Sass 3.4.10 发布了，下载地址：https://github.com/sass/sass/archive/3.4.10.zip Sass 扩展了 CSS3，增加了规则、变量、混入、选择器、继承等等特性。Sass 生成良好格式化的 CSS 代码，易于组织和维护。 该版本改进记录： inspect() no longer adds extra parentheses to nested maps. Update the documentation of the random() function to accurate reflect its behavior. 废弃的内容—— 必读！ Passing a non-string value to the unquote() function didn't do anything useful and is now deprecated. In future, this function will follow its documentation and emit an error if a non-string value is passed. Defining a function named calc, element, expression, or url(or the former two with a vendor-style prefix) is now deprecated. These functions were already shadowed by CSS functions with special parsing rules, and so were impossible to use anyway. In the future, attempting to define these functions will throw an error.
