+Subject: [PATCH] Use Py_ssize_t when parsing buffer length, fix #426 (#427)
+
+From python 3.9 documentation:
+
+> For all # variants of formats (s#, y#, etc.), the macro
+> PY_SSIZE_T_CLEAN must be defined before including Python.h. On Python
+> 3.9 and older, the type of the length argument is Py_ssize_t if the
+> PY_SSIZE_T_CLEAN macro is defined, or int otherwise.
+
+From python 3.8 changes:
+
+> Use of # variants of formats in parsing or building value (e.g.
+> PyArg_ParseTuple(), Py_BuildValue(), PyObject_CallFunction(), etc.)
+> without PY_SSIZE_T_CLEAN defined raises DeprecationWarning now. It
+> will be removed in 3.10 or 4.0. Read Parsing arguments and building
+> values for detail. (Contributed by Inada Naoki in bpo-36381.)
