++-   Escape template name before formatting it into error messages, to avoid
++    issues with names that contain f-string syntax.
++    :issue:`1792`, :ghsa:`gmj6-6f8f-6699`
+ -   The ``xmlattr`` filter does not allow keys with ``/`` solidus, ``>``
+     greater-than sign, or ``=`` equals sign, in addition to disallowing spaces.
+     Regardless of any validation done by Jinja, user input should never be used
