v4.3.4

Compare Source

Added
  • Add @tailwindcss/turbopack, a Turbopack loader for using Tailwind CSS with Next.js (#​20367)
Fixed
  • Ensure watch mode detects changes to symlinked @source files whose real paths aren't otherwise scanned (#​20356)
  • Ensure variants using @scope wrap generated utilities instead of nesting inside them (#​20369)
  • Ensure nested @scope rules preserve their scoping semantics when flattened (#​20369)
  • Preserve declarations directly inside @scope by wrapping them in :where(:scope) (#​20369)
  • Ensure generated utilities include a space in empty var() fallbacks (e.g. var(--tw-blur,) → var(--tw-blur, )) (#​20373)
  • Canonicalization: convert arbitrary breakpoint and container query variants to named equivalents (e.g. max-[64rem]:flex → max-lg:flex) (#​20380)
  • Prevent @tailwindcss/vite from crashing on every edit under Vite's experimental bundledDev mode (#​20379)
  • Ensure @tailwindcss/oxide falls back to WASM on platforms without native bindings (#​20383)
  • Extract class candidates from Ruby %w and %W literals using angle brackets or custom delimiters (e.g. %w<flex>, %w|flex|), including in Slim and Haml templates (#​20387)
  • Preserve whitespace in --default(…) values in functional @utility definitions (e.g. --default(box alphabetic) no longer becomes boxalphabetic) (#​20392)
  • Ensure automatic source detection respects negation-based .gitignore files (e.g. /* followed by !/… patterns) (#​20397)
  • Ensure root theme('…') namespace lookups in JavaScript plugins and config files return the full namespace object instead of the value of its DEFAULT key (#​20399)
  • Skip ignored directories when generating watch globs instead of walking their contents on every rebuild (#​20408)
  • Drop invalid UTF-8 candidates during class detection (#​20389)
  • Prevent @tailwindcss/vite from forcing full-page reloads for scanned files that Vite does not handle as modules (e.g. .php files) (#​20414)
  • Canonicalization: don't merge utilities that reference different theme variables set to CSS-wide keywords like unset (#​20417)
  • Don't generate utilities when a modifier is used that would otherwise be silently ignored (e.g. rounded-sm/[5], shadow-sm/foo, stroke-2/50) (#​20419)
  • Preserve and, or, and not inside selectors in supports-[…] variants (e.g. supports-[selector(a:not(.foo))]:flex) (#​20420)
  • Don't warn about Angular's ::ng-deep and :host-context() when optimizing CSS (#​20434)
  • Don't generate CSS for candidates containing an empty additional modifier (e.g. bg-red-500/50/ and group-hover/foo//bar:flex) (#​20466)
  • Ensure min-*, max-*, and container query variants with decimal values are sorted numerically (e.g. min-[40.25rem] before min-[40.5rem]) (#​20512)
  • Ensure CSS comments ending with \*/ are closed correctly instead of swallowing the CSS that follows (e.g. /* C:\temp\*/) (#​20508)
  • Improve style invalidation performance of group-* and peer-* variants (#​20513)
  • Ensure cached compilers release their loadModule and loadStylesheet callbacks after compilation (#​20531)
  • Canonicalization: preserve & when moving a pseudo-element into * or ** (e.g. [&_::before]:flex → **:[&::before]:flex) (#​20550)
  • Ensure the Set.prototype.intersection polyfill in canonicalizeCandidates(…) returns the intersection instead of the first set on Node.js < 22 (#​20562)
  • Canonicalization: ensure inline theme(…) alphas with more than 2 decimals migrate to a percentage modifier with the same opacity (e.g. theme(colors.red.500/.12345) → text-red-500/[12.345%], not text-red-500/[12.345]) (#​20563)
  • Canonicalization: preserve inline theme(…) alphas as an arbitrary percentage when a custom --opacity-* theme value would change the opacity (e.g. theme(colors.red.500/50%) → text-red-500/[50%] with --opacity-50: 10%) (#​20563)
  • Ensure the @property fallback isn't applied in Safari versions that no longer support margin-trim: inline (#​20569)
  • Treat viewport units like dvmin and svi and font-relative units like cap and rex as lengths in arbitrary values (e.g. text-[10dvmin] generates font-size instead of color) (#​20516)
  • Write plugin logs to stderr in tailwindcss canonicalize so they don't end up in the results on stdout (#​20561)
  • Extract class shorthands on later lines when Pug text, comments, or quoted attribute values contain unbalanced brackets, or a quote that doesn't start a string (e.g. input(pattern=/"/.source)) (#​20547, #​20572)
  • Underline the correct occurrence of an unsupported data type in --value(…) warnings (#​20554)
  • Canonicalization: prefer an existing candidate when collapsing utilities over another utility with the same default theme value (e.g. text-foreground text-primary → text-primary, not text-card-checked-border) (#​20540)
  • Canonicalization: don't collapse utilities into a utility that uses another theme variable with the same default value (e.g. mt-card mb-card → my-card, not my-4) (#​20574)
  • Ensure @tailwindcss/postcss rewrites relative url(…)s of stylesheets that are inlined before it runs (e.g. @imports in Vite) in optimized builds (#​20576)
  • Drop nested rules that put a combinator after a pseudo-element when using pseudo-element variants (e.g. selection:* on a utility with a nested & > * rule) (#​20575)
  • Don't generate CSS for arbitrary values with unbalanced parentheses or brackets (e.g. w-[calc(1px] or [--x:a[b]) (#​20577)
  • Canonicalization: prevent collapse: true from taking exponentially longer when classes are linked through a utility that sets many properties (e.g. sr-only) (#​20558)
  • Ensure & is substituted inside :-moz-any(…) and :-webkit-any(…) in custom variants (e.g. @custom-variant firefox (:-moz-any(&));) (#​20486)
  • Ensure the standalone macOS binaries have a valid code signature, so macOS 27 no longer kills them at launch (#​20578)
  • Ensure @tailwindcss/turbopack and @tailwindcss/webpack rebuild when the input CSS changes (e.g. next dev with Turbopack no longer serves the CSS of the previous edit) (#​20582)
  • Canonicalization: don't drop a utility that sets a --tw-* variable when an unrelated property has the same value (e.g. link mt-4 no longer becomes mt-4 when link sets margin-top: 16px and --tw-translate-x: 16px) (#​20593)
  • Decode single-digit hexadecimal escapes in theme variable and @utility names as the CSS spec does (e.g. @theme { --color-\0: red; } no longer registers --color-0) (#​20591)
  • Don't treat !important inside strings, comments or url() in declaration values as the important flag (e.g. content: "a !important b") (#​20627)
  • Parse a custom property at the end of the input when it has no trailing ; (e.g. --foo: bar as the last declaration) (#​20653)
  • Keep a declaration without a ; at the end of the CSS input (e.g. color: red) (#​20655)
