  ([#1962](https://github.com/mui/base-ui/pull/1962))
- **Breaking change:** Avoid removing limited toasts from the DOM.
  The `[data-limited]` styles in the demos were updated to handle limited toasts remaining in the DOM. They should now be a standalone style as `&[data-limited] { opacity: 0 }`.
  ([#1953](https://github.com/mui/base-ui/pull/1953))

- Add `collisionAvoidance` prop ([#1849](https://github.com/mui/base-ui/pull/1849))

## useRender

- **Breaking change:** Performance/refactor: `useRender`. An object with a `renderElement` property is no longer returned; instead, the hook returns the element directly (`const element = useRender(...)`). The `refs` option was also renamed to `ref`.
  ([#1934](https://github.com/mui/base-ui/pull/1934))
- Skip most of useRenderElement logic when unnecessary ([#1967](https://github.com/mui/base-ui/pull/1967))
