@ -42,6 +42,12 @@ Pass in your own callback to be called upon successful compilaton by node-sass.
Pass in your own callback to be called upon a sass error from node-sass. The callback has the form `callback(err)`, where err is the error string generated by libsass. Note: this *does* prevent an actual `gulpPluginError` object from being created.
## Source Maps
gulp-sass now generates *inline* source maps if you pass `sourceComments: map` as an option. Note that gulp-sass will *only* generate inline source maps, so passing `sourceMap: filepath` to node-sass won't actually do anything. Enjoy your source maps!
NB: For those wondering, inline source maps are stuck onto the end of the css file instead of being in a separate map file. In this case, the original source contents are included as well, so you don't have to make sure your scss files are servable.
#Imports and Partials
gulp-sass now automatically passes along the directory of every scss file it parses as an include path for node-sass. This means that as long as you specify your includes relative to path of your scss file, everything will just work.
