v11.3:
- removed devfee, miner is completely free now.
- added "-pow7" option to support Monero hardfork, use "-pow7 1" value to enable it.
- reduced CPU usage for systems with a lot of GPUs.
Does V7 use the similar amount of the core or memory?
Does it use similar power so that we can use the same setting (work size, GPU frequency) as the previous PoW algorithm?
