 Previously !NoReverseMatch exceptions were silenced in the `{% url %}` tag.  This is very rarely useful, and usually just produced difficult to find bugs, and so was changed in [8211].  See #8031.

+== `intfield__in=['']` filter lookups no longer work ==
+
+Before [8131], `MyModel.objects.filter(intfield__in=[''])` would return an empty `QuerySet`, where `intfield` represents an `IntegerField` or similar on `MyModel`. For example, if you had been unpacking a comma-separated list of IDs into a lookup such as:
+{{{
+#!python
+authors = Author.objects.filter(id__in=author_ids.split(','))
+}}}
+then your lookup will fail if author_ids is an empty string, as of [8131].
