### [`v2.57.0`](https://togithub.com/rollup/rollup/blob/master/CHANGELOG.md#2570)
[Compare Source](https://togithub.com/rollup/rollup/compare/v2.56.3...v2.57.0)
*2021-09-22*
##### Features
- Add `generatedCode` option to allow Rollup to use es2015 features for smaller output and more efficient helpers ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Improve AMD and SystemJS parsing performance by wrapping relevant functions in parentheses ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Using `preferConst` will now show a warning with `strictDeprecations: true` ([#4215](https://togithub.com/rollup/rollup/issues/4215))
##### Bug Fixes
- Improve ES3 syntax compatibility by more consequently quoting reserved words as props in generated code ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Do not use `Object.assign` in generated code to ensure ES5 compatibility without the need for polyfills ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Support live-bindings in dynamic namespace objects that contain reexported external or synthetic namespaces ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Use correct "this" binding in dynamic import expressions for CommonJS and AMD ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Properly handle `shimMissingExports` for exports that are only used internally ([#4215](https://togithub.com/rollup/rollup/issues/4215))
- Prevent unhandled rejection for failed module parsing ([#4228](https://togithub.com/rollup/rollup/issues/4228))
