Hi all,

we're happy to announce the release of 0MQ version 2.0.8.

The new version is available now to download on the website, at:


This release is primarily a bugfix release intended to consolidate the many
fixes made since 2.0.7.

Highlights of the 2.0.8 release:

New functionality

* The ZMQ_SWAP functionality has now been implemented for all socket types.

Bug fixes

* Many bug fixes (about 30), see the ChangeLog for details.


* zmq_device(3) is now documented and describes the built-in devices.

* The ZMQ_XREQ and ZMQ_XREP socket types are now documented in zmq_socket(3).


* By popular demand, the zmq_stopwatch_start, zmq_stopwatch_stop and zmq_sleep
  functions have been added back into distribution.  This API is now in a
  separate include file, zmq_utils.h.

* The ZMQ_UPSTREAM and ZMQ_DOWNSTREAM socket types have been renamed to
  ZMQ_PULL and ZMQ_PUSH for clarity.  The old names are still defined for
  compatibility reasons and will be removed in a future version.

* API calls that expect non-null parameters now return -1 and set errno to
  EFAULT if null parameters are passed.

Thanks to



Martin "mato" Lucina
