v4.3.1 shipped June 12 with a round of fixes for the utility engine and compatibility patches for Node 26.

**Scrollbar, zoom, and tab utilities close gaps with native CSS.** The scrollbar suite (`scrollbar-{auto,thin,none}`, `scrollbar-thumb-*`, `scrollbar-track-*`, `scrollbar-gutter-*`) maps directly to CSS `scrollbar-width` and `scrollbar-color`; `zoom-*` covers the `zoom` property; `tab-*` controls tab-size — all areas where developers previously needed custom CSS or a plugin. `@container-size` landed alongside these, enabling container queries that key on height as well as width.

**`@variant` gained stacked and compound forms.** You can now write `@variant hover:focus { … }` and `@variant hover, focus { … }` directly, and functional `@utility` definitions support `--default(…)` for fallback values.

**The class optimizer shrank your output more aggressively.** The canonicalization engine now collapses shorthand pairs (`px-[…] py-[…]` → `p-[…]`, `border-t-* border-b-*` → `border-y-*`), migrates legacy `:has()` variants to idiomatic `has-[…]` form, and preserves arbitrary value formatting faithfully without normalizing units to base pixels. v4.3.1 also patched a crash when plugin utilities throw for unsupported values, and fixed `not-*` negation of `@container style(…)` queries.

**`@apply` now works inside CSS mixins.** The module loader also switched to `Module#registerHooks` to silence Node 26 deprecation warnings.

**The Prettier plugin opened a public sorting API.** The `/sorter` subpath exports programmatic class ordering so tooling authors can reuse the logic outside Prettier. The release also dropped `recast` and `ast-types`, switched to directory-based config caching, and requires Prettier 3.7+.
