Less.js 2.5.0 发布，此版本主要更新信息如下：
supports the scoped @plugin directive to load function plugins
All directives are bubbled (e.g. supports), not just media
Performance improvements to the parser - should help non-chrome browsers with very large less files to be alot quicker.
the image size function respects include paths like other file functions
colour functions take a relative argument that applies percentages relatively instead of absolutely
include paths now allows : as a separator on windows (recognising and not splitting drive names by the backslash)
@import (css) does not pull the directive above comments
Fix for import statements without quotes sometimes causing issues
replace supports dimensions and colours
the browser field is set in the package.json for use with browserify
another fix to support paths being passed as a string instead of an array
detached rulesets can be used as default arguments
Fix alot of false warnings about extends
errors written to stderr more consistently
consistently keep units if strict units is off
Better support for comments in function all arguments
