Please consult [APIs of gregorian-calendar](https://github.com/yiminghe/gregorian-calendar) and [APIs of moment](http://momentjs.com/docs/), and update your code accordingly. Because the return value of `JSON.stringy(date: moment)` will lost time zone, we should use `.format` to convert date to string first, see related issue [#3082](https://github.com/ant-design/ant-design/issues/3082) for details:

+* For the value of time-related components becomes an instance of `moment`, you should replace `type='date'` with `type='object'` in form validation.
 * The `format` of time-related components is changed from [gregorian-calendar-format](https://github.com/yiminghe/gregorian-calendar-format#api) to [moment  format](http://momentjs.com/docs/#/parsing/string-format/) now, for instance the format `yyyy-MM-dd` should change to `YYYY-MM-DD`.
 * `linkRender` and `nameRender` of Breadcrumb are removed, please use `itemRender`.
 * `onClose` and `onOpen` of Menu are removed, please use `onOpenChange`. As being totally different, please check [this demo](http://beta.ant.design/components/menu/#components-menu-demo-sider-current) first.

-* 时间类组件的 `onChange` 和 `onPanelChange` 及其他回调函数中为 `Date/GregorianCalendar` 类型的参数，均修改为 moment 类型，两者 API 有所不同，但功能基本一致，请对照 [moment 的 API 文档](http://momentjs.com/docs/) 和 [gregorian-calendar 的文档](https://github.com/yiminghe/gregorian-calendar) 进行修改。由于 `JSON.stringy(date: moment)` 返回的值会丢失时区设置，所以要先使用 `.format` 把日期转成字符串，相关 issue 见 [#3082](https://github.com/ant-design/ant-design/issues/3082)：
