 - Resolve imports relative to `base` when `result.opts.from` is not provided when using `@tailwindcss/postcss` ([#19980](https://github.com/tailwindlabs/tailwindcss/pull/19980))
 - Canonicalization: preserve significant `_` whitespace in arbitrary values ([#19986](https://github.com/tailwindlabs/tailwindcss/pull/19986))

 - Allow multiple `@utility` definitions with the same name but different value types ([#19777](https://github.com/tailwindlabs/tailwindcss/pull/19777))
 - Export missing `PluginWithConfig` type from `tailwindcss/plugin` to fix errors when inferring plugin config types ([#19707](https://github.com/tailwindlabs/tailwindcss/pull/19707))
 - Allow `@apply` to be used with CSS mixins ([#19427](https://github.com/tailwindlabs/tailwindcss/pull/19427))
 - Ensure `start` and `end` legacy utilities without values do not generate CSS ([#20003](https://github.com/tailwindlabs/tailwindcss/pull/20003))
+- Ensure `--value(…)` is required in functional `@utility` definitions ([#20005](https://github.com/tailwindlabs/tailwindcss/pull/20005))
