-<h2>3.0.0 -&gt; 3.1.0</h2>The PDF editor now supports descriptive PDF
+<h2>3.0.0 -&gt; 3.1.0</h2>There is a new object-oriented library to
+generate HTML for the account modules (e.g. used for
+display_html_attributes()). This will allow additional functionality
+like client side validation. Please see lib/html.inc or package
+metaHTML in the phpdoc documentation.<br>
+<span style="color: red; font-weight: bold;">Attention: The old array-based meta HTML elements will only be supported until Q2/2011!</span><br>
+<br>
+The PDF editor now supports descriptive PDF
 fields. You can use this by returning an associative array for the PDF
 fields (e.g. array('macAddress' =&gt; _('MAC address'))) in <span style="font-weight: bold;">get_pdfFields()</span> or the meta data.<br>
 The old format is still supported. LAM will continue to show the field name as label in this case.<br>
