-      <p><b>&os;&nbsp;9.0</b>, brings many new features
-	and performance enhancements with a special focus on desktop
-	support and security features.</p>
+      <p><b>&os;&nbsp;10.X</b> introduced many new features
+	and replaces many legacy tools with updated versions.</p>
 
       <ul>
+	<li><b>bhyve</b>:
+	  A new BSD licensed, legacy-free hypervisor has been imported
+	  to the &os; base system.  It is currently able to run all
+	  supported versions of &os;, and with the help of the
+	  grub-bhyve port, OpenBSD and Linux.</li>
+
+	<li><b>KMS And New drm2 Video Drivers</b>:
+	  The new drm2 driver provides support for AMD GPUs up to the
+	  Radeon HD 6000 series and provides partial support for
+	  the Radeon HD 7000 family.  &os; now also supports
+	  Kernel Mode Setting for AMD and Intel GPUs.</li>
+
+	<li><b>Capsicum Enabled By Default</b>:
+	  Capsicum has been enabled in the kernel by default, allowing
+	  sandboxing of several programs that work within the
+	  "capabilities mode", such as:
+	  <ul>
+	    <li>tcpdump</li>

+	    <li>hast</li>
+	    <li>rwhod</li>
+	    <li>kdump</li>
+	  </ul>
+	</li>
+
+	<li><b>New Binary Packaging System</b>:
+	  &os; now uses pkg, a vastly improved package management
+	  system that supports multiple repositories, signed packages,
+	  and safe upgrades.  The improved system is combined with
+	  more frequent official package builds for all supported
+	  platforms and a new stable branch of the ports tree for
+	  better long term support.</li>
+
+	<li><b>Unmapped I/O</b>:
+	  The newly implemented concept of unmapped VMIO buffers
+	  eliminates the need to perform costly TLB shootdowns for
+	  buffer creation and reuse, reducing system CPU time by up to
+	  25-30% on large SMP machines under heavy I/O load.</li>

+	and performance enhancements with a special focus on desktop
+	support and security.</p>
+
+      <ul>
+	<li><b>OpenZFS</b>:
+	  &os; 9.2 includes OpenZFS v5000 (Feature Flags), including
+	  the feature flags:
+	  <ul>
+	    <li>async_destroy</li>
+	    <li>empty_bpobj</li>
+	    <li>lz4_compress</li>
+	  </ul>

+	  background, make snapshots consume less disk space, and
