+### Shorthand for `FieldPanel` and `InlinePanel`
+
+Plain strings can now be used in panel definitions as a substitute for `FieldPanel` and `InlinePanel`, avoiding the need to import these classes from `wagtail.admin.panels`:
+
+```python
+class MyPage(Page):
+    body = RichTextField()
+    content_panels = [
+        'body',
+    ]
+```

+This feature was developed by Matt Westcott.
