--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

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

@source

rules pointing to nested files are scanned when later
