Overview

Tailwind CSS 4.3.2 was released on June 29, 2026. This is a patch release focused entirely on bug fixes across the CLI, Vite plugin, PostCSS plugin, and core utility engine.

Fixed

• Prevent @tailwindcss/cli in --watch mode from crashing on Windows when @source points to a nonexistent directory
• Prevent @tailwindcss/vite from crashing in Deno v2.8.x when context.parentURL is not a valid URL
• Ensure CLI watch mode rebuilds when the input CSS file changes in an ignored directory
• Allow @variant rules used in addBase(...) to use custom variants defined later
• Prevent @tailwindcss/vite from crashing during HMR when scanned files or directories are deleted
• Generate font-size instead of color declarations for text-[--spacing(...)]
• Prevent @source patterns from scanning unrelated sibling files and folders
• Extract class candidates adjacent to Template Toolkit delimiters in .tt, .tt2, and .tx files
• Prevent @position-try rules from triggering unknown at-rule warnings when optimizing CSS
• Support class suggestions for named opacity modifiers from --opacity theme values
• Prevent type errors in @tailwindcss/postcss when used with newer PostCSS patch releases
