-# Migration Guide

-## Migrating to 1.6.0+
-
-### Additional Components are now split into separate packages
-
-If you're using Vue Flow at 1.6.0, please avoid using the `@vue-flow/additional-components` package, as it will *not*
-work with Vue Flow 1.6.0+.
-
-Instead, install the components from their respective packages.
-
-These packages include:
-
-- [`@vue-flow/background`](/guide/components/background)
-- [`@vue-flow/controls`](/guide/components/controls)
-- [`@vue-flow/minimap`](/guide/components/minimap)
-
-### Panel Component
-
-The `Panel` component has been moved into the `@vue-flow/core`package.
-If you're using it, please update your imports accordingly.
