-#### New features
-- General
-- Configure component sizes globally. Now when you import Element, you can add a global config object with a `size` prop to configure default sizes for all components. For fully import:

-Vue.use(Element, { size: 'small' })
-```
-For partial import:
-```JS
-import Vue from 'vue'
-import { Button } from 'element-ui'
-
-Vue.prototype.$ELEMENT = { size: 'small' }
-Vue.use(Button)
-```
-With the above config, the default size of all components that have `size` attribute will be 'small'.

-
-#### 新特性
-- 综合
-  - 新增 TypeScript 类型声明
-  - 重绘了全部图标，并新增了部分图标
-  - 为部分非兼容性更新增加控制台警告，方便迁移项目。当你在项目中使用了被移除或更名了的属性或事件时，控制台会出现一条警告，例如：
-  ```
-  [Element Migrating][ElSwitch][Attribute]: on-color is renamed to active-color.
-  ```

-
-#### 非兼容性更新

-  ```
-  当按需引入 Element 时：
-  ```JS
-  import Vue from 'vue'
-  import { Button } from 'element-ui'
-  Vue.prototype.$ELEMENT = { size: 'small' }
-  Vue.use(Button)
