 Since _Excalidraw_ doesn't support server side rendering, you should render the component once the host is `mounted`.
 
-The following workflow shows one way how to render Excalidraw on Next.js. We'll add more detailed and alternative Next.js examples, soon.
+Here are two ways on how you can render **Excalidraw** on **Next.js**.
+
+1. Importing Excalidraw once **client** is rendered.
 
 ```jsx showLineNumbers
 import { useState, useEffect } from "react";
 export default function App() {
   const [Excalidraw, setExcalidraw] = useState(null);
   useEffect(() => {
-    import("@excalidraw/excalidraw").then((comp) => setExcalidraw(comp.Excalidraw));
+    import("@excalidraw/excalidraw").then((comp) =>
+      setExcalidraw(comp.Excalidraw),
+    );
   }, []);
   return <>{Excalidraw && <Excalidraw />}</>;
 }
 ```
 
+Here is a working [demo](https://codesandbox.io/p/sandbox/excalidraw-with-next-5xb3d)
+
+2. Using **Next.js Dynamic** import.
+
+Since Excalidraw doesn't server side rendering so you can also use `dynamic import` to render by setting `ssr` to `false`. However one drawback is the `Refs` don't work with dynamic import in Next.js. We are working on overcoming this and have a better API.
+
+```jsx showLineNumbers
+import dynamic from "next/dynamic";
+const Excalidraw = dynamic(
+  async () => (await import("@excalidraw/excalidraw")).Excalidraw,
+  {
+    ssr: false,
+  },
+);
+export default function App() {
+  return <Excalidraw />;
+}
+```
+
+Here is a working [demo](https://codesandbox.io/p/sandbox/excalidraw-with-next-dynamic-k8yjq2).
+
 The `types` are available at `@excalidraw/excalidraw/types`, you can view [example for typescript](https://codesandbox.io/s/excalidraw-types-9h2dm)

-# Arrows
-
-An arrow can be a child of a frame only if it has no binding (either start or end) to any other element, regardless of whether the bound element is inside the frame or not.
-
-This ensures that when an arrow is bound to an element outside the frame, it's rendered and behaves correctly.
-
-Therefore, when an arrow (that's a child of a frame) gets bound to an element, it's automatically removed from the frame.
-
-Bound-arrow is duplicated alongside a frame only if the arrow start is bound to an element within that frame.

 ### Features
 
-- Add `selected` prop for `MainMenu.Item` and `MainMenu.ItemCustom` components to indicate active state. [7078](https://github.com/excalidraw/excalidraw/pull/7078)
+- Support `excalidrawAPI` prop for accessing the Excalidraw API [#7251](https://github.com/excalidraw/excalidraw/pull/7251).
+
+#### BREAKING CHANGE
+
+- The `Ref` support has been removed in v0.17.0 so if you are using refs, please update the integration to use the [`excalidrawAPI`](http://localhost:3003/docs/@excalidraw/excalidraw/api/props/excalidraw-api)
+
+- Additionally `ready` and `readyPromise` from the API have been discontinued. These APIs were found to be superfluous, and as part of the effort to streamline the APIs and maintain simplicity, they were removed in version v0.17.0.
+
+- Export [`getCommonBounds`](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/api/utils#getcommonbounds) helper from the package [#7247](https://github.com/excalidraw/excalidraw/pull/7247).
+
+- Support frames via programmatic API [#7205](https://github.com/excalidraw/excalidraw/pull/7205).
+
+- Export `elementsOverlappingBBox`, `isElementInsideBBox`, `elementPartiallyOverlapsWithOrContainsBBox` helpers for filtering/checking if elements within bounds. [#6727](https://github.com/excalidraw/excalidraw/pull/6727)
+
+- Regenerate ids by default when using transform api and also update bindings by 0.5px to avoid possible overlapping [#7195](https://github.com/excalidraw/excalidraw/pull/7195)
+
+- Add `selected` prop for `MainMenu.Item` and `MainMenu.ItemCustom` components to indicate active state. [#7078](https://github.com/excalidraw/excalidraw/pull/7078)
+
+#### BREAKING CHANGES
+
+- [`useDevice`](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/api/utils#usedevice) hook's return value was changed to differentiate between `editor` and `viewport` breakpoints. [#7243](https://github.com/excalidraw/excalidraw/pull/7243)
