 ## Breaking Changes
 
+### v2.0.0
+- Internal structure of the editor directory has changed. When calling shadcn add, you will need to manually delete old files in /ui-builder and /lib/ui-builder directories.
+- Many components have been refactored to support drag and drop functionality and the new canvas.
+
 ### v1.0.0
 - Removed _page_ layer type in favor of using any component type (like `div`, `main`, or custom containers) as the root page layer. This enhances flexibility, enabling use cases like building react-email templates directly. You should migrate any layers stored in the database to use a standard component type as the root. The [migrateV2ToV3](lib/ui-builder/store/layer-utils.ts) function in `layer-utils.ts` can assist with this migration.
 - The `componentRegistry` is now passed as a prop to the `UIBuilder` component instead of being defined in a standalone file.
