Zilliqa - share denied
when dual mining ETH (on nanopool) + ZIL (on ezil.me), there's no rejection of ETH shares, but usually more than 50% of ZIL shares are denied. on ezil.me stat page, only valid shares are counted, but not the rejected ones (always zero). therefore I assume that rejection occurs locally on the rig / in nanominer.

Version 3.4.3 of the miner is available. Changelog:
Improved performance KawPow (Raven) and FiroPow (FIRO) on Nvidia GPUs (up to 3% depends on GPU model).

In order to process the update, specify  autoUpdate=true  in config and restart the miner.
