Release Notes

webpack-contrib/copy-webpack-plugin

### [`v5.0.4`](https://togithub.com/webpack-contrib/copy-webpack-plugin/blob/master/CHANGELOG.md#​504httpsgithubcomwebpack-contribcopy-webpack-plugincomparev503v504-2019-07-26) [Compare Source](https://togithub.com/webpack-contrib/copy-webpack-plugin/compare/v5.0.3...v5.0.4)

webpack/webpack

### [`v4.38.0`](https://togithub.com/webpack/webpack/releases/v4.38.0) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.37.0...v4.38.0) ### Performance - Improved performance of ProgressPlugin - Improved performance of chunk graph generation - This can boost performance when many chunks are used, especially incremental build performance - Modules from parent chunks are now tracked during chunk graph generation, which allows to skip these modules in async chunks. This often renders `optimization.removeAvailableModules` unneeded, expect in scenarios where chunks are merged during optimization. - `optimization.removeAvailableModules` is now disabled in development mode by default - `optimization.removeAvailableModules` will be disabled for all modes in next major release, feel free to disable it in production too if you want extra performance. ### [`v4.37.0`](https://togithub.com/webpack/webpack/releases/v4.37.0) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.36.1...v4.37.0) ### Features - add logging API (see [#​9436](https://togithub.com/webpack/webpack/pull/9436) for details)
