Latest upstream release: 1.3.0 Current version/release in Fedora 23 branch/rawhide: msgpack-0.5.9-4.fc23 msgpack has been split out into its own repository and renamed to msgpack-c. It also has been relicensed to the Boost 1.0 license. Release URL: https://github.com/msgpack/msgpack-c/releases/tag/cpp-1.3.0 Please upgrade msgpack (and preferably also rename it to msgpack-c).
Actually, it doesn't need to be renamed to msgpack-c, since the canonical name is still msgpack.
