     <summary>VirtualBox Extension Pack adds Support for USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards.</summary>
     <description>Oracle VM VirtualBox is a general-purpose full virtualizer for hardware. Targeted at server, desktop and embedded use, Oracle VM VirtualBox is now the only professional-quality virtualization solution that is also Open Source Software.
 
       VirtualBox Extension Pack adds Support for USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards.
 
       https://www.virtualbox.org/manual/ch01.html#intro-installing
+      
+      [Deprecated]: This VirtualBox.ExtensionPack package has been obsoleted in favor of having both VirtualBox and the extension pack installed via the same package - the "virtualbox" package (which should prevent the version discrepancies going forward).  The virtualbox package now installs the extension pack by default (unless you specify an argument when installing the package to NOT install the extension pack).  Since this is installed in the virtualbox package, this VirtualBox.ExtensionPack package will no longer be maintained/updated.
