## Technical
##
- Commandline: Throw an error if separator character given by the user with -p option is not exactly 1 byte
- Kernel Cache: Add kernel threads into hash computation which is later used in the kernel cache filename
- HIP Kernels: Got rid of hip/hip_runtime.h dependancy to enable more easy integration of the HIP backend on Windows
- SCRYPT Kernels: Add more optimized values for some new NV/AMD GPUs
