v2.30
+ major performance improvements for BeamHashIII (up to +2-3% dependent on GPU)
+ added AMD solvers for Ethash and Etchash
+ significantly reduced stale shares percentage on Ethash algorithm, it will improve hashrate on pool side
+ support Etchash algorithm (Ethereum classic algorithm after hardfork), use --algo etchash, miner auto switch to HF algorithm on epoch 390. Also you can use --algo etchash_test for testing Etchash on test network (HF epoch is 82)
+ reduced memory usage for Cortex 8GB solver (about 50MB)
Version 2.27, 2.29 and 2.30 have problem (ethereum mine): All devfee mining pools are unavailable
Version 2.28 good, no errors.
Please fix this error
