 - A "sequence" notifier is added to ZeroMQ notifications, enabling client-side mempool
   tracking.
+- The same ZeroMQ notification (e.g. `-zmqpubhashtx=address`) can now be specified multiple
+  times to publish the same notification to different ZeroMQ sockets.

 The socket type is PUB and the address must be a valid ZeroMQ socket

+The same notification can be specified more than once.
 
 The option to set the PUB socket's outbound message high water mark
 (SNDHWM) may be set individually for each notification:
