0MQ version 4.0.1 stable, released on 2013/10/08
================================================
Changes
-------
* Updated CURVE mechanism to track revised RFC 27 (INITIATE vouch).
The INITIATE command vouch box is Box[C',S](C->S') instead of
Box[C'](C->S), to reduce the risk of client impersonation, as per
https://codesinchaos.wordpress.com/2012/09/09/curvecp-1/.
* Fixed LIBZMQ-567, adding abstract namespaces for IPC sockets on Linux.
Converts an initial strudel or "at sign" (@) in the Unix socket path to
a NULL character ('\0') indicating that the socket uses the abstract
namespace instead of the filesystem namespace. 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

0MQ version 2.1.10 (Stable), released on 2011/10/03
===================================================
Bug fixes
---------
* Fixed issue 140, SWAP failed with assertion failure in pipe.cpp:187
if the current directory was not writeable. Behavior now is to return
-1 at zmq_setsockopt in this situation.
* Fixed issue 207, assertion failure in zmq_connecter.cpp:48, when an
invalid zmq_connect() string was used, or the hostname could not be
resolved. The zmq_connect() call now returns -1 in both those cases.
* Fixed issue 218, sockets not opened with SOCK_CLOEXEC, causing fork/exec
to sit on sockets unnecessarily.

used with explicit identities and multiple SUB sockets.
* Fixed issue 236, zmq_send() and zmq_recv() did not always return
error conditions such as EFSM properly. This bug was introduced in
version 2.1.8 by the backport of changes for issue 231.
Building
--------
* 0MQ support for Android added (Bill Roberts, Mikko Koppanen).
0MQ version 2.1.8 (RC), released on 2011/07/28
==============================================
Bug fixes
---------
* Fixed issue 223, assertion failure in tcp_connecter.cpp:300 when
connecting to a server that is on an unreachable network (errno is
equal to ENETUNREACH).
* Fixed issue 228, assertion failure at rep.cpp:88 when HWM was reached.
* Fixed issue 231, assertion failure at mailbox.cpp:183 when too many
pending socketpair operations were queued (major backport from 3.0).
* Fixed issue 234, assertion failure at mailbox.cpp:77 when Ctrl-C was
used (only affected git master following backport for 231).
* Fixed issue 230, SIGPIPE killing servers when client disconnected, hit

---------
* Fixed issue 191, message atomicity issue with PUB sockets (an old issue).
* Fixed issue 199 (affected ROUTER/XREP sockets, an old issue).
* Fixed issue 206, assertion failure in zmq.cpp:223, affected all sockets

due to abuse of assertions for error checking).
* Fixed issue 212, reconnect failing after resume from sleep on Windows
(due to not handling WSAENETDOWN).
* Properly handle WSAENETUNREACH on Windows (e.g. if client connects
before server binds).
Changes
-------
* Runtime checking of socket and context validity, to catch e.g. using a
socket after closing it, or passing an invalid pointer to context/socket
methods.
* Test cases moved off port 5555, which conflicts with other services.
* Clarified zmq_poll man page that the resolution of the timeout is 1msec.
0MQ version 2.1.6 (Stable), released on 2011/04/26
==================================================

multipart message to new subscribers (Martin Sustrik).
* Fix to PUB sockets, which would sometimes deliver tail frames of a
multipart message to new subscribers (Martin Sustrik).
* Windows build was broken due to EPROTONOSUPPORT not being defined. This

* Various fixes to make OpenVMS port work (Brett Cameron).
* Corrected Reference Manual to note that ZMQ_LINGER socket option may be
set at any time, not just before connecting/binding (Pieter Hintjens).
* Fix to C++ binding to properly close sockets (Guido Goldstein).
* Removed obsolete assert from pgm_socket.cpp (Martin Sustrik).

future upgrades of OpenPGM (Mikko Koppanen).
* Build system allows configuration with arbitrary versions of OpenPGM
(./configure --with-pgm=libpgm-x.y.z) (Mikko Koppanen).
* OpenPGM uses new PGM_ODATA_MAX_RTE controlling original data instead of
PGM_TXW_MAX_RTE covering entire channel (Steven McCoy).

explicit identities on inproc sockets.
* Various memory leaks were fixed.
* OpenPGM sender/receiver creation fixed.
0MQ version 2.1.1 (rc1), released on 2011/02/23
===============================================
New functionality
-----------------
* New socket option ZMQ_RECONNECT_IVL_MAX added, allows for exponential
back-off strategy when reconnecting.
* New socket option ZMQ_RECOVERY_IVL_MSEC added, as a fine-grained
counterpart to ZMQ_RECOVERY_IVL (for multicast transports).
* If memory is exhausted, 0MQ warns with an explicit message before
aborting the process.
* Size of inproc HWM and SWAP is sum of peers' HWMs and SWAPs (Douglas
Greager, Martin Sustrik).
Bug fixes
---------
* 0MQ no longer asserts in mailbox.cpp when multiple peers connect with
the same identity.
* 0MQ no longer asserts when rejecting an oversized message.
* 0MQ no longer asserts in pipe.cpp when the swap fills up.
* zmq_poll now works correctly with an empty poll set.
* Many more.
Building
--------
* 0MQ now builds correctly on CentOS, Debian 6, and SunOS/gcc3.
* Added WithOpenPGM configuration into MSVC builds.
Known issues
------------
* OpenPGM integration is still not fully stable.
0MQ version 2.1.0 (Beta), released on 2010/12/01
================================================
New functionality
-----------------
* New semantics for zmq_close () and zmq_term () ensure that all messages
are sent before the application terminates. This behaviour may be
modified using the new ZMQ_LINGER socket option; for further details
refer to the reference manual.
* The new socket options ZMQ_FD and ZMQ_EVENTS provide a way to integrate
0MQ sockets into existing poll/event loops.
* Sockets may now be migrated between OS threads, as long as the
application ensures that a full memory barrier is issued.
* The 0MQ ABI exported by libzmq.so has been formalised; DSO symbol
visibility is used on supported platforms to ensure that only public ABI
symbols are exported. The library ABI version has been set to 1.0.0 for
this release.
* OpenPGM has been updated to version 5.0.92. This version no longer
depends on GLIB, and integration with 0MQ should be much improved.
* zmq_poll() now honors timeouts precisely, and no longer returns if no
events are signaled.
* Blocking calls now return EINTR if interrupted by the delivery of a
signal; this also means that language bindings which previously had
problems with handling SIGINT/^C should now work correctly.
* The ZMQ_TYPE socket option was added; this allows retrieval of the socket
type after creation.
* Added a ZMQ_VERSION macro to zmq.h for compile-time API version
detection.
* The ZMQ_RECONNECT_IVL and ZMQ_BACKLOG socket options have been added.
Bug fixes
---------
* Forwarder and streamer devices now handle multi-part messages correctly.
* 0MQ no longer asserts when malformed data is received on the wire.
* 0MQ internal timers now work correctly if the TSC jumps backwards.
* The internal signalling functionality (mailbox) has been improved
to automatically resize socket buffers on POSIX systems.
* Many more.
Building
--------
* 0MQ now builds correctly with many more non-GCC compilers (Sun Studio,
Intel ICC, CLang).
* AIX and HP-UX builds should work now.
* FD_SETSIZE has been set to 1024 by default for MSVC builds.
* Windows builds using GCC (MinGW) now work out of the box.
Distribution
------------
* A simple framework for regression tests has been added, along with a few
basic self-tests. The tests can be run using "make check".
The 0MQ lightweight messaging kernel is a library which extends the
standard socket interfaces with features traditionally provided by
specialised messaging middleware products. 0MQ sockets provide an
abstraction of asynchronous message queues, multiple messaging
patterns, message filtering (subscriptions), seamless access to
multiple transport protocols and more.
