v4 introduces the Oxide engine, a Rust-based build system offering dramatically faster build times, especially beneficial for large projects.

• Impact: Increased developer productivity through reduced wait times.

2. CSS-First Configuration: A Paradigm Shift

Configure styles directly within your CSS using @layer, @apply, and other Tailwind utilities.

• Example:

<code>  @layer utilities {
    .btn-primary {
      @apply bg-blue-500 text-white py-2 px-4 rounded;
    }
  }</code>

• Impact: Simplified configuration, less boilerplate, and alignment with modern CSS best practices.

3. Effortless Import Management

Built-in import handling simplifies the management of third-party plugins and custom styles.

• Impact: Eliminates the need for external tools like PostCSS, streamlining the build process.

4. Automated Vendor Prefixing and Syntax Transformations

Cross-browser compatibility is ensured through automatic vendor prefixing and syntax transformations.

• Impact: Focus on clean code without worrying about browser-specific issues.

5. Smaller, Faster Builds with Optimized PurgeCSS

The new engine optimizes unused CSS removal, resulting in significantly smaller build sizes.
