Baikal is now supplying a update for X10, including X11-Gost and NIST5 algo`s :-D
As usual, sgminer source code is not available from Baikal.
EDIT:
Oh, they also say more algo`s to come - we know what those are :-)
Can someone test something? From the new x10 Update, once you update, can you extract the new sgminer file. And then place it on a previous x10 version overwriting the sgminer only? Want to see if there were other changes needed or just a new correctly compiled sgminer file for it to work? Since there were no other firmware updates needed for the new algos to work.
