- Table now supports custom templates via [scoped slots](http://vuejs.org/v2/guide/components.html#Scoped-Slots); the good old `inline-template` is still compatible, but it's no longer recommended and is likely to be removed in the future
- Table now supports expandable rows
- DatePicker now supports specifying the first day of week
- TimeSelect now supports `maxTime`
- Autocomplete now supports `popper-class`
- To customize template of Tab-Pane, now you can use the `slot` named `label`
Fixes:
-`change` event of DatePicker incorrectly triggering multiple times, #2070
- Width shaking of tab-pane while initializing, #1883
Breaking changes:
- Only compatible with Vue 2.1.6 and beyond
- Parameters of Form validateField() methods are updated
- Alert's render-content attribute is removed, and now you can pass your custom template via default slot
- The box models of Input and Select are updated from `block` to `inline-block`
- The box model of Tabs is updated from `inline-block` to `block`, and Tab-Pane's `label-content` attribute is removed
- The dropdown of Autocomplete now inserts directly to `<body>`, not `<el-autocomplete>` any more
