So you can compile a Py_Limited_API for older CPythons just fine, you’ll just need to appropriately set the Py_Limited_API value. The reason for this is so CPython can *add* new functions to the stable ABI (but not remove or modify in an ABI incompatible way). So if you use a new to the ABI function, you’ll need a newer minimum.</div><div class="">
