       <li>The icons, now <code>.glyphicon</code>, are now font based. Icons also require a base and icon class (e.g. <code>.glyphicon .glyphicon-asterisk</code>).</li>
       <li>Typeahead has been dropped, in favor of using <a href="http://twitter.github.io/typeahead.js/">Twitter Typeahead</a>.</li>
       <li>Modal markup has changed significantly. The <code>.modal-header</code>, <code>.modal-body</code>, and <code>.modal-footer</code> sections are now wrapped in <code>.modal-content</code> and <code>.modal-dialog</code> for better mobile styling and behavior.</li>
+      <li>The HTML loaded by the <code>remote</code> modal option is now injected into the <code>.modal</code> instead of into the <code>.modal-body</code>. This allows you to also easily vary the header and footer of the modal, not just the modal body.</li>
       <li>JavaScript events are namespaced. For example, to handle the modal "show" event, use <code>'show.bs.modal'</code>. For tabs "shown" use <code>'shown.bs.tab'</code>, etc..</li>
