Here are the changes for this release:

Fixed the issue with Nvidia RTX20x0 and 1660 cards not working with 4.2a
Fixed the problem with the watchdog timer when solo mining
Added support for Windows AMD drivers 19.3.2
Small bugfixes

Here are the changes from 4.1c to 4.2a:

Added support for dual mining Ethash and Blake2s on Nvidia GPUs
Added experimental support for ProgPOW mining of Bitcoin Interest (BCI). Note that the kernels are not optimized and only work on AMD. You must add -coin bci to the command line (or COIN: bci to your epools.txt file) in order to mine BCI.
Added support for EthereumStratum/2.0.0 protocol (use -proto 5 if the pool requires it).
AMD hardware control code was rewritten, now should be more stable and work on older cards too
Added command-line option -fcm to set the way fans are controlled (AMD/Windows only). The possible values are 0 (auto; the default behavior), 1 (use VBIOS/driver), 2 (force custom control of the fans regardless of VBIOS/drivers fan curves, etc). Use -fcm 2 if the fans are not controlled properly or at all
Added support for Radeon VII
Added support for AMD drivers up to 19.3.1
Added new command-line option -nvkernel to select the old (v1) or new (v2) CUDA kernels. The possible values are 0 (auto; the default), 1 (use the old v1 CUDA kernels from PhoenixMiner 3.5), 2 (use the new v2 kernels, which were introduced with PhoenixMiner 4.0). This was added because there were some complains that the new kernels are running slower on some Nvidia cards. Note that v1 CUDA kernels doesn't support dual mining.
Increased the maximum supported DAG epoch to 329. This should be fine for at least a year or so.
Added support for direct mining without DAG switching of Yocoin (YOC), Bitcoiin2Gen (B2G), Ethersocial (ESN), Atheios (ATH), and REOSC. See the -coin parameter in Readme.txt for more information.
Other small improvements and fixes.

Here is an example command-line for mining BCI (ProgPOW) - be sure to change YourBciWalletAddress with your actual BCI wallet address:

Code:

PhoenixMiner.exe -pool eu-1.pool.bci-server.com:3869 -wal YourBciWalletAddress.Rig1 -coin bci -proto 1
