+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.
