+<h1>Xen Hypervisor 4.2 Download</h1>
+ <p> Welcome to the Xen 4.2 download page!
+ <p></p>
+
+ <p> The Xen 4.2 release contains a number of important new features and updates including:</p>
+
+ <p>The release incorporates many new features and improvements to existing features. There are improvements
+ across the board including to Security, Scalability, Performance and Documentation.<ul>
+
+ <li><strong>XL is now the default toolstack</strong>: Significant effort has gone in to the XL
+ tool toolstack in this release and it is now feature complete and robust enough that we have made
+ it the default. This toolstack can now replace xend in the majority of deployments,
+ see <a href="http://wiki.xen.org/wiki/XL_vs_Xend_Feature_Comparison">XL vs Xend Feature Comparison</a>.
+ As well as improving XL the underlying libxl library has been significantly improved and supports
+ the majority of the most common toolstack features. In addition the API has been declared stable
+ which should make it even easier for external toolstack such as <a hfref="http://libvirt.org/">libvirt</a>
+ and <a href="http://www.xen.org/products/cloudxen.html">XCP's</a> xapi to make full use of this functionality
+ in the future.</li>
+
+ <li><strong>Large Systems</strong>: Following on from the improvements made in 4.1 Xen now supports even
+ larger systems, with up to 4095 host CPUs and up to 512 guest CPUs. In addition toolstack feature like the
+ ability to automatically create a CPUPOOL per NUMA node and more intelligent placement of guest VCPUs on
+ NUMA nodes have further improved the Xen experience on large systems. Other new features, such as multiple
+ PCI segment support have also made a positive impact on such systems.</li>
+
+ <li><strong>Improved security</strong>: The XSM/Flask subsystem has seen several enhancements, including
+ improved support for disaggregated systems and a rewritten example policy which is clearer and simpler to
+ modify to suit local requirements.</li>
+
+ <li><strong>Documentation</strong>: The Xen documentation has been much improved, both the
+ <a href="http:/xenbits.xen.org/docs/4.2-testing/">in-tree documentation and the <a href="http://wiki.xen.org/wiki">wiki</a>.
+ This is in no small part down to the success of the <a href="http://wiki.xen.org/wiki/Xen_Document_Days">Xen Document Days</a> so
+ thanks to all who have taken part.</li>
+
+ </ul></p>
