Sass 3.4.22 发布。 更新： Sass now runs without warnings when running ruby with code style warnings enabled. Sass no longer watches the current working directory unless it is on the load path or the files being compiled are in the current working directory. This was causing performance issues for users with large numbers of files in their project directory. Issue #1562, Issue #1966, Issue #2006. sass-convert now accepts a -q and --quiet option to disable ouput while it is running. Fixed a bug in sass-convert when recursively processing CSS files into Sass files which caused the process to crash without processing any files. Issue #1827 弃用——重要！ Support for Ruby 1.8.7 and 1.9.3 is deprecated. See this blog post for details. The current handling of CSS variables is deprecated. In order to support the CSS spec as fully as possible, no Sass-specific constructs other than #{} will be supported in CSS variable values. For forwards-compatibility, any SassScript being used in CSS variables must be moved into #{}. 详情：changelog 下载：3.4.22 Sass 3.4.22 发布，CSS 框架下载地址
