+* The :c:type:`PyCompilerFlags` structure gets a new *cf_feature_version*
+ field. It should be initialized to ``PY_MINOR_VERSION``. The field is ignored

* The :c:func:`PyEval_ReInitThreads` function has been removed from the C API.
It should not be called explicitly: use :c:func:`PyOS_AfterFork_Child`
instead.
