The next version of Sass recently hit release candidate status, meaning it’ll be out in the wild any day now. There are some great changes coming in Sass 3.3, one of which should have developers extremely excited: sourcemaps.
Put plainly, sourcemaps are a way to map compiled code back to its native state. That may sound kind of odd, but sourcemaps will make every Sass-loving developer’s life a little bit better. Browsers that understand the generated map file will know where each and every line of code came from, down to the line number in the original Sass file, rather than the line number from the compiled CSS file.
Even in the pre-release state, sourcemaps are proving to be a big productivity boost for developers by cutting down debug time and making Sass code easier to optimize and improve. No need to wait for Sass 3.3 to be released officially: install the release candidate and try it out in your own projects!
