+Release 0.5.2 - 2011/04/23
+  NEW FEATURES
+    MSGPACK-6 Added TemplatePrecompiler program
+
+    Added built-in templates of BigDecimal and Date classes.
+
+    Added @MessagePackBeans annotation that enables you to serialize/deserialize
+    JavaBeans.
+
+  BUG FIXES
+    MSGPACK-4 Fixes the deserialization routine of Long value
+
+  IMPROVEMENTS
+    #35 Improves handling of ClassLoader on Javassist template builder.
+
+    MSGPACK-7 Improves compatibility with Java 1.5. Now it runs on JRE 5.
+    It is tested on Jenkins CI: http://ci.msgpack.org/job/java-jre5/
+
+
+Release 0.5.1 - 2010/12/14
+  BUG FIXES
+    Fixes cast error on GenericArrayType
+
+    Throws MessagePackException instead of NullPointerException if target is null
+    on pack method.
+
+
+Release 0.5.0 - 2010/12/09
+  NEW FEATURES
+    Dynamic template builder is rewritten. New ReflectionTemplateBuilder
+    supports DalvikVM.
+
+    Some optimization for dynamic code generator.
+
+    @MessagePackMessage accepts default filed option.
+    Added new field annotations: @Ignore, @Requred and @Index.
+
+    Supported pack/unpack/convertion of arrays including multidimensional arrays.
+
+    Added native pack/unpack routine of ByteBuffer. It will be zero-copy optimized
+    under a specific condition.
+
+
+Release 0.4.3 - 2010/11/10
+  NEW FEATURES
+    Added FieldList class and MessagePack.register(Class<T>, FieldList) method
+    to specify optional/nullable options on runtime without annotations.
+
+    Changed annotation name: @MessagePackNullable -> @Nullable
+    Changed annotation name: @MessagePackOptional -> @Optional
+
+    Supported pack/unpack/convertion of enums.
+
+    Added MessagePack.unpack(buffer, T to) and MessagePackObject.convert(T to)
+    methods. They can unpack/convert buffer/object into existing object and
+    eliminate re-allocation overhead.
+
+
+Release 0.4.2 - 2010/11/09
+  NEW FEATURES
+    Added MessagePackNullable annotation and Tempalte.tNullable(Template)
+    method.

+
+
+Release 0.4.0 - 2010/10/25
+  NEW FEATURES
+    Added MessagePackObject class and org.msgpack.object package that
+    represent unpacked (=dynamically typed) objects.
+    Unpacker.unpack method returns MessagePackObject instead of Object.
+
+    Added Templates class and org.msgpack.template package that provide
+    type conversion feature.
+
+    User-defined classes annotated with MessagePackMessage can be
+    pack/unpack/converted.
+
+    User-defined classes registered with MessagePack.register(Class) can be
+    pack/unpack/converted.
+
+    Added dynamic code generation feature for user-defined classes.
+
+    Added MessagePackOptional annotation.
+
+    Added MessagePack class that implements typical useful methods.
