- `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.

### Important Note for npm users
This release updates some dependencies, which may trigger a npm bug. See [here for the webpack issue](https://togithub.com/webpack/webpack/issues/8656). The [npm bug](https://npm.community/t/packages-with-peerdependencies-are-incorrectly-hoisted/4794) has [been fixed](https://togithub.com/npm/cli/pull/147), but a new npm version has not been released yet.
For workarounds see [this comment](https://togithub.com/webpack/webpack/issues/8656#issuecomment-456713191).
Eventually the fix will be to upgrade npm once the bugfix is released.

[Compare Source](https://togithub.com/webpack/webpack/compare/v4.25.1...v4.26.0)
### Features
- Switch from uglify-es to terser as default minimizer
Note: While they are officially backward-compatible, it can still happen that a new bugs occurs with terser, which break your production builds. Make sure to validate your production builds after upgrading to this version. (Note that it's always a good idea to test your output assets before deploying.)
If you want to report bugs to terser (), please provide a minimal repro case with minimized and **non-minimized** code. You can configure webpack to generate non-minimized code in production mode by setting `optimization.minimize: false`. When reporting a bug to terser, best report a repro case which doesn't require running webpack and is reproducible with only the terser command line.
See [`optimization.minimizers`](https://webpack.js.org/configuration/optimization/#optimization-minimizer) configuration option to switch back to uglify-es or provide additional minimize options for terser.

See [here for the webpack issue](https://togithub.com/webpack/webpack/issues/8656). The [npm bug](https://npm.community/t/packages-with-peerdependencies-are-incorrectly-hoisted/4794) has [been fixed](https://togithub.com/npm/cli/pull/147), but a new npm version has not been released yet. For workarounds see [this comment](https://togithub.com/webpack/webpack/issues/8656#issuecomment-456713191). Eventually the fix will be to upgrade npm once the bugfix is released. ### Features - update acorn to v6 - limit the number of in parallel written output files to 15 - add `output.futureEmitAssets` which gives the emitting logic of webpack 5 - assets are replaced with SizeOnlySources - reading assets after emitting is no longer allowed - This allows memory to be garbage-collected ### [`v4.28.4`](https://togithub.com/webpack/webpack/releases/v4.28.4) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.3...v4.28.4) ### Bugfixes - `ProfilingPlugin` creates output path if not existing - fixed support for arrow function functions for `optimization.minimizer` - failed hooks is now also called when `run()` fails ### [`v4.28.3`](https://togithub.com/webpack/webpack/releases/v4.28.3) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.2...v4.28.3) ### Bugfixes - ProfilingPlugin creates the output folder if necessary ### [`v4.28.2`](https://togithub.com/webpack/webpack/releases/v4.28.2) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.1...v4.28.2) ### Bugfixes - fixes a crash when multiple IgnorePlugins are used ### [`v4.28.1`](https://togithub.com/webpack/webpack/releases/v4.28.1) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.28.0...v4.28.1) ### Bugfixes - fix error in IgnorePlugin when no contextRegExp is passed ### [`v4.28.0`](https://togithub.com/webpack/webpack/releases/v4.28.0) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.27.1...v4.28.0) ### Features - IgnorePlugin: `checkResource` has an additional `context` argument ### Bugfixes - Injection of node.js globals has been disabled for `.mjs` files as it's crashing ### [`v4.27.1`](https://togithub.com/webpack/webpack/releases/v4.27.1) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.27.0...v4.27.1) ### Bugfixes - v4.27.0 accidentially introduced a breaking change.
