-## Known issues
-
-- Outdated libsass in node-sass. This is a main cause of a bug with compiling Twitter Bootstrap SASS to CSS (see [this](https://github.com/andrew/node-sass/issues/233) thread and [this](https://github.com/dlmanning/gulp-sass/issues/1) for details). **Not a gulp-sass issue**! Temporarily using Ruby version (slower but stable).
-
 ## TODO
 
-- replace Ruby SASS compiler with NodeJS equivalent
 - add support for external sources in vendor files (http://*)
 - add source maps support for SASS & JS
 - add authorization service
