+0MQ version 2.0.7 (Beta), released on 2010/06/XX
+================================================
+
+...
+
+0MQ version 2.0.6 (Beta), released on 2010/03/16
+================================================
+
+
+Distribution
+------------
+
+* The 0MQ core distribution has been slimmed down to include only the core
+ C library and C++ language binding. Pointers to other language bindings can
+ be found on the website. Examples have also been removed from the
+ core and can be found elsewhere. Performance tests specific to a language
+ binding can be found bundled with that language binding.
+
+* The 0MQ reference manual supplied with the distribution has been
+ extensively rewritten, and is now provided in HTML as well as UNIX
+ manpage format.
+
+* Commencing with this release, a 0MQ version numbering scheme has been
+ introduced. The numbering scheme used is MAJOR.MINOR.PATCH. The "Beta" or
+ "Stable" label is informative only and does not constitute
+ part of the library version number, therefore this release is numbered
+ 2.0.6 as the sixth release of 2.0.
+
+* The version of OpenPGM bundled with 0MQ has been updated to the stable
+ 2.0.24 release.
+
+
+Building
+--------
+
+* Many portability fixes, including support for new platforms: FreeBSD,
+ NetBSD, HP-UX and Cygwin.
+
+* Invocation of configure has been simplified, all functionality is now
+ built by default with the exception of OpenPGM.
+
+
+Interface
+---------
+
+* The udp transport has been renamed to epgm to avoid confusion with
+ unreliable unicast.
+
+* A ZMQ_POLLERR constant has been added to allow for polling on errors on
+ Berkeley sockets with zmq_poll().
+
+* The zmq_version() function has been introduced and returns the version
+ number of the 0MQ library.
+
+* The zmq_flush() function and ZMQ_NOFLUSH flag of zmq_send() have been
+ deprecated and will be removed in a future release.
+
+
+Wire format
+-----------
+
+* The 0MQ wire format has been changed. A flags field has been added to
+ allow for future extensions.
+
+
+New functionality
+-----------------
+
+* The experimental ZMQ_P2P socket type has been implemented.
+
+* Flow control has been implemented for all socket types. For details see
+ the ZMQ_HWM and ZMQ_LWM socket options.
+
+* Subscription filters are internally matched with O(1) complexity.
+
+
+Licensing
+---------
+
+* iMatix corporation has granted the following exception regarding static
+ linking with the 0MQ library:
+
+ As a special exception, iMatix gives you permission to link this
+ library with independent modules to produce an executable,
+ regardless of the license terms of these independent modules, and
+ to copy and distribute the resulting executable under terms of
+ your choice, provided that you also meet, for each linked
+ independent module, the terms and conditions of the license of
+ that module. An independent module is a module which is not
+ derived from or based on this library. If you modify this
+ library, you must extend this exception to your version of the
+ library.
+
+
+Thanks to
+---------
+
+This release of 0MQ was made possible by many contributors from the community,
+including:
+
+* Adrian von Bidder <avbidder@fortytwo.ch>, for contributing Debian packages.
+
+* Aleksey Yeschenko <aleksey@yeschenko.com>, for contributing a Lua binding.
+
+* Alessio Spadaro <alessio.spadaro@finservice.com>, for help with porting to
+ HP-UX.
+
+* Bernd Prager <bernd@prager.ws>, for help with porting to Cygwin.
+
+* Brian E. Granger <ellisonbg@gmail.com>, for maintaining the Python binding.
+
+* Martin Hurton <hurtonm@gmail.com>, for implementing flow control.
+
+* Martin Lucina <mato@kotelna.sk>, for rewriting the 0MQ reference manual and
+ many portability fixes.
+
+* Michael Santy <Michael.Santy@dynetics.com>, for testing this release with
+ Infiniband.
+
+* Steven McCoy <steven@miru.hk>, for help with OpenPGM.
+
+* Toralf Wittner <toralf.wittner@gmail.com>, for contributing a Haskell
+ binding.
