As we have made significant changes to the xen source tree structure, we will count acknowledgements in line with [http://lists.xenproject.org/archives/html/xen-devel/2015-10/msg01063.html RFC Xen 4.6 Acknowledgements]. |

Overview
As we have made significant changes to the xen source tree structure, we will count acknowledgements in line with RFC Xen 4.6 Acknowledgements.
The following table compares Xen 4.6 with Xen 4.7. We also cover changes to Xen only components in Linux, FreeBSD, NetBSD and QEMU in the "Drivers and Devices" column, which are primarily made by Xen Project developers. Note that the number is not part of the 4.7 Hypervisor Total.
Attribute | 4.6 Hypervisor Total [ 1 ] | 4.7 Hypervisor Total [ 2 ] | 4.7 Hypervisor Core[ 3 ] | 4.7 Hypervisor Other [ 4 ] | Drivers and Devices (other projects)[ 5 ] |

The following breakdown shows how the number of changesets per categories listed above have evolved between the 4.6 and 4.7 release cycles
