Release Notes

tailwindlabs/tailwindcss (@​tailwindcss/vite)

v4.3.3

Compare Source

Fixed

• Support --watch --poll[=ms] in @tailwindcss/cli when filesystem events are unreliable or unavailable (#​20297)
• Canonicalization: match arbitrary hex colors against theme colors case-insensitively (e.g. bg-[#fff] and bg-[#FFF] → bg-white) (#​20298)
• Prevent Preflight from overriding Firefox's native iframe:focus-visible outline styles (#​20292)
• Ensure theme('colors.foo') in JS plugins resolves correctly when both --color-foo and --color-foo-bar exist (#​20299)
• Ensure fractional opacity modifiers work with named shadow sizes like shadow-sm/12.5, text-shadow-sm/12.5, drop-shadow-sm/12.5, and inset-shadow-sm/12.5 (#​20302)
• Parse selectors like [data-foo]div as two selectors instead of one (#​20303)
• Ensure @tailwindcss/postcss rebuilds when a preprocessor like Sass changes the input CSS without changing the input file on disk (#​20310)
• Ensure CSS nesting is handled even when Lightning CSS isn't run, such as in @tailwindcss/browser and Tailwind Play (#​20124)
• Prevent achromatic theme colors from shifting hue when mixed in polar color spaces like oklch (#​20314)
• Ensure --spacing(0) is optimized to 0px instead of 0 so it remains a <length> when used in calc(…) (#​20319)
• Load @parcel/watcher only when needed in @tailwindcss/cli --watch mode, so one-off builds and --watch --poll work when @parcel/watcher can't be loaded (#​20325)
• Use explicit platform fonts instead of system-ui and ui-sans-serif so CJK text respects the page's lang attribute on Windows (#​20318)
• Prevent @tailwindcss/upgrade from rewriting ignored files when run from a subdirectory (#​20329)
• Ensure earlier @source rules pointing to nested files are scanned when later @source rules point to files in parent folders (#​20335)

v4.3.2

Compare Source

Fixed

• Support bare spacing values for auto-rows-* and auto-cols-* utilities (e.g. auto-rows-12 and auto-cols-16) (#​20229)
• Prevent @tailwindcss/cli in --watch mode from crashing on Windows when @source points to a directory that doesn't exist (#​20242)
• Prevent @tailwindcss/vite from crashing in Deno v2.8.x when context.parentURL is not a valid URL (#​20245)
• Ensure @tailwindcss/cli in --watch mode rebuilds when the input CSS file changes in an ignored directory (#​20246)
• Allow @variant rules used in addBase(…) to use custom variants defined later (#​20247)
• Prevent @tailwindcss/vite from crashing during HMR when scanned files or directories are deleted (#​20259)
• Generate font-size instead of color declarations for text-[--spacing(…)] (#​20260)
• Prevent @source patterns from scanning unrelated sibling files and folders (#​20263)
• Extract class candidates adjacent to Template Toolkit delimiters like %]…[% in .tt, .tt2, and .tx files (#​20269)
• Extract class candidates from conditional Maud syntax like p.text-black[condition] (#​20269)
• Prevent @position-try rules from triggering unknown at-rule warnings when optimizing CSS (#​20277)
• Support class suggestions for named opacity modifiers from --opacity theme values (#​20287)
• Prevent type errors in @tailwindcss/postcss when used with newer PostCSS patch releases (#​20289)

• 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 standalone @tailwindcss/cli binaries are ignored when scanning for class candidates (#​20139)

• Serve ESM type declarations to ESM importers of @tailwindcss/postcss (#​20228)
