Tailwind CSS 4.2 Ships Webpack Plugin, New Palettes and Logical Property Utilities

Tailwind CSS 4.2.0 ships a first-class webpack plugin that eliminates the need for manual PostCSS configuration, bringing webpack projects to parity with Vite integration. The release adds four new muted color palettes (mauve, olive, mist, taupe), expands logical property utilities for internationalized and RTL layouts, and delivers a 3.8x recompilation speed improvement across all integrations. Teams still on v3 can use the automated migration tool, though some rough edges remain around @apply usage in component libraries.
