Zfast miner not working with any pool excluding miningpoolhub!
With new megaminer-master, zfast miner starts normally first time when it connect to miningpoolhub.
After that if other pool have best profit for zcoin (maybe ahashpool,maybe nicehash), zfast miner starts two times and after that zcoin is not shown on sorting table.
And profit calculation works only for first string.
Some miners are outdated  (excavator, z-enemy etc).
When we can see new release of megaminer?
