+#### Manager API expandAll and collapseAll methods
+
+The `collapseAll` and `expandAll` APIs (possibly used by addons) are now removed. Please emit events for these actions instead:
+
+```ts
+import { STORIES_COLLAPSE_ALL, STORIES_EXPAND_ALL } from '@storybook/core-events';
+import { useStorybookApi } from '@storybook/manager-api';
+
+const api = useStorybookApi()
+api.collapseAll() // becomes api.emit(STORIES_COLLAPSE_ALL)
+api.expandAll() // becomes api.emit(STORIES_EXPAND_ALL)
+```
