 - The `button-outline-variant()` mixin now accepts an additional argument, `$active-color`, for setting the button's active state text color. By default, this parameter will find which color provides more contrast against the button's active background color with `color-contrast()`.
 - Ditch the Sass map merges, which makes it easier to remove redundant values. Keep in mind you now have to define all values in the Sass maps like `$theme-colors`. Check out how to deal with [Sass maps]({{< docsref "/customize/sass#maps-and-loops" >}}).
 - `color-yiq()` function and related variables are renamed to `color-contrast()` since it's not related to YIQ colorspace anymore. [See #30168.](https://github.com/twbs/bootstrap/pull/30168/)
-  - `$yiq-contrasted-threshold` is renamed `$min-contrast-ratio`.
