CHANGELOG.md

 # Change Log
+
 All notable changes to this project will be documented in this file.
 This project adheres to [Semantic Versioning](http://semver.org/).
 
+## [3.0.0-rc.0] - 2020-09-21
+
+### BREAKING CHANGE
+
+- minimum supported `Node.js` version is `>= 10.13.0 || >= 12.13.0 || >= 14`
+- minimum supported `postcss` version is `^8.0.3`
+- `postcss` was moved to `peerDependencies`, you need to install `postcss` in your project before use the plugin
+
 ## [2.2.0] - 2020-03-19
+
 - added the `exportGlobals` option to export global classes and ids
 
 ## [2.1.1] - 2019-03-05
+
 ### Fixed
+
 - add additional space after the escape sequence (#17)
 
 ## [2.1.0] - 2019-03-05
+
 ### Fixed
+
 - handles properly selector with escaping characters (like: `.\31 a2b3c { color: red }`)
+
 ### Feature
+
 - `generateExportEntry` option (allow to setup key and value for `:export {}` rule)
