+Subject: [PATCH] python: get rid of a Python 3.9 warning
+
+As mentioned on:
+	https://cpython-ericholscher.readthedocs.io/en/sphinx-hoverxref/whatsnew/3.9.html
+
+The PyEval_InitThreads() and PyEval_ThreadsInitialized() functions are now
+deprecated and will be removed in Python 3.11. Calling PyEval_InitThreads()
+now does nothing. The GIL is initialized by Py_Initialize() since Python 3.7.
+
+So, let's not call it on Python 3.9, in order to avoid a
+warning noise.

+Subject: [PATCH] python: enum: fix build for Python 3.11
+
+Python 3.9 introduced Py_SET_SIZE function to set size instead of
+relying on Py_SIZE() as a macro [3.9].
+
+Python 3.10 started to encourage to use Py_SET_SIZE instead of
+assigning into return value of Py_SIZE [3.10].
+
+Python 3.11 flips the switch, turn Py_SIZE into a function [3.11],
+thus Py_SIZE(obj) will be a rvalue. We need to use Py_SET_SIZE
+to set size now.
