+Update history
+==============
+
+Release 0.2.2 2012/4/6
+======================
+
+Improvements
+
+- Simpler interfaces at classifier, regression and recommender
+
+ - Clients are *NOT COMPATIBLE* with previous releases
+
+- Now mix works concurrently in multiple threads (except tf-idf counting)
+- Asynchronous RPC to multiple servers at once
+- Add --version option
+- Interface description language changed from C++-like to Annotated MessagePack-IDL
+- Minor error handling
+- A bit more tested than previous releases
+
+Bugfix
+
+ - #30, #29, #22
+
+Release 0.2.1 2012/3/13
+-----------------------
+
+Bugfix release: #28
+
+Release 0.2.0 2012/2/16
+-----------------------
+
+New Features
+
+- recommender
+
+ - support fast similar item search, real-time update, distributed data management
+ - inverted index : exact result, fast search
+ - locality sensitive hash : approximate result, fast search, small working space
+
+- regression
+
+ - online SVR using passive agressive algorithm
+ - as fast as current classifier
+
+- stat
+
+ - a Key(string)-Value(queue<double>)
+ - O(1) cost of getting sum, standard deviation, max, min, statistic moments for each queue
+
+- server framework
+
+ - less-tightly coupled distributed processing framework with each ML implementation
+ - idl & code generator - make it easy to write own jubatus system
+ - removed public release of client libraries (so easy to generate!)
+ - multiple mix - mutiple data objects can be mixed in one jubatus system
+
+Bugfix
+
+ - duplicate key entry in fv_converter breaks the parameter
