From baf659fde5136c20f879ef713ec3effc34854ba6 Mon Sep 17 00:00:00 2001 From: Martin Lucina Date: Fri, 4 Jun 2010 17:12:51 +0200 Subject: Move news from ChangeLog into NEWS --- NEWS | 398 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 398 insertions(+) (limited to 'NEWS') diff --git a/NEWS b/NEWS index e69de29..40584b5 100644 --- a/NEWS +++ b/NEWS @@ -0,0 +1,398 @@ +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 , for contributing Debian packages. + +* Aleksey Yeschenko , for contributing a Lua binding. + +* Alessio Spadaro , for help with porting to + HP-UX. + +* Bernd Prager , for help with porting to Cygwin. + +* Brian E. Granger , for maintaining the Python binding. + +* Martin Hurton , for implementing flow control. + +* Martin Lucina , for rewriting the 0MQ reference manual and + many portability fixes. + +* Michael Santy , for testing this release with + Infiniband. + +* Steven McCoy , for help with OpenPGM. + +* Toralf Wittner , for contributing a Haskell + binding. +
