Not precisely sure what you mean, but nothing has changed from the Bitmain Firmware Page, up to this point. (time/date/etc)

Likely, IMHO, Bitmain will soon stop making firmware upgrades for this. In my case at 12c kwh, I can't see me running these

miners on Jan 1st, 2018!

(live and learn I guess)

This a weird world, where my original KNC Titan from Nov 6th, 2014 is still running and made today does $7.54 USD on 12c kwh at

1250 watts and 300mh.

Sheesh. 3 years and 1 month.

Yet this D3 is toaster city within 3-5 months at best.

Does not bode well, for my toaster purchases, from any ASIC manufacture in 2018!

oh well, I can't always pick winners

(on the other hand, the 2 D3's I have will make sturdy bookcase ends/doorstops/boat anchors/space heaters/shooting range targets/hamster hovels/etc)
