New added property can't deserialized.

pulblic class SzTEST { public SzTEST() { }

// File version 1.0
[MessagePackMember(1)]
public string A { get; set; }

// File version 1.0
[MessagePackMember(2)]
public string B { get; set; }

// File version 1.0
[MessagePackMember(3)]
public string C { get; set; }

// File version 1.1
[MessagePackMember(4)]
public string D { get; set; }  // <- This property added on version 1.1

}

This is simple scenario for example. Suppose If I'm used SzTEST serialized and save as file. As time goes, a new requirement is occurred. So, adding a new property D for user request. But D can't deserialized on file version 1.0 and throws exception. ('Cannot deserialize member 'System.String D' of type SzTest') How I resolve it? I know IUnpackable interface implements is an alternative solution. But my real scenario has an very complex objects and fields to resolve it.

Sorry for delay.

It is not expected behavior at least in the latest version, and I cannot reproduce the problem. Could you put the code to reproduce, actual file which contains serialized binaries, and stacktrace of the error?

I'm used in version 0.6.0. I'm upgrade to version 0.8.1. It's works well. :) Thank you for your answer.
