新闻 Less CSS 2.1.0 发布，CSS 预处理器 下载

Less CSS 2.1.0 发布了，改进内容包括：

• 
  Fixed isSync option, it was using sync file operations but promises are guaranteed to call back async. We now support promises as a feature rather than the 1st class way of doing things.
  
  
• 
  Browser code is now synchronous again, like in v1, meaning it blocks the site until less is compiled
  
  
• 
  Some fixes for variable imports which affected filemanagers when synchronous
  
  
• 
  Fixed lessc makefile dependencies option
  
  
• 
  output now reports back a imports field with an array of imported files
  
  
• 
  relative path test for drive names (so windows only) is now case insensitive
  
  
• 
  Fix for IE7 - use getChar instead of indexing array
  
  
• 
  variables using !important now output !important, which bubbles up to affect the rule
  
  
• 
  livereload cache buster is now treated specially
  
  
• 
  upgrade dependencies
  

Less CSS 是一个使用广泛的 CSS 预处理器，通过简单的语法和变量对 CSS 进行扩展，可减少很多 CSS 的代码量。

LESS 将 CSS 赋予了动态语言的特性，如 变量， 继承， 运算， 函数. LESS 既可以在 客户端 上运行 (支持IE 6+, Webkit, Firefox)，也可一在服务端运行 (借助 Node.js).
