PM 6.2c

• Using the newer AMD RX470/480/570/580 kernels even on older drivers (Windows driver 19.2.1, or newer; and Linux driver 19.10, or newer). If you want to revert to the older kernels on these drivers, use the new command line parameter -clabi 1
• Added a workaround for the SSL pools with self-signed or expired SSL certificate: you can use the new command-line parameter -weakssl (for the pool specified by -pool), or -weakssl2 (for the pool specified by -pool2), or the new WEAKSSL: 1 option for the pools in epools.txt.
Note that this option must be specified independently for each pool: if you use -weakssl on the command line (or in config.txt), it won't affect the pools specified in epools.txt. Instead you need to add WEAKSSL: 1 for each desired pool in epools.txt
• Fixed a crash with Nvidia cards on some older drivers (e.g. 460.79, and 460.89). If PhoenixMiner crashes or exits while showing Initializing NVML... try the new command line parameter -nvmalt
• Validated support for AMD Windows drivers 22.4.2
• Other small fixes

PM 6.1b

• Fixed an issue with expired SSL certificate that led to "certificate verify failed" errors when connecting to some pools (notably Ethermine) when using SSL connections
• Now the miner will send SSL SNI host name which may be needed by some pools for SSL certificate validation. To go back to the old behavior (no SNI host name), use the new command-line parameter -nosni
• Added support for latest AMD Windows drivers up to version 22.4.1
• Other small fixes

PM 6.0c

• Implemented partial unlocking of Nvidia LHR cards. By default they are detected automatically, and unlocked with the default unlock intensity (520). If you want to try higher (or lower) LHR unlock intensity, use the new -lhr command line parameter. For example -lhr 580 will try more aggressive unlocking than the default 520 unlock intensity. This parameter may (and should) be specified for each GPU separately as some GPUs can support higher unlocked speeds.
• If an Nvidia LHR card locks up because of high -lhr (the default 520 will work with most cards), the card will be unlocked again, and the -lhr value will be lowered if necessary
• Added support for new AMD Windows drivers up to driver version 22.2.3
• Multiple other small fixes and improvements

The updated list of known issues (driver incompatibilities, etc.) and workarounds:

• The new Nvidia 3050 and 3080 12GB cards have different kind of LHR lock, which is not supported yet.
• The latest AMD Linux drivers 21.50 are not supported; the AMD Linux drivers 21.40.2 aren't verified also - this will be added in the final release of 6.0 next week.
• AMD Linux driver 21.40.1 has a bug preventing proper setting of clocks and voltages on older cards (RX4x0/RX5x0/Vega/RadeonVII). Given that these drivers are also usually slower than the older drivers for these cards, we recommend using Linux drivers 20.30 for anything older than RX6000 series.
• If you are using Linux drivers 21.40.1 with Radeon VII cards, you need to add the option -fpwm 1 in order to have proper fan control.
• AMD Linux drivers 21.40.1 has finally removed the requirement of PCIe atomics but there are problems when you try to mix Polaris (RX4x0/5x0) cards and Vega or newer cards on the same rig.
• Some Nvidia cards will report a lot of stale shares under Windows 11. Using the same driver version under Windows 10 resolves the issue.

PM 5.9d

• Show the GPU vendor name in the list of GPUs to make it easier to identify the GPUs
• Added support for the latest AMD Linux drivers 21.40.1. There are some bugs in these drivers, particularly the clocks and voltages can't be set properly with older cards (RX4x0/RX5x0/Vega/RadeonVII)
• Validated support for the latest AMD Windows drivers up to 21.11.3
• Fixed issues with AMD RX6700XT cards with the latest AMD and Linux drivers
• Fixed issues with AMD Vega and Radeon VII cards on latest Windows and Linux drivers
• Fixed crash with very old Nvidia drivers (3xx.x)
• Fixed some pool connection issues
• Fixed issues with AMD RX6700XT with older drivers (regression in 5.9b, and 5.9c)
• Other fixes and small improvements
