## Changelog

### 2.0.0-beta.1

*2017-10-20*

#### New features
- General
  - Added TypeScript typings
  - All existing icons are redesigned. Some new icons are added.
  - To help you migrate from Element 1.x, we added some console warnings against deprecated APIs. When you use a
  removed or renamed attribute or event in your project, you'll get a warning like this:
  ```
  [Element Migrating][ElSwitch][Attribute]: on-color is renamed to active-color.
  ```
  - Added a series of breakpoint-based utility classes that hide elements when the viewport size meets certain conditions
- Layout
  - Added a new breakpoint `xl` for viewport wider than 1920px
- Table
  - Added `span-method` attribute for merging cells
  - Added `clearSort` method to clear sorting programmatically
  - Added `clearFilter` method to clear filter programmatically
  - For expandable rows, when a row is expanded, a `.expanded` class will be added to its class list, so that you can customize its styles
- DatePicker
  - Added `unlink-panels` attribute to unlink the two date panels when selecting a date range
- Select
  - Added `reserve-keyword` attribute for reserving current search keyword after selecting an option

#### Fixes
- Table
  - Now `header-align` of TableColumn works properly
  - Fixed a bug that Table remains hiding when its parent element appears from `display: none`
  - Fixed Table expanding its width when its parent element has `display: flex`
  - Fixed a bug that fixed columns of a Table with `append` slot would disappear when data is dynamically fetched
  - Fixed `expand-row-keys` attribute not working with initial value
  - Fixed filter failing when `data` updates
  - Fixed a calculation error of fixed columns layout with grouped headers

#### Breaking changes
- Switch
  - Attributes starting with `on-*` will be parsed to events in JSX, making all `on-*` attributes of Switch not
able to work in JSX. So `on-*` attributes are renamed to `active-*`, and accordingly `off-*` attributes are renamed to `inactive-*`. This change affects the following attributes: `on-icon-class`, `off-icon-class`, `on-text`, `off-text`, `on-color`, `off-color`, `on-value`, `off-value`
- Table
  - `sort-method` now aligns with `Array.sort`. It should return a number instead of a boolean

### 2.0.0-alpha.3

*2017-10-16*

#### 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:
  ```JS
  import Vue from 'vue'
  import Element from 'element-ui'
  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'.

- Form
  - Form and Form-item now have a `size` attribute. Inner components will inherit this size if not specified on themselves, #7428
  - `validate` method will now return a promise if the callback is omitted, #7405

#### Fixes
- Fixed the console warning `Injection "elFormItem" not found` of some components

#### Breaking changes
- The params of DatePicker's `change` event is now the binding value itself. Its format is controlled by `value-format`
- Input's `change` event now behaves like the native input element, which triggers only on blur or pressing enter. If you need to respond to user input in real time, you can use `input` event.
