+    <td class="content">
+      The PDE Target Editor now supports to specify a range as version of a <code>unit</code> or to omit the specification of a version entirely in <code>InstallableUnit</code> locations.
+      Without an explicit version the value <code>0.0.0</code> is used by default, which resolves to the latest version available.
+      All of the following variants to specify a version in the <code>Source</code> tab of the Target Editor are now possible:
+      <p><img src="images/target-version-ranges-source.png" alt="Version ranges and omitted version in an IU target location"/></p>
+      It is also possible to define these advance versions specifications through the UI of the Target Editor.
+      After clicking the <code>Edit</code> button for a location, you can specify a version range for a selected unit directly in the table.
+      Entering <code>latest</code> is equivalent to <code>0.0.0</code> and always resolves to the latest version of that unit.
