3 - Encode, Decode, Marshal, and Unmarshal are changed to accept single argument. EncodeMulti and DecodeMulti are added as replacement.
4 - Added EncodeInt8/16/32/64 and EncodeUint8/16/32/64.
5 - Encoder changed to preserve type of numbers instead of chosing most compact encoding. The old behavior can be achieved with Encoder.UseCompactEncoding.
9 - `msgpack:",inline"` tag is restored to force inlining structs.
13 - Decoding extension types returns pointer to the value instead of the value. Fixes #153
17 - gopkg.in is not supported any more. Update import path to github.com/vmihailenco/msgpack.
18 - Msgpack maps are decoded into map[string]interface{} by default.
19 - EncodeSliceLen is removed in favor of EncodeArrayLen. DecodeSliceLen is removed in favor of DecodeArrayLen.
20 - Embedded structs are automatically inlined where possible.
21 - Time is encoded using extension as described in https://github.com/msgpack/msgpack/pull/209. Old format is supported as well.
22 - EncodeInt8/16/32/64 is replaced with EncodeInt. EncodeUint8/16/32/64 is replaced with EncodeUint. There should be no performance differences.
23 - DecodeInterface can now return int8/16/32 and uint8/16/32.
24 - PeekCode returns codes.Code instead of byte.
