Sourced from tailwindcss's releases.

v4.3.1

Added

Fixed

• Remove deprecation warnings by using Module#registerHooks instead of Module#register on Node 26+ (#20028)
• Canonicalization: don't crash when plugin utilities throw for unsupported values (#20052)
• Allow @apply to be used with CSS mixins (#19427)

• Ensure @tailwindcss/webpack can be installed in Rspack projects without requiring webpack as a peer dependency (#20027)
• Canonicalization: don't suggest invalid calc(…) expressions (e.g. px-[calc(1rem+0px)] → px-[calc(1rem+0)]) (#20127)
• Canonicalization: avoid suggesting large spacing-scale values for arbitrary lengths (e.g. left-[99999px] → left-[99999px], not left-24999.75) (#20130)
• Ensure @tailwindcss/cli in --watch mode recovers when a tracked dependency is deleted and restored (#20137)

• Ensure explicitly referenced @source directories are scanned even when ignored by git (#20214)
• Ensure @source globs ending in **/* preserve dynamic path segments to avoid scanning too many files (#20217)
• Canonicalization: don't fold calc(…) divisions when the result would require high precision (e.g. w-[calc(100%/3.5)] → w-[calc(100%/3.5)], not w-[28.571428571428573%]) (#20221)
• Serve ESM type declarations to ESM importers of @tailwindcss/postcss (#20228)

Changed

• Generate 0 instead of calc(var(--spacing) * 0) for spacing utilities like m-0 and left-0 (#20196)
