+  To use this, select "epoll" as the polling method in the build system.
+  Note for distributors: the wepoll source code is embedded and distributed.
+  It is licensed under the BSD-2-Clause and thus it is compatible with LGPL-3.0.
+  Note that, if selected at build time, the license text must be distributed
+  with the binary in accordance to the license terms. A copy can be found in
+  the repository: external/wepoll/license.txt

+* 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.
+  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
+
+* Many, many coding style and static analysis improvements.

+
+* Fixed #3005 - added documentation for new zmq_timers_* API.
+
+* Fixed #3222 - use /Z7 debug on Release builds too on Windows (CMake).
+
+* Fixed #3226 - possible PGM receiver crash.
