Semantic UI 2.0.0 发布，更新内容如下：

迁移指导

迁移不会太困难，只要注意以下这些重要改进：

Modal -如果你的 modal 有图片内容，那么你需要在父元素使用图片内容。因为 flex 规则要求父样式，previoustable-row 规则不要求。
Modal - Modal 现在只能在匹配禁用和启用选择器的按钮中关闭。任意按钮都要在匹配其中一个选择器的点击下才能隐藏 modal，或者 call$('.ui.modal').modal('hide') onclick。
网格 - 废弃页面网格，因为页面网格样式响应页面内容
下拉- 下拉功能现在会根据现有的可用屏幕空间来改变打开方向，可以强制打开方向({ direction: 'upward'})
表单验证 - 表单验证现在通过一个字段对象传递设置。
复选框 - 复选框 fireOnInit 现在默认是 false。
下拉功能 - 下拉项描述在默认主题中是浮动的，而且应该被包含在其他项内容的前面
表单 - 内联分组字段不再水平显示
输入 - 在图标输入中，除非是链接图标，已经移除了 pointer-events
弹出 - 弹出不再默认是唯一的。弹出一个的时候不需要再关闭其他可见的弹出
颜色 - 默认颜色调整，只会轻微的改变你的设计
Segment - Segment 不再默认包含 clearfix
Rail - Rail 现在使用 border-box 来代替 content-box
菜单 - 移除了分层菜单
Tab - onTabInit 和 onTabLoad 重命名为 onFirstLoad 和 onLoadrespectively
Button - 宽度变更使用 numbers 2 wide，移除了 3 wide，因为不兼容一些构建工具。请使用 two wide 或者 three wide 代替
Video - 未公开的视频模块重命名为 embed，行为是一样的，但是用户需要调整他们的 JavaScript 初始化为 $('.ui.embed').embed();
API - 当请求错误(504, 404 etc), aborted (page change or CORS) 或者 JSON 没有通过 successTestfunction 的时候，API onFailure 被称之为 in all failure conditions

新 UI 元素

Container - Containers are fixed width containers meant for holding page contents, and are a simpler alternative to ui page grid, view more examples in docs
Multiselect - New multiple dropdown types have been added. Many new dropdown improvements have been added including tagging/tokenizing features and loading data through API requests.
Embed - New embed component allows for responsive iframe embeds that maintain their aspect ratio. Embed can be used with YouTube or Vimeo videos, along with placeholder content to avoid loading third party libraries until a user chooses to interact with the video.

主要改进(务必要看！)

Site - 添加新的颜色：橄榄，紫色，棕色和灰色 Thanks @lemartialou
API - API can now be used with mocked responses, and custom AJAX requests.mockResponse has been added to resolve request with a prespecified JSON object, or a synchronous function callback.
API mockResponseAsync has been added for custom asynchronous requests. This allows you to specify a custom async callback to resolve an API request, helping with integration with libraries like Ember or Angular that may wrap AJAX requests.
API - API callbacks now have an onResponse callback that can adjust a servers response before it is parsed by other callbacks for success or failure conditions. Thanks@mnquintana
API - API now provides a local caching setting to avoid server roundtrips for identical urls by using cache: 'local'. This is not enabled by default. Local caching is useful for results that should return the same values across a single session, for example when querying an autocomplete.
Card - Cards now support multiple custom content blocks. Content blocks and images can now appear in any order.
Checkbox - Checkbox no longer require javascript to function.
Checkbox - Added support for indeterminate checkboxes, along with new stylings.
Checkbox - Now includes separate behaviors for triggering state changes without invoking callbacks set checked vs checked
Dropdown - Added remote API integration with dropdown, to allow search selection to query against a remote dataset.
Dimmer - Dimmers now have a blurring variation which apply a glass-like effect when dimmed
Dropdown - Dropdowns now automatically observe changes in menu and will update selector cache with new additions
Dropdowns - Added ability to add custom choices to all search selection dropdowns (multi/single) using allowAdditions: true setting. Search now displays error messages on no results in all cases.
Dropdown - Keyboard shortcuts have been added for selecting dropdown choices, for example "N" will scroll to "New York" in a state selection list, similar to native <select>behavior.
Dropdown - Added new dropdown variation scrolling dropdown and scrolling menu, this can be used to include a scrollable section inside a dropdown menu.
Dropdown - Dropdown will automatically animate upward if there is not enough space to appear below.
Dropdown - Using page up and page down keys will now scroll menus by a page at a time
Form - Forms now use flexbox for creating field groups. Inline fields now support (x) widesizing using flex
Grid - Grids now use flexbox, columns are now all equal height by default. New flexbox alignment types like stretch have been added for easier vertical alignment.
Multiple UI - Many components now use flexbox, which means previous confusing fixes likefont-size: 0; to remove white-space from inline block is no longer necessary. Removing this hack, now means any element can be a direct child of grid or menu.
Modal - Added new settings blurring and inverted which automatically set a modal's dimmer to either inverted or blurring.
Menu - Menu now uses flexbox. This allows menu items to match each others heights regardless of each items content size. right menu content should now follow other menu content instead of preceding it (no longer uses float).
Grid - Grids are now flexbox and equal height by default, the equal height variation can safely be removed
Popup - Popup has been rewritten to drastically improve performance, especially when testing multiple positions.
Transition - Fallback javascript animations have been removed from UI components like dropdown and popup to increase performance. This removes need for expensive pseudo selectors like :visible, :animated and :hidden and reduces filesize.
Form Validation - Form validation now uses a single settings object like other modules. Using (fields, settings) will continue to work but will produce a deprecation notifications inconsole
Form Validation - Form validation now supports many new validation rules, including some specifically for use with multiple select values.
Item - Items now uses flexbox for layout.
Message - icon message now uses flexbox for layout
Menu - vertical tabular menu, a vertical tab menu, has been added
Input - All input types use flexbox for layout
Segment - Segments now support complex nesting, many new rules for how segment groups should appear inside groups
Segment - New horizontal segment groups make laying out auto resizing text columns much easier.
Sidebar - iOS will now correctly report scrollTop values for document or body when using a sidebar. Chrome on iOS no longer has issues with fixed content not sticking immediately when using a sidebar.
Shapes - Shapes now correctly adjusts for margin on sides
Steps - Steps now use flexbox, fluid steps now center content inside each step
Steps - Steps no longer need item count and will automatically divide evenly
Transition - Transition code has been optimized to increase performance. 100% improvement on first animation, and 40% improvement on subsequent animations.
Visibility - Using .visibility({ type: 'fixed'}) will now automatically add a placeholder element which will swap places with an element when it is attached to the viewport. This should make fixed content drastically simpler.
Visibility - Visibility and sticky now use a more performant pub/sub pattern that will only attach a single event to context scroll.
Visibility - Added two new visibility callbacks onOnScreen and onOffScreen, which occur, most obviously when an element first appears in or out of a browser's viewport.

功能增强

Site - Added many new site variables, including the ability to control input size across all UIinputPadding, along with more border colors, accents, and colors.
