+v0.4.0 (2014-6-30)
+-----------
+* Optimize redis driver `compose_message`.
+* Add module skynet.harbor for monitor harbor connect/disconnect, see test/testharborlink.lua .
+* cluster.open support cluster name.
+* Add new api skynet.packstring , and skynet.unpack support lua string
+* socket.listen support put port into address. (address:port)
+* Redesign harbor/master/dummy, remove lots of C code and rewite in lua.
+* Remove block connect api, queue sending message during connecting now.
+* Add skynet.time()
+
+v0.3.2 (2014-6-23)
+----------
+* Bugfix : cluster (double free).
+* Add socket.header() to decode big-endian package header (and fix the bug in cluster).
+
+v0.3.1 (2014-6-16)
+-----------
+* Bugfix: lua mongo driver . Hold reply string before decode bson data.
+* More check in bson decoding.
+* Use big-endian for encoding bson objectid.
+
+v0.3.0 (2014-6-2)
+-----------
+* Add cluster support
+* Add single node mode
+* Add daemon mode
+* Bugfix: update lua-bson (signed 32bit int bug / check string length)
+* Optimize timer
+* Simplify message queue and optimize message dispatch
+* Use jemalloc release 3.6.0
+
+v0.2.1 (2014-5-19)
+-----------
+* Bugfix: check all the events already read after socket close
+* Bugfix: socket data in gate service 
+* Bugfix: boundary problem in harbor service
+* Bugfix: stdin handle is 0
+
+v0.2.0 (2014-5-12)
+-----------
+
+* Rewrite malloc hook , use `pthread_getspecific` instead of `__thread` to get current service handle.
+* Optimize global unique service query, rewrite `service_mgr` .
+* Add some snax api, snax.uniqueservice (etc.) , use independent protocol `PTYPE_SNAX` .
+* Add bootstrap lua script , remove some code in C .
+* Use a lua loader to load lua service code (and set the lua environment), remove some code in C.
+* Support preload a file before each lua serivce start.
+* Add datacenter serivce.
+* Add multicast api.
+* Remove skynet.blockcall , simplify the implement of message queue.
+* When dropping message queue (at service exit) , dispatcher will post an error back to the source of each message.
+* Remove skynet.watch , monitor is not necessary for watching skynet.call . so simplemonitor.lua is move to examples.
+* Remove the limit of global queue size (64K actived service limit before).
+* Refactoring `skynet_command`.
+
+v0.1.1 (2014-4-28)
+------------------
+
+* Socket channel should clear request queue when reconnect.
+* Fix the issue that socket close may block the coroutine.
+* Fix the issue that jemalloc api may crash on macosx (disable jemalloc on macosx).
+
+v0.1.0 (2014-4-23)
+------------------
+
+* First release version.
+
+First public version (2012-8-1)
+------------------
+
+* Make skynet from a private project to public.
