The PoWs They Are a-Changin'

Config files from 2.2.0 are NOT compatible. Please use a new folder for the miner or remove all old config files.

Changelog:

• AMD backend
  • Add compiler cache (speedup startup time) #1131
  • Add new - memory pattern (new tweak option) #1109
  • Add Mesa OpenCl support #1101
  • Reduce register usage #1080
  • Fix AEON auto suggestion #1030
• NVIDIA back-end
  • Increase Volta hashrate #1014
  • Reduce startup time #1121
  • Reduce memory foot print #950
• Other
  • UAC prompt will be displayed only when it is needed now.
  • Support for Monero POW change #1200
  • Support for Sumokoin POW change #1200
  • Add command line option --benchmark BLOCKVERSION #1200
  • Native support for different cryptonight forks #1200
  • Support for pool-generated configs (see above)
  • Slightly less paranoid TLS sercurity settings

Pools can now provide the pool configuration

We moved the pools configuration and crypto currency selection into an own config file with the default name pools.txt.
This will allow that pools can create an easy web interface where the user can insert the crypto address
to generate a config file for the users where all fall-back servers are added.
This will simplify the pool configuration for new users.

Monero PoW change

Please use monero7 for full support of the new Monero PoW change. The miner will switch auto-magically as the fork happens.

Sumokoin PoW change

Xmr-stak is supporting the upcoming PoW for Sumokoin. The fork date is currently not defined therefore all sumokoin miner should select the currency cryptonight until the fork height is announced.
The reason is that the new POW will use 4MiB memory per hash.
If sumokoin is directly selected the miner will be slower than with the selection cryptonight but will support auto switching.

Please note, that due to short notice, Sumokoin PoW support is provisional. We will update the commuinity if something is broken.

Necessary prerequisites

If the application does not start properly, please make sure that Visual Studio libraries are installed.
You can download them from https://go.microsoft.com/fwlink/?LinkId=746572

The miner is fully open source (GPLv3). This means each improvement can be reused by the community and you have always the possibility to verify the source code.

We would like say thank you to the community for the feedback and the contribution to the code.
