+ The NNG based libraries are no longer included in the RMR packages.
+ This is considered a breaking change as NNG will not be supported by
+ default. It is still possible to build with RMR-NNG libraries, but
+ that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
+ Upgrading to 4.0.0 only means that the underlying transport mechanism
+ is limited only to SI95.
+
+ The rmr_rcv_specific() function has been deprecated as it was necessary
+ only for NNG and Nanomsg support. Its use should be discontinued.
