+      <p>Non-Transparent Bridges allow creation of memory windows between
+	different systems, using the regular PCIe links of CPUs as a
+	transport.  During the last quarter, the NTB subsystem gained a
+	significant set of improvements and fixes:</p>
+
+      <ul>
+	<li>The code was modularized, utilizing &os;'s NewBus interfaces
+	  to allow support for different hardware types with different
+	  drivers, support for multiple NTB instances in a system,
+	  using the <tt>ntb_transport</tt> module for consumers other
+	  than <tt>if_ntb</tt>, etc.</li>
+
+	<li>Support for splitting NTB resources between different
+	  applications was added, such as doing direct access to some range
+	  of remote memory and to a virtual network interface between nodes
+	  at the same time, etc.</li>
+
+	<li>The virtual network interface driver gained support for many
+	  modern features, such as multiple queues, new locking, etc.</li>
+
+	<li>NTB performance and SMP scalability was improved.</li>
+
+	<li>Multiple workarounds for hardware issues were added.</li>
+      </ul>
+
+      <p>The code is committed to the &os; head, stable/11 and stable/10
+	branches.</p>
