+    <li><strong>New UI, and faster and more configurable implementation for PCA, Neighbour-Joining and UPGMA Trees</strong><br>
+      Menu entries for calculating PCA and different types of tree have
+      been replaced by a single <em>Calculations</em> dialog box. The
+      underlying implementation for the PCA and tree calculations have been
+      made faster and more memory efficient. A new framework has also been
+      created for the score models used to calculate distances between
+      sequences. This framework allows import of substitution matrices in
+      NCBI and AAIndex format, and custom score models to be created via a
+      groovy script.</li>
