I want to point out that the author of that linked blog, Soatok, actually removed a response in the comments from an OMEMO developer which clarified some things (you can it read here), which personally I think was rather odd/bad faith of them to do. When asked about it, this was their response: “I’ll make an edit later about the protocol version thing, but I’m not interested in having questions answered. My entire horse in this race is for evangelists to f** off and leave me alone. That’s it. That’s all I want.” According to the OMEMO developer in his response, there’s nothing really wrong with OMEMO 0.3.0, as the dev considers it a stable standard that clients can safely implement, with newer versions basically being public beta releases toward a stable ‘OMEMO 2’ standard that can eventually replace 0.3.0.
