I wanted to know what new features were available in different releases of MQ, but could not find the information documented.
I’ve taken the CMQC C header file from different releases on z/OS and shown the differences!
From MQ V8.0 to V9.0.1

Much of what you have listed is not so much new stuff in the MQI but new stuff in the PCF Admin interface. You might be interested in the following blog post (includes back links to the prior release equivalent ones) https://mqgem.wordpress.com/2020/12/08/whats-in-command-levels-92x/
I tend to also mention MQI changes since I notice them in the research I do to create the Command Level changes.

Morag,
You stuff looks very useful, thank you.
I worked on the differences, so I could tell which version of the MQCNO etc I should use with which version of MQ… I’m doing this in the pymqi Python interface code.
