There aren't any that I'm aware of, there are of course slight changes
in the CMS API since 2.x but nothing that should cause you problems.
This issue is a result of a change in the way KeepAlive messages are
sent from the broker in 5.3.0 and will be resolved in the next release
of CMS, for now you just need to either add that option to your client's
URI or change the configuration file for your broker to have the
following openwire connector config:

<transportConnectors>
   <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?transport.keepAliveResponseRequired=true"/>
</transportConnectors>
