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
+* :c:func:`PyEval_EvalFrameEx`, :c:func:`PyObject_Repr(), and
+ :c:func:`PyObject_Str`, along with some other internal C APIs, now include
+ a debugging assertion that ensures they are not used in situations where
+ they may silently discard a currently active exception. 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.
+ because it has already been saved locally with :c:func:`PyErr_Fetch` or
+ is being deliberately replaced with a different exception), an explicit
+ :c:func:`PyErr_Clear` call will be needed to avoid triggering the
+ assertion when running against a version of Python that is compiled with
+ assertions enabled.
* :c:func:`PyErr_SetImportError` now sets :exc:`TypeError` when its **msg**
argument is not set. Previously only ``NULL`` was returned with no exception
