For instance, binding a + socket to 'ipc://@/tmp/tester' will not create a file associated with + the socket whereas binding to 'ipc:///tmp/tester' will create the file + /tmp/tester. See issue 567 for more information. + +* Added zmq_z85_encode and zmq_z85_decode to core libzmq API. + +* Added zmq_curve_keypair to core libzmq API. + +* Bumped library ABI version to 4:0:1. + +Bug fixes +--------- + +* Fixed some build/test errors on OS/X + Clang++. + +* Fixed LIBZMQ-565, typo in code. + +* Fixed LIBZMQ-566, dealer-to-router connections sometimes failing. + +* Fixed builds for AIX, MSVC 2008, OS/X with clang++, Solaris. + +* Improved CURVE handshake error handling. + + +0MQ version 4.0.0 (RC1), released on 2013/09/20 +=============================================== + +Major changes +------------- + +* New wire level protocol, ZMTP/3.0, see http://rfc.zeromq.org/spec:23. + Does not yet implement the SUBSCRIBE, CANCEL, PING, and PONG commands. + +* New security framework, from plain user+password to strong encryption, + see section below. See http://hintjens.com/blog:49 for a tutorial. + +* New ZMQ_STREAM socket type for working as a TCP client or server. See: + tests/test_stream.cpp. + +Improvements +------------ + +* You can now connect to an inproc:// endpoint that does not already + exist. This means inproc:// no longer needs careful set-up, but it may + break code that relied on the old behaviour. See: + tests/test_inproc_connect.cpp. + +* Libzmq now checks socket types at connection time, so that trying to + connect a 'wrong' socket type will fail. + +* New zmq_ctx_shutdown API method will shutdown a context and send ETERM + to blocking calls, without blocking. Use zmq_ctx_term to finalise the + process. + +* The regression test suite has been significantly extended and improved. + +* Contexts can now be terminated in forked child processes. See: + tests/test_fork.cpp. + +* zmq_disconnect now respects the linger setting on sockets. + +* New zmq_send_const API method to send constant data (without copying). + See: tests/test_inproc_connect.cpp. + +* Added CMake support for static libraries. + +* Added test cases for socket semantics as defined in RFCs 28, 29, 30, 31. + See: tests/test_spec_*.cpp. + +* New socket option, ZMQ_PROBE_ROUTER triggers an empty message on connect. + See: tests/test_probe_router.cpp. + +* New socket option, ZMQ_REQ_CORRELATE allows for correlation of replies + from a REP socket. See: tests/test_req_correlate.cpp. + +* New socket option, ZMQ_REQ_RELAXED, lets you disable the state machine + on a REQ socket, so you can send multiple requests without waiting for + replies, and without getting an EFSM error. See: + tests/test_req_relaxed.cpp. + +* New socket option, ZMQ_CONFLATE restricts the outgoing and incoming + socket buffers to a single message. See: tests/test_conflate.cpp. + +Deprecated Options +------------------ + +* ZMQ_IPV4ONLY deprecated and renamed to ZMQ_IPV6 so that options are + consistently "off" by default. + +* ZMQ_DELAY_ATTACH_ON_CONNECT deprecated, and renamed to ZMQ_IMMEDIATE. + See: tests/test_immediate.cpp. + +Security Framework +------------------ + +Based on new ZMTP wire level protocol that negotiates a security +"mechanism" between client and server before exchanging any other data. + +Security mechanisms are extensible. ZMTP defines three by default: + +* NULL - classic ZeroMQ, with no authentication. See + http://rfc.zeromq.org/spec:23. + +* PLAIN - plain-text username + password authentication. See + http://rfc.zeromq.org/spec:24. + +* CURVE - secure authentication and encryption based on elliptic curve + cryptography, using the Curve25519 algorithm from Daniel Bernstein and + based on CurveCP's security handshake. See http://rfc.zeromq.org/spec:25, + http://rfc.zeromq.org/spec:26, and http://curvecp.org. + +Authentication is done by pluggable "authenticators" that connect to libzmq +over an inproc endpoint, see http://rfc.zeromq.org/spec:27. + +Socket options to configure PLAIN security on client or server: + +* ZMQ_PLAIN_SERVER, ZMQ_PLAIN_USERNAME, ZMQ_PLAIN_PASSWORD. See + tests/test_security_plain. + +Socket options to configure CURVE security on client or server: + +* ZMQ_CURVE_SERVER, ZMQ_CURVE_PUBLICKEY, ZMQ_CURVE_SECRETKEY, + ZMQ_CURVE_SERVERKEY. See tests/test_security_curve.cpp. + +Socket options to configure "domain" for ZAP handler: + +* ZMQ_ZAP_DOMAIN, see tests/test_security_null.cpp. + +Support for encoding/decoding CURVE binary keys to ASCII: + +* zmq_z85_encode, zmq_z85_decode. + +Other issues addressed in this release +-------------------------------------- + +* LIBZMQ-525 Multipart upstreaming from XSUB to XPUB + + +0MQ version 3.2.4 stable, released on 2013/09/20 +================================================ + +* LIBZMQ-84 (Windows) Assertion failed: Address already in use at signaler.cpp:80 +* LIBZMQ-456 ZMQ_XPUB_VERBOSE does not propagate in a tree of XPUB/XSUB devices +* LIBZMQ-532 (Windows) critical section not released on error +* LIBZMQ-569 Detect OpenPGM 5.2 system library +* LIBZMQ-563 Subscribers sometimes stopped receiving messages (aka LIBZMQ-541) +* LIBZMQ-XXX Added support for Travis Continuous Integration +* LIBZMQ-XXX Several improvements to MSVC support + + +0MQ version 3.2.3 stable, released on 2013/05/02 +================================================ + +Issues addressed in this release +-------------------------------- + +* LIBZMQ-526 Assertion failure "Invalid argument (tcp_connecter.cpp:285)" +* LIBZMQ-446 Setting the DSCP bits by default causes CAP_NET_ADMIN error +* LIBZMQ-496 Crash on heavy socket opening/closing: Device or resource busy (mutex.hpp:90) +* LIBZMQ-462 test_connect_delay fails at test_connect_delay.cpp:80 +* LIBZMQ-497 Messages getting dropped +* LIBZMQ-488 signaler.cpp leaks the win32 Event Handle +* LIBZMQ-476 zmq_disconnect has no effect for inproc sockets +* LIBZMQ-475 zmq_disconnect does not sent unsubscribe messages + + +0MQ version 3.2.2 stable, released on 2012/11/23 +================================================ + +Issues addressed in this release +-------------------------------- + +* LIBZMQ-384 No meta data for ZMQ_EVENT_DISCONNECTED monitor event +* LIBZMQ-414 Error in ARM/Thumb2 assembly (atomic_ptr.hpp) +* LIBZMQ-417 zmq_assert (!incomplete_in) in session_base.cpp 228 +* LIBZMQ-447 socket_base_t::recv() packet loss and memory leak at high receiving rate +* LIBZMQ-448 Builds fail on older versions of GCC +* LIBZMQ-449 Builds fail on AIX +* LIBZMQ-450 lt-test_monitor: fails with assertion at test_monitor.cpp:81 +* LIBZMQ-451 ZMQ_ROUTER_MANDATORY blocks forever +* LIBZMQ-452 test_connect_delay.cpp:175:12: error: 'sleep' was not declared in this scope +* LIBZMQ-458 lt-test_router_mandatory fails with assertion at test_router_mandatory.cpp:53 +* LIBZMQ-459 Assertion failed: encoder (stream_engine.cpp:266 +* LIBZMQ-464 PUB socket with HWM set leaks memory +* LIBZMQ-465 PUB/SUB results in 80-90% of CPU load +* LIBZMQ-468 ZMQ_XPUB_VERBOSE & unsubscribe +* LIBZMQ-472 Segfault in zmq_poll in REQ to ROUTER dialog + + +0MQ version 3.2.1 (RC2), released on 2012/10/15 +=============================================== + +Issues addressed in this release +-------------------------------- + +* Fixed issue xxx -

The major reason for these changes is +improving backward compatibility with 0MQ 2.1.x. + +Development of the 0MQ 3.0.x series will be discontinued, and users are +encouraged to upgrade to 3.1. + +The 0MQ 3.1.x releases use ABI version 3. + +Reverted functionality +---------------------- + +The following functionality present in 0MQ 3.0 has been reverted: + +* Wire format changes. The 0MQ 3.1 wire format is identical to that of 0MQ + 2.1. + +* LABELs and COMMANDs have been removed. + +* Explicit identies are re-introduced, however they can be used only for + explicit routing, not for durable sockets. + +* The ZMQ_ROUTER and ZMQ_DEALER socket types are once again aliases for + ZMQ_XREQ and ZMQ_XREP. + +New functionality +----------------- + +* The zmq_getmsgopt() function has been introduced. + +* Experimental IPv6 support has been introduced. This is disabled by + default, see the zmq_setsockopt() documentation for enabling it. + +Other changes +------------- + +* The default HWM for all socket types has been set to 1000. + +* Many bug fixes. + +Building +-------- + +* The dependency on libuuid has been removed. + +* Support for building on Android, and with MSVC 10 has been added. + +0MQ version 3.0.0 (alpha), released on 2011/07/12 +================================================= + +New functionality +----------------- + +* A zmq_ctx_set_monitor() API to register a callback / event sink for changes + in socket state. + +* POSIX-compliant zmq_send and zmq_recv introduced (uses raw buffer + instead of message object). + +* ZMQ_MULTICAST_HOPS socket option added. Sets the appropriate field in + IP headers of PGM packets. + +* Subscription forwarding. Instead of filtering on consumer, the + subscription is moved as far as possible towards the publisher and + filtering is done there. + +* ZMQ_XPUB, ZMQ_XSUB introduced. Allow to create subscription- + forwarding-friendly intermediate devices. + +* Add sockopt ZMQ_RCVTIMEO/ZMQ_SNDTIMEO. Allow to set timeout for + blocking send/recv calls. + +* A new LABEL flag was added to the wire format. The flag distinguishes + message parts used by 0MQ (labels) from user payload message parts. + +* There is a new wire format for the REQ/REP pattern. First, the empty + bottom-of-the-stack message part is not needed any more, the LABEL + flag is used instead. Secondly, peer IDs are 32-bit integers rather + than 17-byte UUIDs. + +* The REQ socket now drops duplicate replies. + +* Outstanding requests & replies associated with a client are dropped + when the clients dies. This is a performance optimisation. + +* Introduced ZMQ_ROUTER and ZMQ_DEALER sockets. These mimic the + functionality of ZMQ_ROUTER and ZMQ_DEALER in 0MQ/2.1.x. Guarantees + backward compatibility for exsiting code. + +* Removed dependency on OS socketpair buffer size. No more asserts in + mailbox.cpp because of low system limit of sockepair buffer size. + +API improvements +---------------- + +* Obsolete constants ZMQ_UPSTREAM and ZMQ_DOWNSTREAM removed. Use + ZMQ_PUSH and ZMQ_PULL instead. + +* Timeout in zmq_poll is in milliseconds instead of microseconds. This + makes zmq_poll() compliant with POSIX poll() + +* ZMQ_MCAST_LOOP removed. There's no support for multicast over + loopback any more. Use IPC or TCP isntead. + +* zmq_send/zmq_recv was renamed zmq_sendmsg/zmq_recvmsg. + +* ZMQ_RECOVERY_IVL and ZMQ_RECOVERY_IVL_MSEC reconciled. The new option + is named ZMQ_RECOVERY_IVL and the unit is milliseconds. + +* Option types changed. Most of the numeric types are now represented + as 'int'. + +* ZMQ_HWM split into ZMQ_SNDHWM and ZMQ_RCVHWM. This makes it possible + to control message flow separately for each direction. + +* ZMQ_NOBLOCK renamed ZMQ_DONTWAIT. That makes it POSIX-compliant. + +Less is More +------------ + +* Pre-built devices and zmq_device() removed. Should be made available + as a separate project(s). + +* ZMQ_SWAP removed. Writing data to disk should be done on top of 0MQ, + on inside it. + +* C++ binding removed from the core. Now it's a separate project, same + as any other binding. + +Bug fixes +--------- + +* Many. + +Building +-------- + +* Make pkg-config dependency conditional. + +Distribution +------------ + +* Removed Debian packaging, which is now available at packages.debian.org + or via apt-get. + + +Older versions +============== + +* See NEWS in ZeroMQ 2.1.x repository at http://github.com/zeromq/zeromq2-1. |
