Hi, Our bundled copy of libffi has been removed from Python 3.7 by this change which should explain the rationale: https://bugs.python.org/issue27979
Not all Python changes need a PEP. For Windows builds, we provide prebuilt binaries of our dependencies: https://github.com/python/cpython-source-deps/blob/master/README.rst My notes on Python dependencies: https://pythondev.readthedocs.io/files.html > we support older Linux distributions that don't have libffi I'm curious, which old Linux distributions don't have libffi? Usually, libffi is preinstalled on Linux, only the development header files are required (a package with a name like "libffi-devel"). Can't you install libffi on these old distributions? IMHO libffi installation should not be the Python problem, bundling a library copy in Python is causing more issues compared to advantages.
