- The updated Open vSwitch switch to version 1.4.2 with improvements of stability and performance
- Support of Integrated StorageLink (iSL) technology for arrays of EMC VNX
- Tekhnlogiya GPU Pass-through (probros video cards in guest OS): support to 4 GPU per host server
- Improvements for integration into third-party solutions: baynding for XenAPI for language C, the Workload Balancing (WLB) expansions and the general improvements
- Support of the hypervisor monitoring equipment (vhostmd) allowing SAP applications to work in the XCP virtual machine
