+- update to 4.3.5:
+  * Relicensing from LGPL-3.0+ (with custom exceptions) to MPL-2.0 is now complete.
+    libzmq is now distributed under the Mozilla Public License 2.0. Relicensing
+    grants have been collected from all relevant authors, and some functionality
+    has been clean-room reimplemented where that was not possible. In layman terms,
+    the new license provides the same rights and obligations as before. Source
+    files are now tagged using the SPDX license identifier format.
+    Details of the relicensing process can be seen at: #2376
+    Relicensing grants have been archived at:
+    https://github.com/rlenferink/libzmq-relicense
+    A special thanks to everybody who helped with this long and difficult task,
+    with the process, the reimplementations, the collections and everything else.
+  * New DRAFT (see NEWS for 4.2.0) socket options:
+    ZMQ_BUSY_POLL will set the SO_BUSY_POLL socket option on the underlying
+    sockets, if it is supported.
+    ZMQ_HICCUP_MSG will send a message when the peer has been disconnected.
+    ZMQ_XSUB_VERBOSE_UNSUBSCRIBE will configure a socket to pass all
+    unsubscription messages, including duplicated ones.
+    ZMQ_TOPICS_COUNT will return the number of subscribed topics on a
+    PUB/SUB socket.
+    ZMQ_NORM_MODE, ZMQ_NORM_UNICAST_NACK, ZMQ_NORM_BUFFER_SIZE,
+    ZMQ_NORM_SEGMENT_SIZE, ZMQ_NORM_BLOCK_SIZE, ZMQ_NORM_NUM_PARITY,
+    ZMQ_NORM_NUM_AUTOPARITY and ZMQ_NORM_PUSH to control various aspect of
+    NORM sockets.
+    See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
+  * New DRAFT (see NEWS for 4.2.0) zmq_ppoll APIs was added that differs from
+    zmq_poll in the same way that ppoll differs from poll.
+    See doc/zmq_ppoll.txt for details.
+  * Various bug fixes and performance improvements.
