Changes in the C API
--------------------
* :c:func:`PyObject_Str` now includes a debug assertion that ensures it will
no longer silently discard currently active exceptions. In cases where
discarding the active exception is expected and desired (for example,
because it has already been saved locally with :c:func:`PyErr_Fetch`), an
explicit :c:func:`PyErr_Clear` call will be needed to avoid triggering the
assertion.
* :c:func:`PyErr_SetImportError` now sets :exc:`TypeError` when its **msg**
argument is not set. Previously only ``NULL`` was returned with no exception
set.
