Sass 3.4.19 发布，此版本更新内容如下：
Sass numeric equality now better handles float-point errors. Any numbers that are within 1 / (10 ^ (precision + 1)) of each other are now considered equal.
Allow importing relative paths on standard input even when --stdin isn't explicitly passed.
Fix some busted edge cases with sass-convert and string interpolation.
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。
