 -   Default `--wp-admin-theme-color` to `#3858e9`, the WordPress 7.0 default admin color scheme, instead of the legacy `#007cba`. To keep the old color, include `admin-scheme(#007cba)` on `:root` in your own stylesheet. `wordpress-admin-schemes()` and the default custom properties now set `#007cba` for the Fresh scheme, which had used the `:root` default ([#83749](https://github.com/WordPress/gutenberg/pull/83749)).
 -   `radio-control`: Use the design system color tokens ([#83270](https://github.com/WordPress/gutenberg/pull/83270)).

+-   `RadioControl`: Keep radio circles visually 16px at all viewport widths while retaining a 24px pointer target ([#83840](https://github.com/WordPress/gutenberg/pull/83840)).
 -   `Text`: Make single-line truncation and `isBlock` overrides consistent across the main document and iframes ([#82573](https://github.com/WordPress/gutenberg/pull/82573)).
 -   `CardDivider`: Apply the Card's width, display, and border color consistently inside iframes ([#82577](https://github.com/WordPress/gutenberg/pull/82577)).
 -   `BorderControl`, `BorderBoxControl`: Stop offering `%` as a width unit, since `border-width` does not accept percentages. A width already set in `%` keeps showing its unit ([#83492](https://github.com/WordPress/gutenberg/pull/83492)).
