> DLL dependencies for extension modules and DLLs loaded with ctypes https://docs.python.org/3/library/ctypes.html#module-ctypes on Windows are now resolved more securely. Only the system paths, the directory containing the DLL or PYD file, and directories added with add_dll_directory() https://docs.python.org/3/library/os.html#os.add_dll_directory are searched for load-time dependencies. Specifically, PATH and the current working directory are no longer used, and modifications to these will no longer have any effect on normal DLL resolution.
