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`.
