What's New in 4.1

New Features

CSS-first `@theme` configuration - no JS config file needed
Native cascade layers and container query support

Improvements

Automatic content detection - no more `content` globs to maintain
Better IntelliSense for custom design tokens

Performance

Full rebuilds up to 5x faster with the new Oxide engine
Incremental builds measured in microseconds for cached utilities

Bug Fixes

Fixed a specificity conflict between arbitrary values and variants
Corrected dark-mode class ordering in generated CSS

Tailwind CSS v4 moved to a CSS-first configuration model and a new Rust-based engine (Oxide), dramatically cutting build times and simplifying setup - no more `tailwind.config.js` required for most projects.
