+    - message: >+
+        The `.page-header-headings` CSS class now has a background colour
+        applied to the maintenance and secure layouts.
+
+
+        You may need to override this class in your maintenance and secure
+        layouts if both of the following are true:
+
+        * Your theme plugin inherits from `theme_boost` and uses this CSS class
+
+        * Your theme plugin applies a different styling for the page header for
+        the maintenance and secure layouts.
