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.
