So I recently tried updating cgminer on two of my windows machines from 3.12.0 to 3.12.3 that are connected to multiple hashfast babyjets, and whenever I try running 3.12.3 cgminer just crashes on startup, yet 3.12.0 works...
I strongly advise people wait till they have new firmware as the new cgminer code is optimised around it and vice versa.
Sorry keeping up with everything is hard sometimes.
When's the new firmware being released?
