Having two functions is a bit much, particularly because there are more URLs you might want to change (or which might be unsafe so *we* make them safe). And their name and APIs were a bit weird. You can use the new `urlTransform` prop instead to change all your URLs. ##### Remove `linkTarget` The `linkTarget` option was removed; you should likely not set targets. If you want to, use [`rehype-external-links`](https://togithub.com/rehypejs/rehype-external-links). ##### Remove `includeElementIndex` The `includeElementIndex` option was removed, so `index` is never passed to components. Write a plugin to pass `index`:

Show example of plugin

```jsx import {visit} from 'unist-util-visit' function rehypePluginAddingIndex() { /** * @​param {import('hast').Root} tree * @​returns {undefined} */ return function (tree) { visit(tree, function (node, index) { if (node.type === 'element' && typeof index === 'number') { node.properties === index } }) } } ```

##### Remove `rawSourcePos` The `rawSourcePos` option was removed, so `sourcePos` is never passed to components. All components are passed `node`, so you can get `node.position` from them. ##### Remove `sourcePos` The `sourcePos` option was removed, so `data-sourcepos` is never passed to elements. Write a plugin to pass `index`:

Show example of plugin

```jsx import {stringifyPosition} from 'unist-util-stringify-position' import {visit} from 'unist-util-visit' function rehypePluginAddingIndex() { /** * @​param {import('hast').Root} tree * @​returns {undefined} */ return function (tree) { visit(tree, function (node) { if (node.type === 'element') { node.properties.dataSourcepos = stringifyPosition(node.position) } }) } } ```

##### Remove extra props passed to certain components When overwriting components, these props are no longer passed: - `inline` on `code` — create a plugin or use `pre` for the block - `level` on `h1`, `h2`, `h3`, `h4`, `h5`, `h6` — check `node.tagName` instead - `checked` on `li` — check `task-list-item` class or check `props.children` - `index` on `li` — create a plugin - `ordered` on `li` — create a plugin or check the parent - `depth` on `ol`, `ul` — create a plugin - `ordered` on `ol`, `ul` — check `node.tagName` instead - `isHeader` on `td`, `th` — check `node.tagName` instead - `isHeader` on `tr` — create a plugin or check children
