 `msgpack::type::nil` is replaced with `msgpack::type::nil_t` to avoid conflict by [#408](https://github.com/msgpack/msgpack-c/pull/408). `nil` is defined by system on some environment. See #[368](https://github.com/msgpack/msgpack-c/pull/368) and [#406](https://github.com/msgpack/msgpack-c/pull/406). `msgpack::type::nil` is obsolete. You need to replace `msgpack::type::nil` with `msgpack::type::nil_t` in your codes. However, you might want to continue to use nil. If `MSGPACK_USE_LEGACY_NIL` is defined, `msgpack::type::nil` is defined as the typedef of `msgpack::type::nil_t`.

-`msgpack::object::convert(T*)` is removed to solve [#399](https://github.com/msgpack/msgpack-c/issues/399). You need to use `msgpack::object::convert(T&)`. If `MSGPACK_DISABLE_LEGACY_CONVERT` is NOT defined, `msgpack::object::convert(T*)` is removed. `msgpack::object::convert(T*)` is obsolete. It will be removed in the version 2.0.0. Please define `MSGPACK_DISABLE_LEGACY_CONVERT` to prepare the version 2.0.0 and update your code as follows:
-
-Replace

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

-```C++
-int i;
-obj.convert(i);
