 ## 3.0.0 - 2018-04-17
 
-* Added: `cache` options (i.e. persistent cache), by default is `false` (because it is good practice to disable `cache` by default).
-* Changed: `imagemin-loader` now dynamically added in loaders list as `pre` loader (i.e. no need setup `imagemin-loader` in `webpack.config.js`).
-* Changed: use `webpack` errors and warnings `api`.
-* Changed: `imagemin` plugins for `loader` should be placed in `imageminOptions` options (look example in `README.md`).
-* Chore: refactor all plugin code (all source code now in `src` directory).
-* Deleted: `excludeChunksAssets` options (use `loader` options for plugin instead).
-* Fixed: use `maxConcurrency`, use `os.cpus().length - 1` for multi core systems and `1` for single core system.
-* Fixed: don't add same file paths in `manifest`.
