 ### `$el` is now always the current element
 
-`$el` now always represents the element that an expression was executed on, not the root element of the component. This will replace most usages of `x-ref` and in the cases where you still want to access the root of a component, you can do so using `x-ref`. For example:

-For a smoother upgrade experience, you can optionally replace all instances of `$el` with a custom magic called `$root`, then add the following code to your site to mimic the behavior:
-
-```alpine
-<script>
-    document.addEventListener('alpine:init', () => {
-        Alpine.magic('root', el => {
-            let closestRootEl = (node) => {
