+    <h3>Querying of External Projects</h3>
+    <p class="date">March 30, 2026</p>
+    <p>
+        We added a new tool for querying external projects that are
+        known to Serena: From the current project, use Serena's tools on another project to retrieve information.
+        This is useful in situations where the current project builds on or is otherwise related
+        to other projects.
+    </p>
+    <p>
+        Find out more about this feature in our <a href="https://oraios.github.io/serena/02-usage/040_workflow.html#reading-from-external-projects">documentation</a>.
