Looks like the dev is back and had put the project on hold.

Version 1.0.0 has no connection to the network!!!

The version that has connection is 0.15.2 which was cancelled by the dev since it was hijacked by an asic miner.
Those of you who are mining and keeping v.0.15.2 alive, please stop! It was killed off and should have been shut down.
The 1.0.0 was introduced on Friday 9th February.

In addition I think if I recall things right, 0.15 & 1.0.0 are running different algorithm.

We should be using v.1.0.0 or we can hope for the dev to step up and clear some stuff
