+	  <p>This release fixes a vulnerability with Synapse's URL preview feature. URL previews
+	  of some web pages can lead to unbounded recursion, causing the request to either fail,
+	  or in some cases crash the running Synapse process.</p>
+	  <p>Note that:</p>
+	  <ul>
+	    <li>Homeservers with the url_preview_enabled configuration option set to false
+	    (the default value) are unaffected.</li>
+	    <li>Instances with the enable_media_repo configuration option set to false are
+	    also unaffected, as this also disables the URL preview functionality.</li>
+	  </ul>
