Great to hear another update from the darkcoin team!
Development on RC4 is nearing an end and we expect that well be firing up testnet in the coming week. Depending on what we find, testing and QA should take 2 to 4 weeks.
I'm all for taking the time needed to do it right, but, ugh. Does that mean no RC4 in late July as originally planned, then? Don't know how much more of this price slide I can stomach.
