I am pleased to announce a new release of lua-MessagePack. MessagePack (http://msgpack.org/) is an efficient binary serialization format. This release handles the specification v5 of MessagePack. lua-MessagePack stays a pure Lua implementation, without dependency. The homepage is at http://fperrad.github.io/lua-MessagePack/ and the sources are hosted at http://github.com/fperrad/lua-MessagePack/ All feedback welcome. Thanks.
