+- An unsuccessful completion (a <kbd>⮀ Tab</kbd> press that doesn't change the
+  command line) no longer causes highlighting to be lost.  Visual feedback can
+  alternatively be achieved by setting the `format` zstyle under the `warnings`
+  tag, for example,
+
+        zstyle ':completion:*:warnings' format '%F{red}No matches%f'
+
+    Refer to the [description of the `format` style in `zshcompsys(1)`]
+    [zshcompsys-Standard-Styles].
