   - zmq_timers_* APIs. These functions can be used for cross-platforms timed
     callbacks. See doc/zmq_timers.txt for details.
 
+* The build-time configuration option to select the poller has been split, and
+  new API_POLLER (CMake) and --with-api-poller (autoconf) options will now
+  determine what system call is used to implement the zmq_poll/zmq_poller APIs.
+  The previous POLLER and --with-poller options now only affects the
+  internal I/O thread. In case API_POLLER is not specified, the behaviour keeps
+  backward compatibility intact and will be the same as with previous releases.
+
+* The non-default "poll" poller for the internal I/O thread (note: NOT for the
+  zmq_poll/zmq_poller user APIs!) has been disabled on Windows as WSAPoll does
+  not report connection failures. For more information see:

+* The pre-made Visual Studio solutions file are deprecated, and users are
+  encouraged to use the CMake solution generation feature instead.
 
 * New DRAFT (see NEWS for 4.2.0) socket options:
   - ZMQ_ROUTER_NOTIFY to deliver a notification when a peer connects and/or
     disconnects in the form of a routing id plus a zero-length frame.
+  - ZMQ_MULTICAST_LOOP to control whether the data sent should be looped back
+    on local listening sockets for UDP multicast sockets (ZMQ_RADIO).
   See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
