+## 4.0.0
+* Breaking change: Dropped Node.js 4 support. Node.js 6.14.3 is the minimum supported version.
+* Could be a breaking change: Plugin won't sort inside some at-rule (mostly Sass specific directives). Read more about [ignored at-rules](https://github.com/hudochenkov/postcss-sorting#ignored-at-rules).
+* Added: `at-variables` keyword for `order`.
 
 ## 3.1.0
 * Added: `throw-validate-errors` option.
