# 2016-01-22 version 1.4.0

## << recommended changes >>

  * Define [MSGPACK_DISABLE_LEGACY_NIL](https://github.com/msgpack/msgpack-c/wiki/v1_1_cpp_configure#msgpack_disable_legacy_nil-since-140), then `msgpack::type::nil` is replaced by with `msgpack::type::nil_t` (#408, #411, #412).
    Replace `msgpack::type::nil` with `msgpack::type::nil_t` in client codes.
    `msgpack::type::nil` will be removed on the version 2.0.0.
  * Define [MSGPACK_DISABLE_LEGACY_CONVERT](https://github.com/msgpack/msgpack-c/wiki/v1_1_cpp_configure#msgpack_disable_legacy_convert-since-140), then `msgpack::object::convert(T*)` is removed (#410).
    Replace calling `msgpack::bojectconvert(T*)` with `msgpack::bojectconvert(T&)` in client codes as follows:

    ```C++
     int i;
     obj.convert(&i); // before
     ```

    ```C++
     int i;
     obj.convert(i);  // after
     ```

    `msgpack::object::convert(T*)` will be removed on the version 2.0.0.

Define the macros above as follows when you compile C++ codes that use msgpack-c:

```
g++ -Ipath_to_msgpack/include -DMSGPACK_DISABLE_LEGACY_NIL -DMSGPACK_DISABLE_LEGACY_CONVERT your_code.cpp

```

You can compile existing codes without defining macros above but I recommend defining them and updating your codes to fix the issues #408, #411, #412, #399, and #410. It is also a good preparation for the version 2.0.0.

## << breaking changes >>

    care about include order. Migration guide from 1.0.x to 1.1.0 has
