+-    Add `xmlns` attribute to icons downloaded with Iconify, to correctly render icons browser as an external file, in SVG editors, and in files explorers or text editors previews.
+It **may breaks your pipeline** if you assert on `ux_icon()` or `<twig:ux:icon>` output in your tests, and forgot [to lock your icons](https://symfony.com/bundles/ux-icons/current/index.html#locking-on-demand-icons).
+We recommend you to **lock** your icons **before** upgrading to UX Icons 2.24. We also suggest you to to **force-lock** your icons **after** upgrading to UX Icons 2.24, to add the attribute `xmlns` to your icons already downloaded from Iconify.
