 ## Improvements
 ##
 
+- Compile ZLIB: Fixed makefile include paths in case USE_SYSTEM_ZLIB is used
 - Compile macOS: Fixed makefile target 'clean' to correctly remove *.dSYM folders
 - OpenCL Kernels: Added pure kernels for hash-mode 600 (BLAKE2b-512)
 - OpenCL Runtime: Reinterpret return code CL_DEVICE_NOT_FOUND from clGetDeviceIDs() as non-fatal
