Problem: regression in 4.2.3 needs to be fixed before 4.3

NEWS

-0MQ version 4.3.1 stable, released on 20xx/xx/xx
+0MQ version 4.2.5 stable, released on 20xx/xx/xx
 ================================================
 
-* The following DRAFT APIs have been marked as STABLE and will not change
-  anymore:
-  - ZMQ_MSG_T_SIZE context option (see doc/zmq_ctx_get.txt)
-  - ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE
-    socket options, for the corresponding GSSAPI features. Additional
-    definitions for principal name types:
-    - ZMQ_GSSAPI_NT_HOSTBASED
-    - ZMQ_GSSAPI_NT_USER_NAME
-    - ZMQ_GSSAPI_NT_KRB5_PRINCIPAL
-    See doc/zmq_gssapi.txt for details.
-  - ZMQ_BINDTODEVICE socket option (Linux only), which will bind the
-    socket(s) to the specified interface. Allows to use Linux VRF, see:
-    https://www.kernel.org/doc/Documentation/networking/vrf.txt
-    NOTE: requires the program to be ran as root OR with CAP_NET_RAW
+* Fixed #3018 - fix backward-incompatible change in the NULL auth
+                mechanism that slipped in 4.2.3 and made connections
+                with a ZAP domain set on a socket but without a working
+                ZAP handler fail. See ZMQ_ZAP_ENFORCE_DOMAIN and RFC27.
+
+* Fixed #3016 - clarify in zmq_close manpage that the operation will
+                complete asynchronously.
 
+* Fixed #3012 - fix CMake build problem when using LIBZMQ_WERROR and a
+                compiler other than GCC.
 
 0MQ version 4.2.4 stable, released on 2018/03/21

 The 'ZMQ_MSG_T_SIZE' argument returns the size of the zmq_msg_t structure at
 runtime, as defined in the include/zmq.h public header.
 This is useful for example for FFI bindings that can't simply do a sizeof().
