   included in the source tree under external/sha1/ - it is licensed
   under BSD-3-Clause and thus it is fully compatible with libzmq's
   license.
+  It is only used if WebSockets support is enabled, and if neither GnuTLS nor
+  NSS are available.
+
+* Note for packagers: an internal reimplementation of strlcpy is now included,
+  for wider platform compatibility.
+  libbsd can be used and is enabled by default if available instead of the
+  internal implementation, for better security maintenance in distros.
+
+* New DRAFT (see NEWS for 4.2.0) socket option:
+  - ZMQ_ONLY_FIRST_SUBSCRIBE will cause only the first part of a multipart
+    message to be processed as a subscribe/unsubscribe message, and the rest
+    will be forwarded as user data to the application.
+  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
+
+* New DRAFT (see NEWS for 4.2.0) zmq_ctx_get_ext/zmq_ctx_set_ext APIs were added
+  to allow enhancing the context options with variable data inputs.
+  See doc/zmq_ctx_get_ext.txt and doc/zmq_ctx_set_ext.txt for details.
+
+* New DRAFT (see NEWS for 4.2.0) transport options WS and WSS added for support
+  of WebSockets (and secure WebSockets via TLS) via the ZWS 2.0 protocol.
+  WSS requires the GnuTLS library for TLS support. ZMQ_WSS_ specific socket
+  options were added to support TLS.
+  WebSockets support can be disabled at build time with --disable-ws.
