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".
