VERSION HISTORY


v9.7
---------------------------------------------------------------------

- Added ASM mode for RX460/560 cards, up to 30% speedup for second coin in dual mode.
- Improved ETH speed for some Nvidia cards.
- Improved speed in dual mode for Nvidia cards.
- reduced initialization time.
- a few minor bug fixes and improvements.
- EthMan: added ability to select several rigs.
- EthMan: several minor bug fixes and improvements.



v9.6
---------------------------------------------------------------------

- new GPU sorting method for AMD cards. Now GPUs are sorted by physical bus index (it matches AfterBurner list of GPUs). Also the list of temperatures/fans matches the list of GPUs automatically.
  Therefore "-di detect" and "-gmap" options are not necessary and not supported anymore.
  WARNING: be careful if you use use separate overclock/temperature settings for every card, due to new sorting method GPUs can get different indexes!
- added "-minspeed" option to restart miner/system if miner cannot reach specified speed.
- now watchdog monitors initialization steps too, e.g. it will restart miner even if miner hangs at GPUs initialization.
- added "-allcoins etc" option for ETC pools that require Username.Worker, in this mode devfee will be mined on some default ETC pools and DAG will not be recreated.
- added current DAG size info when "s" key is pressed.
- added 1 minute average speed for ETH when "s" key is pressed.
- fixed connection timeout issue in Linux version.
- fixed some issues related to remote management via TCP/IP.

- fixed epoch #0 support.
- a few minor bug fixes and improvements.
- EthMan: fixed issue with lost connection to some rigs.
- EthMan: added password for webserver.
- EthMan: added separate settings for every event.
- EthMan: added "retrigger" option for lost connection event.



v9.5
---------------------------------------------------------------------

- fixed issue with PASC, miner could check some nonces twice. Effective hashrate must be a bit higher now.
- improved SIA support for Nicehash, added "mining.extranonce.subscribe" and "client.reconnect" commands support. Effective hashrate must be a bit higher now.
- a few minor bug fixes and improvements.
- EthMan: added ability to enable/disable GPUs remotely (see API.txt for tech details).
- EthMan: added notification for too high fan speed.
- EthMan: several minor bug fixes and improvements.



v9.4
---------------------------------------------------------------------

- improved fans management for latest drivers and Polaris cards.
- added "-mpsw" option.
- added shares-per-GPU statistics when "s" key is pressed.

v9.3
---------------------------------------------------------------------

- improved dual mining speed stability in ASM mode.
- added "-altnum" option for alternative GPU indexing.
- a few minor bug fixes and improvements.



v9.2
---------------------------------------------------------------------

- improved mining speed stability.
- added changes in DCR mining protocol.
- fixed possible issue with rejected DCR shares on Nicehash pool.
- added pool selection in runtime ("e" and "d" keys).
- now if devfee mining fails for a long time, miner will not stop mining, it will turn on "-nofee" option temporarily with appropriate warnings, until successful devfee mining.
- some minor improvements.
- EthMan: added ReasonID parameter to .bat file which is executed when some rig has problems, check "sample.bat" for details.



v9.1
---------------------------------------------------------------------

- added assembler kernels for ETH+SIA and ETH+PASCAL modes (major speedup for SIA and PASCAL).
- added alternative assembler kernels for Tonga and Polaris cards for ETH-only mode. Use them if you get best speed at "-dcri 1" (i.e. you cannot find speed peak), use "-asm 2" option to enable this mode.
- a few minor bug fixes and improvements.



v9.0
---------------------------------------------------------------------

- added "-asm" option (AMD cards only) which enables assembler GPU kernels. In this mode some tuning is required even in ETH-only mode, use "-dcri" option or or "+/-" keys in runtime to set best speed.
    Currently only ETH-only and ETH-DCR modes are supported in assembler. Use "-asm 0" if you don't want to use new assembler kernels.
    If ASM mode is enabled, miner must show "GPU #x: algorithm ASM" at startup.
- improved ETH mining speed in ASM mode for some cards, also a bit reduced power usage for some cards (fine-tuning is required via "-dcri" or "+/-" keys in runtime). 
    NOTE 1: if GPU throttles, best "-dcri" value is different.
    NOTE 2: speed peak can be rather short, so change "-dcri" value slowly.
- dramatically increased DCR mining speed in assembler mode (up to 70%). Be careful, power usage is higher too.
- added "-gmap" option.
- fixed DCR Nicehash support.
- added "FINE-TUNING" section to Readme file.
- A lot of minor improvements and bug fixes.
