大约八个月前，我们在 Tailwind CSS v4.0 上发布了 开源我们的进展。经过数百小时的修复错误、令人心碎的向后兼容性工作以及 Windows CI 故障排查，我终于可以兴奋地发布第一个公测版本了。
¥About eight months ago we open-sourced our progress on Tailwind CSS v4.0. Hundreds of hours of fixing bugs, soul-crushing backward compatibility work, and troubleshooting Windows CI failures later, I'm excited to finally tag the first public beta release.
正如我在发布第一个 alpha 版本时提到的，Tailwind CSS v4.0 是一款全新的引擎，专为性能而打造，专为现代 Web 设计。
¥As I talked about when we published the first alpha, Tailwind CSS v4.0 is an all-new engine built for performance, and designed for the modern web.
-
性能卓越 - 新引擎的完整构建速度提升高达 5 倍，增量构建速度提升超过 100 倍 - 以微秒为单位。
¥Built for performance — full builds in the new engine are up to 5x faster, and incremental builds are over 100x faster — and measured in microseconds.
-
统一工具链 - 内置导入处理、供应商前缀和语法转换，无需额外工具。
¥Unified toolchain — built-in import handling, vendor prefixing, and syntax transforms, with no additional tooling required.
-
CSS 优先配置 - 重新构想的开发者体验，你可以直接在 CSS 中自定义和扩展框架，而无需使用 JavaScript 配置文件。
¥CSS-first configuration — a reimagined developer experience where you customize and extend the framework directly in CSS instead of a JavaScript configuration file.
-
专为现代 Web 设计 - 基于原生级联层和广色域色彩构建，并包含对容器查询、
@starting-style、弹出窗口等现代 CSS 功能的一流支持。¥Designed for the modern web — built on native cascade layers, wide-gamut colors, and including first-class support for modern CSS features like container queries,
@starting-style, popovers, and more.
