+- Support `libraryItems` argument in `initialData.libraryItems` and `updateScene({ libraryItems })` to be a Promise resolving to `LibraryItems`, and support functional update of `libraryItems` in [`updateScene({ libraryItems })`](https://github.com/excalidraw/excalidraw/blob/master/src/packages/excalidraw/README.md#updateScene). [#5101](https://github.com/excalidraw/excalidraw/pull/5101).
+- Expose util [`mergeLibraryItems`](https://github.com/excalidraw/excalidraw/blob/master/src/packages/excalidraw/README.md#mergeLibraryItems) [#5101](https://github.com/excalidraw/excalidraw/pull/5101).
