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_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: -

-General information -------------------- - -Based on community consensus, the 0MQ 3.1.x release reverts a number of -features introduced in version 3.0. 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. |
