V1.8.1
- Fixed a bug that could crash miner if using CNV4 (R) algo
- Fixed a bug that crashed miner if doing fast algo switching from CNV4 to any algo
- Stales are not displayed anymore by default, added parameter --showstales which turns back on the display of stale shares
- Changed --maxnosharesent default value from 15 minutes to 30
- Logging is now disabled by default in the example start.bat
- Added parameter --preparedata, which could pontentially make a small speed increase on weak GPU's, but also could make it worse. All algos except webchain

+ If you are having ocassional crashes out of nowhere while mining the new V4 (R) algo, please update to version 1.8.1 as this issue is now (hopefully) fixed

+ The info miner displays and is called 'stale shares' is not displayed by default anymore, so if you miss it, and know what is it (it only displays the number of shares sent after a new job was received, it's not the real number of stale shares - that's something only the pool knows), then you can turn it back on by adding --showstales in start.bat

+ A new experimental (beta) parameter --preparedata added, and when enabled CPU will prepare some stuff for the GPU before it begins to work, so this *could* potentially lead to a small increase in hashrate on weaker, older GPU's. I tested on Vega56 and Rx58x series, and there was no gain, but i would like someone to test on weak cards that i don't have, older gcn1,2 series.

Please all of you having crashes on 1.7.9 and 1.8.0 on V4 algo , try out 1.8.1 as this issue should be fixed now.

Hi dear
i install version 1.8.1
After 8 to 9 hours, the temperature of my Gpu increases without reason.
Up to 80 ° C
I will have to re-run the Meining software
Again 8 to 9 hours later this happens
The problem is not the cooling system

3x sapphire orginal pack vega 56 upgrade bios to vega 64 samsung chip

Try to disable automatic temp configuration or try extra conf :

"target_temperature" : 70,
"shutdown_temperature" : 80,

Goodluck
