For Pieter. Thanks for making all of this possible.
"Tell them I was a writer.

A humanist. A father.
And many things.
But above all, a writer.
Thank You. :)"- Pieter Hintjens
🚀 This release introduces new APIs, but it is ABI compatible with
libzmq 4.1.2 and up.Note for ARM and SPARC users: an alignment problem in zmq_msg_t that could in
some cases and on some CPUs cause a SIGBUS error was solved, but it requires
a rebuild of your application against the 4.2.0 version of include/zmq.h.
To clarify, this change does not affect the internals of the library but only
the public definition of zmq_msg_t, so there is no ABI incompatibility.🔒 Security with Curve is now available by default thanks to Tweetnacl sources:
https://tweetnacl.cr.yp.to/index.html
🏗 Libsodium is still fully supported but has to be enabled with the build flag
📦 --with-libsodium. Distribution and package maintainers are encouraged to use
🔒 libsodium so that the security implementation can be audited and maintained
separately.🆕 New Context options:
- ZMQ_MAX_MSGSZ
- ZMQ_BLOCKY
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
🆕 New Socket options:
- ZMQ_HANDSHAKE_IVL
- ZMQ_SOCKS_PROXY
- ZMQ_XPUB_NODROP
- ZMQ_XPUB_MANUAL
- ZMQ_XPUB_WELCOME_MSG
- ZMQ_STREAM_NOTIFY
- ZMQ_INVERT_MATCHING
- ZMQ_HEARTBEAT_IVL
- ZMQ_HEARTBEAT_TTL
- ZMQ_HEARTBEAT_TIMEOUT
- ZMQ_XPUB_VERBOSER
- ZMQ_CONNECT_TIMEOUT
- ZMQ_TCP_MAXRT
- ZMQ_THREAD_SAFE
- ZMQ_MULTICAST_MAXTPDU
- ZMQ_VMCI_BUFFER_SIZE
- ZMQ_VMCI_BUFFER_MIN_SIZE
- ZMQ_VMCI_BUFFER_MAX_SIZE
- ZMQ_VMCI_CONNECT_TIMEOUT
- ZMQ_USE_FD
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
🆕 New CURVE helper function to derive z85 public key from secret key:
zmq_curve_public🆕 New cross-platform atomic counter helper functions:
zmq_atomic_counter_new, zmq_atomic_counter_set, zmq_atomic_counter_inc,
zmq_atomic_counter_dec, zmq_atomic_counter_value, zmq_atomic_counter_destroy
See doc/zmq_atomic_*.txt for details.🆕 New DRAFT APIs early-release mechanism. New APIs will be introduced early
🚀 in public releases, and until they are stabilized and guaranteed not to
🔄 change anymore they will be unavailable unless the new build flag
--enable-drafts is used. This will allow developers and early adopters to
✅ test new APIs before they are finalized.
NOTE: as the name implies, NO GUARANTEE is made on the stability of these APIs.
They might change or disappear entirely. Distributions are recommended NOT to
🏗 build with them.🆕 New socket types have been introduced in DRAFT state:
ZMQ_SERVER, ZMQ_CLIENT, ZMQ_RADIO, ZMQ_DISH, ZMQ_GATHER, ZMQ_SCATTER,
ZMQ_DGRAM
All these sockets are THREAD SAFE, unlike the existing socket types. They do
NOT support multipart messages (ZMQ_SNDMORE/ZMQ_RCVMORE).
ZMQ_RADIO, ZMQ_DISH and ZMQ_DGRAM also support UDP as transport,
👀 both unicast and multicast. See doc/zmq_udp.txt for more details.
🆕 New methods to support the new socket types functionality:
zmq_join, zmq_leave, zmq_msg_set_routing_id, zmq_msg_routing_id,
zmq_msg_set_group, zmq_msg_group
👀 See doc/zmq_socket.txt for more details.🆕 New poller mechanism and APIs have been introduced in DRAFT state:
zmq_poller_new, zmq_poller_destroy, zmq_poller_add, zmq_poller_modify,
zmq_poller_remove, zmq_poller_wait, zmq_poller_wait_all, zmq_poller_add_fd
zmq_poller_modify_fd, zmq_poller_remove_fd
and a new supporting struct typedef: zmq_poller_event_t
👍 They support existing socket type, new thread-safe socket types and file
descriptors (cross-platform).
📚 Documentation will be made available in the future before these APIs are declared
stable.🆕 New cross-platform timers helper functions have been introduced in DRAFT state:
zmq_timers_new, zmq_timers_destroy, zmq_timers_add, zmq_timers_cancel,
zmq_timers_set_interval, zmq_timers_reset, zmq_timers_timeout,
zmq_timers_execute
and a new supporting callback typedef: zmq_timer_fn🛠 Many, many bug fixes. The most important fixes are backported and captured in the
