## Preview Card

- **Breaking change:** Move delay props to trigger.<br />
  If you were using `delay` or `closeDelay` props, be sure to move them to from `<PreviewCard.Root>` to the `<PreviewCard.Trigger>` component.

## Radio Group

- **Breaking change:** Render root as `<span>` instead of `<button>`
  ([#3205](https://github.com/mui/base-ui/pull/3205))

## Scroll Area

- **Breaking change:** Improve CSS vars performance.<br />

  ([#3156](https://github.com/mui/base-ui/pull/3156))

## Select

  The trigger now renders a `<button>` element, be sure to adjust your code if necessary.

## Slider

- **Breaking change:** Add `thumbCollisionBehavior` prop.<br />
  In range sliders, moving a thumb with a pointer will now push other thumbs it collides with to avoid blocking drag movements by default (the default value is `push`).<br />
  The value `swap` was also added, which allows thumbs to be dragged past each other when they collide.<br />
  Lastly, the value `none` is the same as the previous behavior, where thumbs can't be dragged past one another.<br />
  Keyboard interactions always use `none` behavior.
