+  NEW FEATURES
+  * Enum name transformation via `SerializationContext.EnumSerializationOptions.NameTransformer`.
+    Built in transformer is placed in `EnumTransoformers`.
+    Issue #184.
+  * Polymorphic attributes now supports type qualification. Issue #171.
+  * Runtime type polymorphism now supports name based type verification. This feature allows to prevent loading malicious or unknown types ibefore assembly loading.
+  * Asymmetric serializers. You can generate "pack only" serializer when you set SerializationContext.CompabilityOptions.AllowAsymmetricSerializer to true. #68.
+  * Built in serializer for System.Text.StringBuilder now supports UnpackTo.
+  * Add serialization to/from MessagePackObject as extension methods of MessagePackSerializer and MessagePackSerializer<T>. Issue #90
+  * Users of serializer code generator API can specify TextWriter to output. This may improve tooling chain.
+  * Users of serializer code generator API can suppress [DebuggerNonUserCode] attribute to enable debugger step in.
+  * SerializerRepository API now expose ContainsFor and GetRegisteredSerializers methods to investigate registered serializers.
+  * SerializationContext.DisablePrivilegedAccess for restricted environment like Silverlight to select between granting permission or relinquish non-public access.
+  * UWP build is now included.
+  * ByteArrayPacker/ByteArrayUnpacker. They are suitable for fixed pattern serialization/deserialization.
+  * Fast mode of unpacker which omits nested collection management. This option can be disabled with setting UnpackerOptions.ValidationLevel to ValidationLevel.Collection.
+
+  IMPROVEMENTS
+  * Byte array based serialization API now uses ByteArrayPacker/ByteArrayUnpacker, improves about 40% faster than Stream based.
+  * Deserialization now uses ValidationLevel.None, improves about 30% faster than validating one.
+  * Packer/Unpacker performance improvements about 10-20%. As a result, new byte array "fast" unpacker is about 3x faster than previous unpacker.
+
+  BUG FIXES
+  * Fix nuspec to prevent old NuGet clients which do not support .NET Standard TFMs. Issue #177.
+  * The generated code for the type which has Tuple typed member uses old PackHelper API.
+  * Fix struct deserialization. Issue #189. Thank you @samcragg!
+  * Fix asynchronous packing is not be emitted correctly. Issue #201
+  * Fix SerializerCodeGenerator does not handle collections correctly for IsRecursive = true. Issue #203
+  * Fix extra field causes IndexOutOfBoundException when reflection based serializers are used. Issue #199
+  * Fix some built-in serializers throws InvalidOperationException instead of SerializationException for type errors. Issue #204
+  * Fix a combination of readonly members and collection members incorrect code generation when the type also have deserialization constructor. Issue #207.
+  * Fix built-in collection serializers such as List<T> serializer causes SecurityException when the program run in restricted environment like Silverlight. Issue #205.
+  * Fix null items of complex type in List<T> or Dictionary<TKey, TValue> will not be deserialized as null. Issue #211. (from 0.8.1)
+  * Fix types which implement IPackable and IUnpackable but do not have any members cannot be serialized. Issue #202
+  * Fix Windows Native build error. Issue #206.
+  * Fix constructor deserialization fails if the constructor parameters order is not lexical. Issue #233
+  * Fix asynchronous multi dimensional array deserialization corruption.
+  * Fix enum serialization throws NullReferenceException in Unity. Issue #215.
+  * Fix MessagePackSerializer.Capability does not work correctly in Unity.
