([#3083](https://github.com/mui/base-ui/pull/3083)) ## 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.

([#3133](https://github.com/mui/base-ui/pull/3133)) ## Tooltip - **Breaking change:** Support detached triggers.<br /> `delay` and `closeDelay` props have been moved from `<Tooltip.Root>` to `<Tooltip.Trigger>`. ([#3071](https://github.com/mui/base-ui/pull/3071)) - **Breaking change:** Change `hoverable` to `disableHoverablePopup`.<br /> In case you need to disable the hoverable popup behavior, be sure to add the `disableHoverablePopup` prop.
