 # mini-css-extract-plugin-contenthash
 
+## **Update:**
+
+This has been fixed in [#284](https://github.com/webpack-contrib/mini-css-extract-plugin/pull/284) and it's available in [v.0.4.4](https://github.com/webpack-contrib/mini-css-extract-plugin/releases/tag/v0.4.4) 🎉
+
+**NOTE:** This same issue happens with javascript in webpack as of this writing (v.4.20.2), but can be solved by adding both `NamedChunksPlugin` and `HashedModuleIdsPlugin`.
+
+Happy Building!
