• 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)
• Generate var(--spacing) instead of calc(var(--spacing) * 1) for spacing utilities like m-1 and left-1 (#​20196)

Compare Source

Added

• Add @container-size utility (#​18901)

• Add zoom-* utilities (#​20020)
• Add tab-* utilities (#​20022)

• Resolve imports relative to base when result.opts.from is not provided when using @tailwindcss/postcss (#​19980)
• Canonicalization: preserve significant _ whitespace in arbitrary values (#​19986)
• Canonicalization: add parentheses when removing whitespace from arbitrary values would hurt readability (e.g. w-[calc(100%---spacing(60))] → w-[calc(100%-(--spacing(60)))]) (#​19986)
• Canonicalization: preserve the original unit in arbitrary values instead of normalizing to base units (e.g. -mt-[20in] → mt-[-20in], not mt-[-1920px]) (#​19988)
• Canonicalization: migrate arbitrary :has() variants from [&:has(…)] to has-[…] (#​19991)

• Export missing PluginWithConfig type from tailwindcss/plugin to fix errors when inferring plugin config types (#​19707)

• Canonicalization: preserve required whitespace around operators in negated arbitrary values (e.g. -left-[(var(--a)+var(--b))]) (#​20011)

• Ensure query params in imports are considered unique resources when using @tailwindcss/webpack (#​19723)
