 ### Fixed
 
 - Ensure watch mode detects changes to symlinked `@source` files whose real paths aren't otherwise scanned ([#20356](https://github.com/tailwindlabs/tailwindcss/pull/20356))
-- Ensure custom variants using `@scope` wrap the generated utilities instead of nesting inside them ([#20369](https://github.com/tailwindlabs/tailwindcss/pull/20369))
+- Ensure variants using `@scope` wrap generated utilities instead of nesting inside them ([#20369](https://github.com/tailwindlabs/tailwindcss/pull/20369))
-- Fix flattening of `@scope` at-rules ([#20369](https://github.com/tailwindlabs/tailwindcss/pull/20369))
+- Ensure nested `@scope` rules preserve their scoping semantics when flattened ([#20369](https://github.com/tailwindlabs/tailwindcss/pull/20369))
-- Fix standalone declarations in `@scope`, wrap them in `:where(:scope)` ([#20369](https://github.com/tailwindlabs/tailwindcss/pull/20369))
+- Preserve declarations directly inside `@scope` by wrapping them in `:where(:scope)` ([#20369](https://github.com/tailwindlabs/tailwindcss/pull/20369))

+- Ensure generated utilities include a space in empty `var()` fallbacks (e.g. `var(--tw-blur,)` → `var(--tw-blur, )`) ([#20373](https://github.com/tailwindlabs/tailwindcss/pull/20373))

+- Canonicalization: convert arbitrary breakpoint and container query variants to named equivalents (e.g. `max-[64rem]:flex` → `max-lg:flex`) ([#20380](https://github.com/tailwindlabs/tailwindcss/pull/20380))
 - Prevent `@tailwindcss/vite` from crashing on every edit under Vite's experimental `bundledDev` mode ([#20379](https://github.com/tailwindlabs/tailwindcss/pull/20379))

+- 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](https://github.com/tailwindlabs/tailwindcss/pull/20387))
-- Preserve whitespace in `--default(…)` values in custom functional utilities (e.g. `--default(box alphabetic)` no longer becomes `boxalphabetic`) ([#20392](https://github.com/tailwindlabs/tailwindcss/pull/20392))
+- Preserve whitespace in `--default(…)` values in functional `@utility` definitions (e.g. `--default(box alphabetic)` no longer becomes `boxalphabetic`) ([#20392](https://github.com/tailwindlabs/tailwindcss/pull/20392))
-- Don't scan gitignored directories (e.g. `node_modules` and `.git`) when the project uses a safelist-style `.gitignore` (e.g. `/*` followed by `!/…` negations) ([#20397](https://github.com/tailwindlabs/tailwindcss/pull/20397))
+- Ensure automatic source detection respects negation-based `.gitignore` files (e.g. `/*` followed by `!/…` patterns) ([#20397](https://github.com/tailwindlabs/tailwindcss/pull/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](https://github.com/tailwindlabs/tailwindcss/pull/20399))

+- Drop invalid UTF-8 candidates during class detection ([#20389](https://github.com/tailwindlabs/tailwindcss/pull/20389))
-- `@tailwindcss/vite` no longer forces a full page reload for external files (e.g.: `.php` files) ([#20414](https://github.com/tailwindlabs/tailwindcss/issues/20414))
+- Prevent `@tailwindcss/vite` from forcing full-page reloads for scanned files that Vite does not handle as modules (e.g. `.php` files) ([#20414](https://github.com/tailwindlabs/tailwindcss/pull/20414))
 - Canonicalization: don't merge utilities that reference different theme variables set to CSS-wide keywords like `unset` ([#20417](https://github.com/tailwindlabs/tailwindcss/pull/20417))

-- Only normalize top-level `and`, `or`, and `not` keywords in `supports-[…]` variants (e.g. `selector(a: not (.foo))` → `selector(a:not(.foo))`) ([#20420](https://github.com/tailwindlabs/tailwindcss/pull/20420))
+- Preserve `and`, `or`, and `not` inside selectors in `supports-[…]` variants (e.g. `supports-[selector(a:not(.foo))]:flex`) ([#20420](https://github.com/tailwindlabs/tailwindcss/pull/20420))
