+Pending removal in Python 3.17
+------------------------------
+
+* :mod:`typing`:
+
+  - Before Python 3.14, old-style unions were implemented using the private class
+    ``typing._UnionGenericAlias``. This class is no longer needed for the implementation,
+    but it has been retained for backward compatibility, with removal scheduled for Python
+    3.17. Users should use documented introspection helpers like :func:`typing.get_origin`
+    and :func:`typing.get_args` instead of relying on private implementation details.
+  - It is now possible to use :class:`typing.Union` itself in :func:`isinstance` checks.
+    For example, ``isinstance(int | str, typing.Union)`` will return ``True``; previously
+    this raised :exc:`TypeError`.
