+-------------------
+
+**Note:** Due to some internal changes to compass you may have issue with your sass cache. Run `compass clean` to clear your cache.
+
+* Added a new command: `compass clean` which removes any generated
+  css files and clears the sass cache.
+* Enable IE 10 support for flexible box with the -ms prefix.
+* A small change to how generated sprites are named for better
+  rails 3.1 compatibility.
+* Fixes for the compass --quiet mode.
+* It is now possible to generate cache buster urls that manipulate
+  the path of the image instead of the query string. This makes
