+        </summary>
+        <description>
+          This feature, introduced in QEMU 4.2, is a more modern alternative
+          to virtio-9p, which is exposed through the same
+          <code>&lt;filesystem/&gt;</code> element.

+        <description>
+          After renewing TLS certificates, it was usually necessary to restart
+          libvirtd for the new ones to be loaded: now the same result can be
+          obtained without restarting the daemon by using <code>virt-admin
+          server-update-tls</code>.

+        <description>
+          This check was introduced to prevent same-host migration, but did
+          not work as expected when multiple libvirtd instances were running
+          on the same host but in different containers. With this release, the
+          host UUID (which should be unique to the container) is checked
+          instead.

+        <description>
+          Instead of using a single even loop to process communication with
+          the QEMU monitor and guest agent, create a separate one for each VM.
+          This helps with scalability and prevents scenarios where a single
+          malfunctioning VM could affect all those running on the same host.
