title: V4 to V5
---

This document will help you upgrade from antd `4.x` version to antd `5.x` version. If you are using `3.x` or older version, please refer to the previous [upgrade document](/docs/react/migration-v4) to 4.x.

## Upgrade preparation

1. Please upgrade to the latest version of 4.x first, and remove / modify related APIs according to the console warning message.

## Incompatible changes in v5

### Design specification

- Basic rounded corner adjustment, changed from `2px` to four layers of radius, which are `2px` `4px` `6px` and `8px`. For example, radius of default Button is modified from `2px` to `6px`.
- Primary color adjustment, changed from <div style="display: inline-block; width: 16px; height: 16px; border-radius: 4px; background: #1890ff; vertical-align: text-bottom;" /> `#1890ff` to <div style="display: inline-block; width: 16px; height: 16px; border-radius: 4px; background: #1677ff; vertical-align: text-bottom;" /> `#1677ff`.
- Global shadow optimization, adjusted from three layers of shadows to two layers, which are used in common components (Card .e.g) and popup components (Dropdown .e.g).
- Overall reduction in wireframe usage.

### Technology adjustment

- Remove less, adopt CSS-in-JS, for better support of dynamic themes. The bottom layer uses [@ant-design/cssinjs](https://github.com/ant-design/cssinjs) as a solution.
  - All less files are removed, and less variables are no longer exported.
  - Css files are no longer included in package. Since CSS-in-JS supports importing on demand, the original `antd/dist/antd.css` has also been abandoned. If you need to reset some basic styles, please import `antd/dist/reset.css`.
- Remove css variables and dynamic theme built on top of them.
- Remove `lib`, only provide `dist` and `es` in package.
- `babel-plugin-import` is no longer supported. CSS-in-JS itself has the ability to import on demand, and plugin support is no longer required. Umi users can remove related configurations.

```diff
// config/config.ts
export default {
  antd: {
-   import: true,
  },
};
```

### Compatibility

- DO NOT support IE browser anymore.

#### Component API adjustment

- The classname API of the component popup box is unified to `popupClassName`, and `dropdownClassName` and other similar APIs will be replaced.
  - AutoComplete
  - Cascader
  - Select
  - TreeSelect
  - TimePicker
  - DatePicker
  - Mentions

```diff
  import { Select } from 'antd';

  const App: React.FC = () => (
    <Select
-     dropdownClassName="my-select-popup"
+     popupClassName="my-select-popup"
    />
  );

  export default App;
```

- The controlled visible API of the component popup is unified to `open`, and `visible` and other similar APIs will be replaced.
  - Drawer `visible` changed to `open`.
  - Modal `visible` changed to `open`.
  - Dropdown `visible` changed to `open`.
  - Tooltip `visible` changed to `open`.
  - Tag `visible` is removed.
  - Slider `tooltip` related API converged to `tooltip` property.
  - Table `filterDropdownVisible` changed to `filterDropdownOpen`.

```diff
  import { Modal, Tag, Table, Slider } from 'antd';

  const App: React.FC = () => {
    const [visible, setVisible] = useState(true);

    return (
      <>
-       <Modal visible={visible}>content</Modal>
+       <Modal open={visible}>content</Modal>

-       <Tag visible={visible}>tag</Tag>
+       {visible && <Tag>tag</Tag>}

        <Table
          data={[]}
          columns={[
            {
              title: 'Name',
              dataIndex: 'name',
-             filterDropdownVisible: visible,
+             filterDropdownOpen: visible,
            }
          ]}
        />

-       <Slider tooltipVisible={visible} />
+       <Slider tooltip={{ open: visible }} />
      </>
    );
  }

  export default App;
```

- `getPopupContainer`: All `getPopupContainer` are guaranteed to return a unique div. This method will be called repeatedly under React 18 concurrent mode.
- Dropdown
  - The style of the wrapper element has been removed, please use the Space component.
  - `prefixCls` of Dropdown.Button changed to `dropdown`.
- Upload List structure changes.
- Notification
  - Static methods are no longer allowed to dynamically set `prefixCls` `maxCount` `top` `bottom` `getContainer` in `open`, Notification static methods will now have only one instance. If you need a different configuration, use `useNotification`.
  - `close` was renamed to `destroy` to be consistent with message.
- Drawer
  - `style` & `className` are migrated to Drawer Panel, the original properties are replaced by `rootClassName` and `rootStyle`.

#### Component refactoring and removal

- PageHeader and Comment components are removed in ant-design and moved to [pro-components](https://github.com/ant-design/pro-components) for maintenance. If you still need to use them, you can [import them from the compatible package](/docs/react/migration-v5#Import-the-obsolete-PageHeader-and-Comment-components-via-@ant-design/compatible-package).

```diff
- import { PageHeader, Comment, Input, Button } from 'antd';
+ import { PageHeader, Comment } from '@ant-design/compatible';
+ import '@ant-design/compatible/assets/index.css';
+ import { Input, Button } from 'antd';

  const App: React.FC = () => (
    <div>
      <PageHeader />
      <Comment />
    </div>
  );

  export default App;
```

- BackTop is deprecated in `5.0.0`, and is merged into FloatButton.

```diff
- import { BackTop } from 'antd';
+ import { FloatButton } from 'antd';

  const App: React.FC = () => (
    <div>
-     <BackTop />
+     <FloatButton.BackTop />
    </div>
  );

  export default App;
```
