-## Unreleased
-
-## Excalidraw API
-
-### Breaking changes
-
- Renamed the `excalidrawAPI` prop to `onExcalidrawAPI`.
-
-### Features
-
- Added `onMount` and `onInitialize` props. `onMount` receives `{ excalidrawAPI, container }` once the editor root is mounted, and `onInitialize` fires once the initial scene has loaded.
-
-  ```tsx
-  <Excalidraw
-    onMount={({ excalidrawAPI, container }) => {
-      console.log(container);
-      excalidrawAPI.scrollToContent();
-    }}
-    onInitialize={(api) => {
-      api.refresh();
-    }}
-  />
-  ```
-
- Same events are also accessible imperatively through `api.onEvent(...)`.
-
-  ```tsx
-  <Excalidraw
-    onExcalidrawAPI={(api) => {
-      api.onEvent("editor:mount", ({ excalidrawAPI, container }) => {
-        excalidrawAPI.scrollToContent();
-        console.log(container);
-      });
-
-      api.onEvent("editor:initialize").then((readyApi) => {
-        readyApi.scrollToContent();
-      });
-    }}
-  />
-  ```
-
-  Note that in future releases, most, if not all, `excalidrawAPI.on*` subscriptions will be removed in favor of `excalidrawAPI.onEvent(name)`.
-
- Exported `ExcalidrawAPIProvider`, `useExcalidrawAPI`, and `useAppStateValue` from the package entrypoint. The imperative API also now exposes `onStateChange`.
-
-  ```tsx
-  <ExcalidrawAPIProvider>
-    <Excalidraw />
-    <Logger />
-  </ExcalidrawAPIProvider>;
-
-  function Logger() {
-    const api = useExcalidrawAPI();
-
-    useAppStateValue("viewModeEnabled", (viewModeEnabled) => {
-      console.log("view mode changed:", viewModeEnabled);
-    });
-
-    React.useEffect(() => {
-      if (api) {
-        console.log("editor instance id:", api.id);
-      }
-    }, [api]);
-
-    return null;
-  }
-  ```
-
- Added `onExport` so host apps can delay JSON export until async work completes. The handler receives the export data plus an `AbortSignal`, and may return a `Promise` or an async generator that yields progress updates for the built-in toast UI.
-
-  ```tsx
-  <Excalidraw
-    onExport={async function* (_type, { files }, { signal }) {
-      yield { type: "progress", message: "Waiting for images..." };
-
-      await waitForImagesToLoad(files, signal);
-
-      if (signal.aborted) {
-        return;
-      }
-
-      yield { type: "progress", message: "Export ready", progress: 1 };
-    }}
-  />
-  ```
