== Overview == |
|||
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 4.8 with Xen 4.9. 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 4.9 Hypervisor Total. |

Revision as of 10:14, 5 June 2017
Note that the acknowledgements have been created based on 4.9.0-rc7, which was the final RC for Xen 4.9.0. If there is another release candidate, data needs to be updated.
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 4.8 with Xen 4.9. 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 4.9 Hypervisor Total.
