> This release is the result of many months of work -- many bugs have been
> fixed but no doubt some new ones have been introduced so at this stage we
> consider this Beta quality. If you are starting a new project with 0MQ, we
> strongly recommend that you go with 2.1.0.

> Thanks to everyone who contributed to the release, especially Martin
> Sustrik for his hard work on the new socket shutdown semantics and Mikko
> Koppanen for refactoring the autoconf build system.

> The release notes follow this email; full details can of course be found in

> Note that at the moment the reference manual at http://api.zeromq.org/ is

> ================================================
>
> 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".
