+Notable changes in Python 3.7.1
+===============================
+
+Starting in 3.7.1, :c:func:`Py_Initialize` now consistently reads and respects
+all of the same environment settings as :c:func:`Py_Main` (in earlier Python
+versions, it respected an ill-defined subset of those environment variables,
+while in Python 3.7.0 it didn't read any of them due to :issue:`34247`). If
+this behavior is unwanted, set :c:data:`Py_IgnoreEnvironmentFlag` to 1 before
+calling :c:func:`Py_Initialize`.
