 MessagePack is an efficient binary serialisation format that lets you
 exchange data among multiple languages like JSON. msgpack-c is a C and
 C++ implementation of MessagePack.
+
+Note: this is the lastest version of msgpack including both C and C++
+implementations. Later versions have separate implementations for these
+languages. This slackbuild is maintained for compatibility with
+some slackbuilds which require msgpack-c.
+
+If you want install a newer version (>=6.0.0) please refer to following
+packages:
+- msgpack-c-cpp for only C++ implementation
+- msgpack-c-c for only C implementation
+(both packages can coexist)
