+"markdown-to-jsx": patch

+
+Browsers assign element with `id` to the global scope using the value as the variable name. E.g.: `<h1 id="analytics">` can be referenced via `window.analytics`.
+This can be a problem when a name conflict happens. For instance, pages that expect `analytics.push()` to be a function will stop working if the an element with an `id` of `analytics` exists in the page.
+
+In this change, we export the `slugify` function so that users can easily augment it. 
+This can be used to avoid variable name conflicts by giving the element a different `id`.
+
+```js
+import { slugify } from 'markdown-to-jsx';
+
+options={{
+  slugify: str => {
+    let result = slugify(str)
+
+    return result ? '-' + str : result;
+  }
+}}
+```
