+Will be called when the client `metaInfo` updates/changes. Receives the following parameters:
+- `newInfo` (Object) - The new state of the `metaInfo` object.
+- `addedTags` ([HTMLElement]) - a list of elements that were added.
+- `removedTags` ([HTMLElement]) - a list of elements that were removed.
+
+`this` context is the component instance `changed` is defined on.

+```js

+  metaInfo: {
+    changed (newInfo, addedTags, removedTags) {
+      console.log('Meta info was updated!')
+    }
+  }
+}
+```
