+ * [BC BREAK] The Vue "build" was changed from `vue.esm.js` (full build) to
+   `vue.runtime.esm.js` (runtime build). With the runtime build, there are
+   two things that you cannot do:
+   
+   A) You cannot pass a string to `template`:
+   
+   ```js
+   new Vue({
+     template: '<div>{{ hi }}</div>'
+   })
+   ```
+   
+   B) You cannot mount to a DOM element and use its HTML as your template:
+
+   ```js
+    new Vue({
+      el: '#app', // where <div id="app"> contains your Vue template
+    });
+   ```
+
+    If you need this behavior, call `Encore.addAliases({ vue$: 'vue/dist/vue.esm.js' });`
