Release Notes

Fixed a problem when reading malformed UTF-8 characters in packString. This problem happens only if you are using an older version of Java (e.g., Java 6 or 7)
Support complex-type keys in msgpack-jackson

Fixed a bug that causes IndexOutOfBoundsException when reading a variable length code at the buffer boundary.

Add PackerConfig.withStr8FormatSupport (default: true) for backward compatibility with earier versions of msgpack v0.6, which doesn't have STR8 type.
msgpack-jackson now supports @JsonFormat(shape=JsonFormat.Shape.ARRAY) to serialize POJOs in an array format. See also https://github.com/msgpack/msgpack-java/tree/develop/msgpack-jackson#serialization-format
Small performance optimization of packString when the String size is larger than 512 bytes.

Fix a bug (#348), which wrongly overwrites the buffer before reading numeric data at the buffer boundary

Add some missing asXXX methods in Value
ValueFactory.MapBuilder now preserves the original element order (by using LinkedHashMap)
Fix ExtensionType property

MessagePack.Packer/UnpackerConfig are now immuable and configurable with withXXX methods.
Add bufferSize configuration parameter
Allow setting null to ArrayBufferInput for advanced applications that require dedicated memory management.
Fix MessageBufferPacker.toXXX to properly flush the output
Modify ValueFactory methods to produce a copy of the input data. To omit the copy, use omitCopy flag.
Improve the performance of MessagePackParser by unpacking data without using org.msgpack.value.Value.

Split MessagePack.Config into MessagePack.Packer/UnpackerConfig
Changed MessageBuffer API
- It allows releasing the previously allocated buffers upon MessageBufferInput.next() call.
- MessageBufferOutput now can read data from external byte arrays
MessagePacker supports addPayload(byte[]) to feed the data from an external data source
- This saves the cost of copying large data to the internal message buffer
Performance improvement of packString
Add MessageBufferPacker for efficiently generating byte array(s) of message packed data
