+
+### Mermaid is ESM only!
+
+We've dropped CJS support. So, you will have to update your import scripts as follows.
+
+```html
+<script type="module">
+  import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs';
+  mermaid.initialize({ startOnLoad: true });
+</script>
+```
+
+You can keep using v9 by adding the `@9` in the CDN URL.

+```diff
+- <script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.js"></script>
++ <script src="https://cdn.jsdelivr.net/npm/mermaid@9/dist/mermaid.js"></script>

+
+### mermaid.render is async and doesn't accept callbacks
+
+```js
+// < v10
+mermaid.render('id', 'graph TD;\nA-->B', (svg, bindFunctions) => {
+  element.innerHTML = svg;
+  if (bindFunctions) {
+    bindFunctions(element);
+  }
+});
+
+// Shorter syntax
+if (bindFunctions) {
+  bindFunctions(element);
+}
+// can be replaced with the `?.` shorthand
+bindFunctions?.(element);

+// or
+try {
+  await mermaid.parse(text);
+} catch (err) {
+  parseError(err);
+}

+
+### Init deprecated and InitThrowsErrors removed
+
+The config passed to `init` was not being used eariler.
+It will now be used.
+The `init` function is deprecated and will be removed in the next major release.
+init currently works as a wrapper to `initialize` and `run`.
+
+```js
+// < v10

 - Config has a lot of changes
 - globalReset resets to `defaultConfig` instead of current config. Use `reset` instead.
