+
+    <h2>New: Markdown source view</h2>
+    <ul>
+      <li>Added a side-by-side view of raw Markdown source, with scrolling synchronized with the rendered view.</li>
+      <li>Find works across the rendered document and source pane.</li>
+      <li>Heading collapse state is mirrored between the rendered document and source pane.</li>
+    </ul>
+
+    <h2>Table of Contents updates</h2>
+    <ul>
+      <li>Made the table of contents pane resizable.</li>
+      <li>Made TOC width, visibility, and heading depth persistent.</li>
+      <li>Added optional TOC depth markers (bullets) and smoother active-heading tracking while scrolling long documents.</li>
+    </ul>
+
+    <h2>Customization and rendering polish</h2>
+    <ul>
+      <li>Improved scrollbar appearance by styling them to match the active theme.</li>
+      <li>Expanded the CSS help with custom CSS examples, document structure notes, and scrollbar styling selectors.</li>
+      <li>Fixed user-created theme overrides so they reliably take precedence over built-in themes.</li>
+    </ul>
