Changes to PostCSS Custom Properties

12.1.11 (December 1, 2022)

• Improve plugin performance

12.1.10 (October 20, 2022)

• Fix how preserve: false interacts with logic around duplicate code (see 12.1.9).

```diff :root { --my-order: 1; }

.foo { order: 1; order: var(--my-order); }

/ With preserve: false : /

.foo { order: 1; } ```

12.1.9 (September 14, 2022)

• Prevent duplicate code generation.

```diff .foo { order: 1; order: var(--my-order, 1); }

/ becomes /

.foo { order: 1; - order: 1; order: var(--my-order, 1); } ```

12.1.8 (June 10, 2022)

• Remove some unneeded regular expressions.
