+    <!-- HEADLINE: Introduction -->
+
+    <h3 class="title" id="introduction">Introduction</h3>
+    <p>There has been a significant amount of work done since V1.9.3.</p>
+
+    <!-- HEADLINE: New toolbox features and changes-->
+
+    <h3 class="title" id="newFeatures">New toolbox features and changes</h3>
+    <p>The highlights are:</p>
+    <ul>
+      <li><p>A new Graphical Programming interface for the construction of
+          signal processing pipelines (LTPDAworkbench)</p></li>
+      <li><p>New data whitening methods are included, <b>ao/whiten1D</b> and
+          <b>ao/whiten2D</b>.</p></li>
+      <li>
+        <p>Most methods of the AO class should now support multiple outputs,
+          in addition to the vector output. For example, the following are supported:</p>
+        <ul>
+          <li><p><b>a = lpsd(b1,b2,b3)</b></p></li>
+          <li><p><b>[a1,a2,a3] = lpsd(b1,b2,b3)</b></p></li>
+        </ul>
+      </li>
+      <li>
+        <p>Model fitting tools:</p>
+        <ul>
+          <li><p><b>curvefit</b> for doing non-linear least-squares,
+              now including weights</p></li>
+          <li><p><b>lscov</b> for doing linear least-squares fitting</p></li>
+          <li><p><b>straightLineFit</b> is a wrapper of <b>lscov</b> for
+              fitting data with a straight-line</p></li>
+        </ul>
+      </li>
+      <li><p>Operators, +-.*./*/, all conform to more standard MATLAB type 
+          behaviour. For example, adding a single AO to a vector of AOs results
+          in a vector of AOs where the single AO is added to each element of the vector.</p></li>
+      <li><p>Digital filtering with IIR filters now has two possible ways of
+          applying a bank of filters. By specifying the &lsquo;<b>bank</b>&rsquo;
+          parameter, the filters will be applied as a &lsquo;<b>serial</b>&rsquo;
+          bank or a &lsquo;<b>parallel</b>&rsquo; bank.</p></li>
+      <li><p>Two new noise-generators are included, <b>noisegen1D</b> and
+          <b>noisegen2D</b> (which can produce correlated data streams).</p></li>
+      <li><p>AOs can now be built from a set of built-in models. Users can also
+          write their own models and point LTPDA to a directory (or more than one)
+          containing those model files.</p></li>
+      <li><p>The user preferences of LTPDA are now controlled via a graphical
+          user interface. To adjust the user preferences, run <b>LTPDAprefs</b>.</p></li>
+      <li><p>Two new transfer function representations are present as user classes
+          of this version of the toolbox. The class <b>parfrac</b> allows the
+          user to build transfer function models that are a series of partial
+          fractions; the class <b>rational</b> allows the user to build a
+          transfer function as a rational polynomial in s. Some converters also
+          exist to go between these and the existing transfer function models,
+          <b>pzmodel</b> (pole/zero models), <b>miir</b> (IIR filters) and
+          <b>ssm</b> (state-space models).</p></li>
+      <li><p>A new method, <b>ao/heterodyne</b>, to heterodyne data at a given
+          frequency.</p></li>
+      <li><p>All transfer function representations and digital filters now can 
+          be assigned input and output units. This means that units are now
+          propagated through fully through any analysis.</p></li>
+      <li><p>A new <b>rebuild</b> method to rebuild objects from their
+          self-contained history trees.</p></li>
+      <li>
+        <p>New graphical user interfaces</p>
+        <ul>
+          <li><p>modelViewer - a viewer for the built-in ao and ssm models</p></li>
+          <li><p>constructor - a helper for writing object constructors (rewritten)</p></li>
+        </ul>
+      </li>
+      <li><p>New convenient AO methods to apply gain and to add an offset to
+
+          data (<b>scale, offset</b>).</p></li>
+      <li><p>Transfer function estimators now return error terms in the
+          <b>procinfo</b> field of the result <b>ao</b>.</p></li>
+      <li><p>Units are not automatically simplified. Instead the user can now 
+          do that on demand with the <b>simplifyYunits</b> method. There are
+          also methods to convert between Hz and s: <b>HzToS</b> and <b>sToHz</b>.</p></li>
+      <li><p>Digital IIR filters are now initialised to a state based on the
+          input data. This should reduce start-up transients.</p></li>
+      <li><p>Data in AOs can be converted from one type to another using the
+          new <b>ao/convert</b> method.</p></li>
+      <li><p>Pole/zero models (<b>pzmodel</b>) now support a delay parameter.</p></li>
+    </ul>
