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.
I updated the X10 with the new image, then reflashed the firmware to the GX10_V13 and the new algos still work (old firmware, new sgminer). What a machine the X10 is, 7 algo's and counting, still the best miner around for long term...
UPDATE My Bad, seems the firmware didn't take, tried again after editing update_fw.py and did flash but wouldn't find the devices,
