+## New Components
+
+You can explore our new playground at `docs.ohif.org/ui` to see the latest components and their properties. We haven't provided a migration guide yet because the old components are still available. Feel free to update your codebase, including custom extensions and UI, to use the new Button, Dropdown, Icons, and other new components from `@ohif/ui-next`. The old methods (importing from `@ohif/ui`) will continue to work for now. However, the new components have a slightly different API, and we plan to deprecate the old components in a future release, as we see the new ones as the future of OHIF.
