Release Notes

webpack/webpack

### [`v4.32.0`](https://togithub.com/webpack/webpack/releases/v4.32.0) [Compare Source](https://togithub.com/webpack/webpack/compare/v4.31.0...v4.32.0) ### Features - Added `this.mode` to the loader API, to allow loaders to choose defaults by `mode` similar to webpacks options - Stack Trace for Errors in rejected Promises from `import()` now includes the stack from where the `import()` was called ### Bugfixes - The Parser can now analyse identifiers in rest patterns too - `const { a, ...rest } = obj`, where `rest` conflicts with an imported binding etc. - `node: false` now correctly disables `__dirname` and `__filename` too - `__dirname` and `__filename` now no longer evaluates to something when `node: false` or `node.__file/dirname: false` is set - `if(__dirname !== "")` is no longer replaced with `if(true)` in such scenarios - prefetching chunks is no executed **after** the initial module evaluation - This allows to override i. e. `__webpack_public_path__` for prefetching too - fixes a runtime crash when using side-effect-free modules with the DllPlugin ### Contribute - CI tests node.js 12 now too - webpack-bot now merges dependabot PRs automatically when status checks succeed
