### v2.16.0

- Date: 2025-09-18
- Version: v2.16.0
- Original notes: https://github.com/parcel-bundler/parcel/releases/tag/v2.16.0
- Permalink: https://whatsnew.fyi/product/parcel/releases/v2.16.0

This release significantly improves code splitting and tree shaking when scope hoisting is disabled, e.g. when using React Server Components with static rendering. It enables re-exports to be followed when resolving a dependency, so that only used exports from large libraries get bundled together for each page rather than across all pages. This was already the case when using scope hoisting, but now it works without scope hoisting as well.

- JavaScript
  - Code split re-exports when scope hoisting is disabled – [Details](https://github.com/parcel-bundler/parcel/pull/10207)
