          hopefully it is random enough.
        - aemp shell no longer leaks one port per command.
        - nodenames can contain %-escapes such as %n or %u.
        - aemp now uses aemp/%n/%u as nodename.
        - configure supports "eval", a small perl snippet to initialsie a node,
          most useful in "aemp run eval ...".
        - known_nodes is gone, it has little value, use all_nodes as
          replacement.
        - lots of small change and improvements.
        - node_is_known has been removed.
        - TRACE now shows the portid on SND.
        - aggressively reduce number of external modules, to reduce
          memory usage for nodes.
        - rework most of the documentation.
        - clean up MP::Kernel exports.
        - include AnyEvent::MP in AnyEvent::MP::Kernel's @CARP_NOT to
          hopefully improve error messages.

1.30 Thu Jun 30 11:30:39 CEST 2011
	- connection errors at the right time would kill node
          connections in a bad way (patch by Malcolm Studd).

1.29 Fri May  7 20:13:39 CEST 2010
	- codename "Sadrak".
        - fix error in callback at AnyEvent/MP/Global.pm line 339
          (found by Sadrak).
	- listener-less nodes had trouble sending keepalive
          messages on write timeouts (found by Sadrak).
        - the monitor guard could cause a memleak due
          to autovivification if a mon was cleared after
          the port was gone (analysed by Sadrak).
        - do not overwrite the config file if we couldn't read it
          for some reason (lesson demonstrated by Sadrak).

1.28 Thu Apr  1 21:23:54 CEST 2010
	- accepted connections didn't correctly set up the SRCNODE
          in some cases, leading to intra-node messages (such as monitoring)
          to fail silently (great testcase by Sadrak).

1.27 Sat Mar 20 21:11:16 CET 2010
	- avoid exceptions in the transport code if the connection
          fails during TLS negotiation.
        - delay new address broadcasts in seednodes, to reduce the
          likelyhood of nodes connecting at the same time, leading to
          message loss.
        - improve general message passing efficiency by 8%, and special
          case json framing for a 50% speed increase.
	- add hints how to interface to aemp nodes from other programming
          languages using the aemp protocol in AnyEvent::MP::Transport
          (it can really be quite simple).
        - handle unsupported remote framings more gracefully.

1.26 Wed Dec 30 16:48:37 CET 2009
	- INCOMPATIBLE CHANGE: the high-level node protocol changed,
          all nodes need to upgrade.
	- remote kil's did not work (reported by Eugene Grigoriev).
        - documented monitor_timeout, connect_interval, auth_offer,
          auth_accept, framing_format, autocork and nodelay options
          and make them configurable via bin/aemp.
        - some doc updates.
        - remote kil's were not synchronous to message sends which affected
          nobody, as remote kils were broken.
        - remote mon/unmonitor requests were not synchronous to message
          sends either sometimes, although it likely didnt matter.

1.24 Wed Dec  9 14:59:52 CET 2009
	- codename "the foul egg".
	- increased "unmonitored local port died" message level to 2, so
          it is displayed by default now.
        - generate random seed at configure time, not module loading time,
          so fork&configure works as expected.
        - decreased "seed"-related message priority in Global from 0 (d'oh)
          to 9, as they are not signifcant.
	- new experimental module AnyEvent::MP::DataConn to establish
          additional data connections between nodes.
        - bin/aemp now loads AnyEvent::Watchdog::Util before trying
          to call restart.
        - bin/aemp setcert didn't properly handle the filename argument.
        - removed empty and unused timeout= parameter from protocol greeting.

1.23 Fri Nov  6 18:46:26 CET 2009
        - listener-less nodes were misinformed by their masters about
          the location of new nodes, and therefore didn't connect
          properly in all cases.
        - messages send during node-up processing could sometimes get lost,
          which would hamper global's ability to mesh the network.
        - fixed AnyEvent::MP::Global::grp_reg to return a guard also
          in scalar context.
        - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
          in scalar context.
        - try to improve error reporting when automatically loading
          a function - being unable to load a module will now
          stop the process and report the error.

1.22 Sat Oct 17 03:41:47 CEST 2009
	- fix two rcv-bugs: after adding a tagged rcv, the default
          callback would not be used or changed anymore (reported
          by Felix Antonius Wilhelm Ostmann, with apologies for
          taking so long to releae the fix).
	- added Coro::MP introduction to AnyEvent::MP::Intro.
	- add peval function.

1.21 Mon Oct  5 21:58:36 CEST 2009
	- always delay kil messages.
        - remote monitor requests were never cleaned up (found by
          Sadrak and analysed by elmex).
        - move $VERSION to AnyEvent::MP and AnyEvent::MP only.

1.2  Thu Oct  1 22:59:35 CEST 2009
        - fix a rather big bug where message processing could be
          inhibited completely.
	- grp_mon could not return a guard due to a typo.
	- implement primitive aemp shell.
        - do not use bound address as listen length (reported by
          Felix Antonius Wilhelm Ostman).
        - no longer export an undefined "reg" function from AE::MP.
        - the mon_guard return value no longer keeps an additional
          reference to the passed refs.

1.1  Fri Sep 11 04:34:03 CEST 2009
	- bumped the transport protocol to version 1 - sorry, but there
          were too many bugfixes/changes.
	- new function AnyEvent::MP::cal for simple rpc.
