We are using dotless v.1.3.1
for compiling LESS files to CSS. According to their documentation, they are aiming to keep their major version compatible to the matching major version of less.js, so I think you should code against less.js v.1.3.0.
Also, we have in mind that using third party library to compile LESS files would not scale very good over the time, so we are considering to use less.js
for compilation and give an opportunity to the user to choose the version to code for.
