+Changes text overflow styling in Markdown content
+
+⚠️ **Potentially breaking change:** This release switches the [`overflow-wrap`](https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap) CSS style for common elements to `break-word`. In most cases, there should be little visual impact, but this change can impact how layouts with implicit sizing (such as tables) look, improving legibility in how words wrap.
+
+If you want to preserve the previous styling, you can add the following [custom CSS](https://starlight.astro.build/guides/css-and-tailwind/#custom-css-styles) to your site:
+
+```css
+p, h1, h2, h3, h4, h5, h6, code {
+  overflow-wrap: anywhere;
+}
+```
