First of all I am very proud to be a NEM hodler since the beginning. I had many doubts because of the slow progress but I have never sold big amounts. The doubt has gone away ( at least the most ) but I am still wondering why the development progress of the software is so slow. The current version is 0.6.87. And there was less action on the github repository compared to the value of this project. I found less information about a roadmap with dates ( or at least roughly release dates like QX 201X ). Any information that would eliminate my remaining doubts?
They don't do much or any of their work on GitHub. It's mainly via a private repository. Catapult is the big project and it'll come when it comes. It's predicted for later this year. I've seen some cryptic allusions to August but they're in no hurry.
