This section summarizes the changes to the CICS®-supplied utilities across supported CICS releases. Use this information to plan the impact of
upgrading from one release to another.
If you are upgrading from an end-of-service release,
you can find information about the changes that are relevant to those releases in Summary of changes from end-of-service releases.
Highlights of changes across supported releases of CICS TS
Table 1 lists changed utilities in each supported CICS TS release. The links take you to the relevant tables that describe changes to specific utilities by release.
Note: Dump utilities DFHDU
xxx and DFHPD
xxx and the CICS trace
utility print program DFHTU
xxx are renamed with a new release identifier every
release, so they are not specifically listed in
Table 1 unless they have other functional changes.
