- Update to 2.2:
  * It is now possible to stop and restart an IvyServer, without recreating it.
    This is particularly useful for the std_api, where IvyStart() can be called
    again after IvyStop().
    Thanks to Jiri Borovec for reporting the problem.
- v2.1
  * ivyprobe.py is now declared as a runnable script and installed as such when
    installing or upgrading ivy-python
  * Fixed: an exception raised while connecting to a new agent which has just
    sent its initial UDP broadcast message was not handled, stopping the agent
    from listening to broadcast messages and as result, new agents connecting to
    the bus were ignored after this happened.  This is no longer the case:
    exceptions occuring while connecting to new clients (e.g. timeout) are
    logged but ignored, as expected.
  * Fixed std_api.IvyInit(): the default values for parameters on_cnx_fct and
    on_die_cnx were wrong
- v2.0
  * Signatures of ALL callbacks have been changed: 1st parameter passed to the
    callbacks is now *always* an IvyClient object, representing the agent
    whose message/behaviour triggered the callback.
    Example: a callback given to IvyBindMsg() was::
      def on_msg(*regexp_groups)
    must be changed to::
      def on_msg(agent, *regexp_groups)
    Based on an original patch by Olivier Saal who did most of the work, thanks
    Olivier.
    **IMPORTANT** Please note that this changes breaks backward compatibility:
                  agents coded for ivy-python v1.x must be adapted so that their
                  callbacks accept the new parameter.
- v1.2
  * The official subversion repository is now located at
    https://svn.tls.cena.fr/svn/ivy/
    Many thanks to the CENA team, and to Olivier Fourdan in particular,
    for setting up the global repository for ivy implementations.
  * New format of UDP broadcast messages, including the agent's id and name is
    now correctly handled.
    (cf. https://sympa.tls.cena.fr/wws/arc/ivy/2006-05/msg00004.html
     &   https://sympa.tls.cena.fr/wws/arc/ivy/2006-11/msg00010.html).
    Thanks to Olivier Saal for reporting.
  * Added examples/ivyprobe.py, a fully-featured ivyprobe in pure-python
  * Added: ivy.IvyClient.get_regexps() and std_api.IvyGetApplicationMessages()
  * Added: ivy.IvyClient.send_error() and std_api.IvySendError()
  * Added the ability to bind a callback for monitoring changes in other agents'
    subscriptions/bindings 
      stdapi: IvyBindRegexpChange()
      ivy: IvyServer.bind_regexp_change()
    Callback signature: on_regexp_change(client, event, regexp_id, regexp)
    where 
     - 'client' is an IvyClient object,
     - 'event' is either ivy.ivy.IvyRegexpAdded or IvyRegexpRemoved
  * Added the ability to bind a callback for direct messages
      stdapi: IvyBindDirectMsg()
      ivy:    IvyServer.bind_direct_msg()
    Callback signature: on_direct_msg_callback(client, num_id, msg)
    (where 'client' is an IvyClient object)
  * Fixed: stdapi.IvySendMsg() was not returning the number of peers to which
    the message was sent
  * Fixed: the UDP listening socket did not set the SO_REUSEPORT on systems where
    this flag is defined (such as: mac os x). On such systems, when more than one
    ivy-process was launched on the same bus, all processes but one failed with
    an error stating that the (udp broadcast) port was already in use.
