly PTFs (Program Temporary Fixes) are available for Dynatrace z/OS components for 7.2 release through cumulative monthly maintenance, which is recommended for all 7.2 users.

To download the cumulative PTFs, JCL exists in the sample library that's created during the initial SMPE install (hilevel.LZDT72.SZDTSAMP). FTPMAINT and RFNMAINT facilitate downloads from a Dynatrace FTP server with RFNMAINT taking advantage of Receive from Network technology.

If you're using RFNMAINT, please update your JCL with the hash contained in the RFNINSTL job in the aforementioned link.
