 ### Part of api from v3 not available in v4?
 
 AutoComplete is a Input component support auto complete tips which should not support `labelInValue` prop to modify dispaly value in input. In v3, AutoComplete realization can not handle case that user type match of both `value` & `label` are the same. v4 not longer support `label` as the value input.
+
+Besides, to unique API, `dataSource` replaced with `options`:
+
+#### v3
+
+```tsx
+dataSource = ['light', 'bamboo'];
+// or
+dataSource = [
+  { value: 'light', text: 'Light' },
+  { value: 'bamboo', text: 'Bamboo' },
+];
+```
+
+#### v4
+
+```tsx
+options = [
+  { value: 'light', label: 'Light' },
+  { value: 'bamboo', label: 'Bamboo' },
+];
+```

 ### v3 的部分属性为何在 v4 中没有了？
 
 AutoComplete 组件是一个支持自动提示的 Input 组件，因而其不具有 `labelInValue` 等影响 value 展示的属性。在 v3 版本，AutoComplete 实现存在输入值如果遇到 `value` 与 `label` 相同时无法映射的问题。 v4 中不再支持 `label` 为值的输入形态。
+
+此外为了统一 API，`dataSource` 改为 `options` 你可以如下转换：
+
+#### v3
+
+```tsx
+dataSource = ['light', 'bamboo'];
+// or
+dataSource = [
+  { value: 'light', text: 'Light' },
+  { value: 'bamboo', text: 'Bamboo' },
+];
+```
+
+#### v4
+
+```tsx
+options = [
+  { value: 'light', label: 'Light' },
+  { value: 'bamboo', label: 'Bamboo' },
+];
+```
