 ### Features
 
+- `props.initialData` can now be a function that returns `ExcalidrawInitialDataState` or `Promise<ExcalidrawInitialDataState>`. [#8107](https://github.com/excalidraw/excalidraw/pull/8135)
+
 - Added support for multiplayer undo/redo, by calculating invertible increments and storing them inside the local-only undo/redo stacks. [#7348](https://github.com/excalidraw/excalidraw/pull/7348)
 
 - `MainMenu.DefaultItems.ToggleTheme` now supports `onSelect(theme: string)` callback, and optionally `allowSystemTheme: boolean` alongside `theme: string` to indicate you want to allow users to set to system theme (you need to handle this yourself). [#7853](https://github.com/excalidraw/excalidraw/pull/7853)
