Release Notes

### [`v3.1.4`](https://github.com/webpack/webpack-dev-server/releases/v3.1.4) [Compare Source](https://github.com/webpack/webpack-dev-server/compare/v3.1.3...v3.1.4) - Update to webpack-dev-middleware 3.1.3, which should fix paths with a space not working on Windows (#1392) - Fix `logLevel` option `silent` not being accepted by schema validation (#1372) --- ### [`v3.1.3`](https://github.com/webpack/webpack-dev-server/releases/v3.1.3) [Compare Source](https://github.com/webpack/webpack-dev-server/compare/v3.1.2...v3.1.3) - Fix HMR causing a crash when trying to reload --- ### [`v3.1.2`](https://github.com/webpack/webpack-dev-server/releases/v3.1.2) [Compare Source](https://github.com/webpack/webpack-dev-server/compare/v3.1.1...v3.1.2) - Speed up incremental builds (#1362) - Update webpack-dev-middleware to 3.1.2 --- ### [`v3.1.1`](https://github.com/webpack/webpack-dev-server/releases/v3.1.1) [Compare Source](https://github.com/webpack/webpack-dev-server/compare/v3.1.0...v3.1.1) - Update to [webpack-dev-middleware v3](https://github.com/webpack/webpack-dev-middleware/releases/tag/v3.0.0), which removes the deprecation warnings from webpack. --- ### [`v3.1.0`](https://github.com/webpack/webpack-dev-server/releases/v3.1.0) [Compare Source](https://github.com/webpack/webpack-dev-server/compare/v3.0.0...v3.1.0) #### Updates - Fancy logging; `webpack-log` is now used for logging to the terminal (webpack-dev-middleware was already using this). - The `logLevel` option is added for more fine-grained control over the logging. #### Bugfixes - MultiCompiler was broken with webpack 4. - Fix deprecation warnings caused by webpack 4. Note that you will still see some deprecation warnings because webpack-dev-middleware has not been updated yet. --- ### [`v3.0.0`](https://github.com/webpack/webpack-dev-server/releases/v3.0.0) [Compare Source](https://github.com/webpack/webpack-dev-server/compare/v2.11.2...v3.0.0) #### Updates - **Breaking change:** webpack v4 is now supported. Older versions of webpack are **not** supported. - **Breaking change:** drops support for Node.js v4, going forward we only support v6+ (same as webpack). - webpack-dev-middleware updated to v2 ([see changes](https://github.com/webpack/webpack-dev-middleware/releases)). #### Bugfixes - After starting webpack-dev-server with an error in your code, it would not reload the page after fixing that error (#1317). - DynamicEntryPlugin is now supported correctly (#1319). Huge thanks to all the contributors! Please note that [webpack-serve](https://github.com/webpack-contrib/webpack-serve) will eventually be the successor of webpack-dev-server. The core features already work so if you're brave enough give it a try! ---
