May Update has been posted -
https://blog.xtrabytes.global/xtrabytes/xtrabytes-news/on-the-pulse-may-edition/ There is still no sign of CCR in the Discord however from the message on the Patent update it is clear that, far from being ready in April, it is no where near being ready.
To my mind accountability for the patent work rested with the person doing it - CCR. He has failed in this and taken 5 months to realize he is in over his head. With this admitted competence point in the latest update the team has advised CCR, who they have admitted doesn't have the competency, will continue doing the patent work. From all of this it appears the patents, and thus proof of actual code is very far away.
Separately they are launching a simulation of how the network will work for developers. I question the decision to waste time developing and writing a simulation, and can only conclude main-net or a functional test-net is far way.
It's not a great update, but at least it is an update.
