 # Kickoff changelog
 All latest changes are documented on our site at http://tmwagency.github.io/kickoff/
 
+## Version 4.1.0 - Libsass
+18/05/2015
+
+As [node-sass](https://github.com/sass/node-sass) has been updated to v2, we can now use [grunt-sass](https://github.com/sindresorhus/grunt-sass) with Kickoff. It is faster and removes the dependency on Ruby from Kickoff.
+
+## Version 4.0.4 - Media query bugfix
+18/02/2015
+
+Fixes a strange bug with our [media-query mixins](https://github.com/tmwagency/kickoff/blob/master/scss/mixins/_responsive.scss). Apparently `em`-based media-queries do not calculate correctly if the font-size differs from the user's default — usually 16px. At this point, we have hard-coded 16 into our media-query mixins until we can find a better solution.

 ## Version 4.0.3 - scss linting

 ### Features
 * Built in a mobile-first, responsive philosophy *(but can easily be used for fixed sites as well)*
-* Sass compilation uses [autoprefixer]() to dynamically add vendor prefixes so you don't even have to think about it. We still have many Sass mixins for many CSS3 features including gradients, REMs with fallbacks

 * Starter content styles, including clean typography, lists, tables, etc
 * Starter form element styles: stacked on small-screen to 2-column (if you choose) at the breakpoint of your choice
 * Grunt used extensively to ease common development bottlenecks
- * Sass compilation using [grunt-contrib-sass](https://github.com/gruntjs/grunt-contrib-sass) although [grunt-sass](https://github.com/sindresorhus/grunt-sass) can be used, but there are still some bugs; it is far quicker though..
+ * Sass compilation using [node-sass](https://github.com/sass/node-sass) ([grunt-sass](https://github.com/sindresorhus/grunt-sass))
  * Concatenation and minification of JS files with and [grunt-contrib-uglify](https://github.com/gruntjs/grunt-contrib-uglify)
  * Simple server using [grunt-contrib-connect](https://github.com/gruntjs/grunt-contrib-connect)
  * SVG Icon generation using [grunticon](https://github.com/filamentgroup/grunticon)
