        <p>
          A maintenance release that fixes a 
<a href="http://www.w3.org/Bugs/Public/buglist.cgi?product=Validator&amp;target_milestone=0.6.6">few minor bugs</a>, 
	  resurrects the
          whitespace-preserving source display, adds explanations for additional
          error messages, and makes some slight tweaks to the website style.
        </p>
        <p>
            This version also tentatively fixes a bug where, for Document Instances 
	    with a Document Type Name of "html", but with
            an incorrect Formal Public Identifier, the Validator would fall back
            to HTML 4.01 Transitional and, if no other errors were found,
            silently ignore the erroneous FPI.

	    Major internal restructuring. The code has undergone significant
            refactoring with many benefits. It is more readable and easier to
            understand, much more robust, much improved security, more modular,
            and performance should be significantly better. There is tentative
            support for running under mod_perl (leading to even greater
            performance enhancements) and memory consumption should be much
            improved.
	  </li>
          <li>
            Many new document types are supported and support for some
            existing document types has been improved. Notable changes
