I am pleased to announce the first release of lua-MessagePack. MessagePack (http://msgpack.org/) is an efficient binary serialization format. lua-MessagePack is not the first implementation of MessagePack. It's a pure Lua implementation, without dependency. And it's really fast with LuaJIT. The homepage is at http://fperrad.github.com/lua-MessagePack/ and the sources are hosted at http://github.com/fperrad/lua-MessagePack/ All feedback welcome. Thanks.
