+++ DETAILS

a)  MQ 9.2.3 introduced Streaming Queues
(Duplication of messages in IBM MQ, including Streaming Queues which were introduced in MQ 9.2.3 CD)
In MQ 9.2.3 CD (Continuous Delivery), the feature "Streaming Queues" was introduced.
This feature will NOT be added back to MQ 9.1.x nor MQ 9.2.0.x LTS (Long Term Support).
The MQ client applications do not know about this new feature (that is, there is nothing that they need to do - you can use MQ clients at older versions.
The MQ queue manager at 9.2.3 or later, is the one that will handle the replication of messages (when streaming queues is activated)
.
