23 - INCOMPATIBLE CHANGE: the node protocol used by this version is not
24 compatible to versions <2 - you have to upgrade all nodes.
25 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
26 and create a fully-meshed network with each other, normal nodes only
27 have to connect to seed nodes, other connections are on-demand.
28 - new "norc" and "force" options for MP::configure to ignore
29 or override the rc file.
30 - move seed code to Kernel.
31 - fixed small typo in MP::Transport.
32 - fix (unused) provider-kv (version sometimes missing).
33 - reduce the default export list of MP::Kernel.
34 - reduced various random delays to zero, as they
35 are hopefully no longer needed with the new global
36 protocol.
37 - do not use GMP for generating alphanumeric strings even when
38 available, use a more tricky algorithm instead.
39 - anonymous node names and remote port names have been shortened
40 considerably.
41 - aemp shell now supports "package" selection and offers an
42 $ECHO port you cna send messages to.
43 - rely on perl rand() instead of using /dev/urandom when available, as
44 hopefully it is random enough.
45 - aemp shell no longer leaks one port per command.
46
47 1.30 Thu Jun 30 11:30:39 CEST 2011
48 - connection errors at the right time would kill node
49 connections in a bad way (patch by Malcolm Studd).
50
51 1.29 Fri May 7 20:13:39 CEST 2010
52 - codename "Sadrak".
53 - fix error in callback at AnyEvent/MP/Global.pm line 339
54 (found by Sadrak).
55 - listener-less nodes had trouble sending keepalive
56 messages on write timeouts (found by Sadrak).
57 - the monitor guard could cause a memleak due
58 to autovivification if a mon was cleared after
59 the port was gone (analysed by Sadrak).
60 - do not overwrite the config file if we couldn't read it
61 for some reason (lesson demonstrated by Sadrak).
62
63 1.28 Thu Apr 1 21:23:54 CEST 2010
64 - accepted connections didn't correctly set up the SRCNODE
65 in some cases, leading to intra-node messages (such as monitoring)
66 to fail silently (great testcase by Sadrak).
67
68 1.27 Sat Mar 20 21:11:16 CET 2010
69 - avoid exceptions in the transport code if the connection
70 fails during TLS negotiation.
71 - delay new address broadcasts in seednodes, to reduce the
72 likelyhood of nodes connecting at the same time, leading to
73 message loss.
74 - improve general message passing efficiency by 8%, and special
75 case json framing for a 50% speed increase.
76 - add hints how to interface to aemp nodes from other programming
77 languages using the aemp protocol in AnyEvent::MP::Transport
78 (it can really be quite simple).
79 - handle unsupported remote framings more gracefully.
80
81 1.26 Wed Dec 30 16:48:37 CET 2009
82 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
83 all nodes need to upgrade.
84 - remote kil's did not work (reported by Eugene Grigoriev).
85 - documented monitor_timeout, connect_interval, auth_offer,
86 auth_accept, framing_format, autocork and nodelay options
87 and make them configurable via bin/aemp.
88 - some doc updates.
89 - remote kil's were not synchronous to message sends which affected
90 nobody, as remote kils were broken.
91 - remote mon/unmonitor requests were not synchronous to message
92 sends either sometimes, although it likely didnt matter.
93
94 1.24 Wed Dec 9 14:59:52 CET 2009
95 - codename "the foul egg".
96 - increased "unmonitored local port died" message level to 2, so
97 it is displayed by default now.
98 - generate random seed at configure time, not module loading time,
99 so fork&configure works as expected.
100 - decreased "seed"-related message priority in Global from 0 (d'oh)
101 to 9, as they are not signifcant.
102 - new experimental module AnyEvent::MP::DataConn to establish
103 additional data connections between nodes.
104 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
105 to call restart.
106 - bin/aemp setcert didn't properly handle the filename argument.
107 - removed empty and unused timeout= parameter from protocol greeting.
108
109 1.23 Fri Nov 6 18:46:26 CET 2009
110 - listener-less nodes were misinformed by their masters about
111 the location of new nodes, and therefore didn't connect
112 properly in all cases.
113 - messages send during node-up processing could sometimes get lost,
114 which would hamper global's ability to mesh the network.
115 - fixed AnyEvent::MP::Global::grp_reg to return a guard also
116 in scalar context.
117 - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
118 in scalar context.
119 - try to improve error reporting when automatically loading
120 a function - being unable to load a module will now
121 stop the process and report the error.
122
123 1.22 Sat Oct 17 03:41:47 CEST 2009
124 - fix two rcv-bugs: after adding a tagged rcv, the default
125 callback would not be used or changed anymore (reported
126 by Felix Antonius Wilhelm Ostmann, with apologies for
127 taking so long to releae the fix).
128 - added Coro::MP introduction to AnyEvent::MP::Intro.
129 - add peval function.
130
131 1.21 Mon Oct 5 21:58:36 CEST 2009
132 - always delay kil messages.
133 - remote monitor requests were never cleaned up (found by
134 Sadrak and analysed by elmex).
135 - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
136
137 1.2 Thu Oct 1 22:59:35 CEST 2009
138 - fix a rather big bug where message processing could be
139 inhibited completely.
140 - grp_mon could not return a guard due to a typo.
141 - implement primitive aemp shell.
142 - do not use bound address as listen length (reported by
143 Felix Antonius Wilhelm Ostman).
144 - no longer export an undefined "reg" function from AE::MP.
145 - the mon_guard return value no longer keeps an additional
146 reference to the passed refs.
147
148 1.1 Fri Sep 11 04:34:03 CEST 2009
149 - bumped the transport protocol to version 1 - sorry, but there
150 were too many bugfixes/changes.
151 - new function AnyEvent::MP::cal for simple rpc.
152 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
153 - implemented monitoring for Global groups.
154 - removed all userspace time-outs from the transport, instead
155 rely on tcp retransmit timeouts and tcp keepalive.
156 - spawn now delays spawns on the local node artificially, so
157 it can return before invoking the init function.
158 - break endless recursion between ping-pong ports on the local
159 node after ~50 iterations.
160 - support JSON-encoded aemp arguments.
161 - added aemp restart.
162 - support for starting init functions with parameters added.
163 - data_format, auth_offer and auth_accept are now configurable, albeit
164 not documented.
165 - new service: AnyEvent::MP::LogCatcher.
166 - rely on perl srand'ing better than we could.
167 - try to backport to 5.8.2, unfortunately, recursive dependencies
168 rely on Module::Build, which fails at 5.8.7, so YMMV.
169 - use a vastly different reseeding strategy.
170 - use seed nodes to notify nodes about new nodes.
171 - in the case where a ndoe learns new addresses after it tried
172 connecting, prefer the new addrseses over the old ones.
173
174 1.0 Wed Sep 2 20:40:43 CEST 2009
175 - randomise more connection times, but reduce delay to 0.2s (seeds)
176 and 0.05s (normal connects).
177 - upgrade to and require AnyEvent::Watchdog 1.0.
178
179 0.95 Mon Aug 31 22:03:55 CEST 2009
180 - tutorial finally covers all the basics, maybe not optimally, but it
181 is covered.
182 - rename initialise_node to configure and accepts key => value
183 pairs for configuration.
184 - give aemp a full manpage.
185 - bin/aemp now expects comma-separated lists and supports multiple
186 subcommands.
187 - new aemp eval subcommand.
188 - new aemp parent subcommand.
189 - nodes get freed when no longer needed.
190 - support "*" hostname to specify all local interface addresses
191 (without localhost etc.).
192 - support "*" port to specify a dynamically-assigned port (which
193 is the default now).
194 - fix per-transport memory leak.
195
196 0.9 Sat Aug 29 18:47:45 CEST 2009
197 - tutorial was updated to reflect the current API, but
198 does not touch monitoring yet.
199 - got rid of noderefs and slave nodes entirely, introduce
200 free-text node identifiers and anonymous nodes.
201 - document security issues with tls_anon method and introduce
202 optional tls_md6_64_256 method.
203
204 0.8 Wed Aug 19 07:54:50 CEST 2009
205 - added AnyEvent::MP::Global service.
206 - support "package::" names as service names.
207 - many, many, many bugfixes and tweaks.
208
209 0.7 Sat Aug 15 01:18:51 CEST 2009
210 - sorry, another major API simplification.
211 - greatly improved aemp configuration abilities.

217 - do away with .aemp-secret and use .perl-anyevent-mp as json config
218 file.
219 - introduce bin/aemp to configure nodes.
220 - too many changes to describe.
