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].
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].


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.
The following table compares Xen 4.6 with Xen 4.7.

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.
