 * **$core:** - Plugin option `enhanceDevServer` was removed.
   - **For 0.x users**, there is no any effect since we didn't expose API to modify it.
-  - **For 1.x users whose version of VuePress is lower than 1.0.0-alpha.33**, you should use `beforeDevServer`(e.g. [before](https://webpack.js.org/configuration/dev-server/#devserver-before) in `webpack-dev-server`) to replace `enhanceDevServer`, you can also use `afterDevServer`(e.g. [after](https://webpack.js.org/configuration/dev-server/#devserver-after) in `webpack-dev-server`) to execute custom middleware after all other middleware internally within the server.
