This is an attempt to both be precise about what this defninition of a "v3 DFD" is, and also to encourage people to think about diagramming techniques themselves as something that, like code, can be specified and evolved over time, and labeled with a version. +Many people have presented various different ways to craft data flow diagrams over the years.
