RabbitMQ 3.11.15

Core Server

Enhancements

Operator policies now can define "ha-sync-mode", a classic mirrored \ 
queue setting. Note that classic mirrored queues are
deprecated and will be removed in RabbitMQ 4.0.

All users of CMQs should migrate to quorum queues or streams,
or a combination of both.
