Sass 3.4.11 发布，改进内容包括： Parent selectors used both outside and inside a pseudo selector (e.g. &:not(&--foo)) now compile correctly. Interpolation in a multiline indented-syntax selector is no longer omitted. Add a stack trace to the unquote() deprecation warning. When converting a space-separated list with sass-convert, add parentheses when they make it easier to read even if they aren't strictly required. 同时该版本废弃了： Compiling directories on the command line without using either--watch or --update is deprecated. This only worked inconsistently before. 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。 Sass 3.4.11 发布，CSS 框架下载地址
