# Bun 1.4 发布：Rust 重写后首个稳定版，新增 Bun.WebView

JavaScript 运行时 Bun 1.4 正式发布，这是其在几个月前进行 Rust 重写后的首个稳定版本。新版带来了名为 Bun.WebView 的新功能，有开发者利用它实现了一个类似 shot-scraper 的 JSON API。值得注意的是，官方在发布说明中淡化了 Rust 重写的影响，但这一底层变化可能对未来性能和稳定性产生深远影响。

## English Version

**Bun 1.4 Released: First Stable Version After Rust Rewrite, Adds Bun.WebView**

Bun 1.4 has been released as the first stable version since its major Rust rewrite. A key new feature is Bun.WebView, which a developer has already used to build a shot-scraper-style JSON API. While the release notes downplayed the Rust rewrite, the change is significant and likely to impact performance and stability going forward.
