 - Dropped `color()`, `theme-color()` & `gray()` functions in favor of variables. [See #29083](https://github.com/twbs/bootstrap/pull/29083)
 - The `theme-color-level()` function is renamed to `color-level()` and now accepts any color you want instead of only `$theme-color` colors. [See #29083](https://github.com/twbs/bootstrap/pull/29083)
