From Xen
(Copied 4.9 tables (removing 4.9 stuff in next revision))
 
(Data based on Xen 4.10 RC3)
Line 1: Line 1:
Note that the acknowledgements have been created based on 4.9.0-rc9, which is expected to be the final RC for Xen 4.9.0 (with the exception of some security fixes under embargo). If there is another release candidate, data needs to be updated.

Note that the acknowledgements have been created based on 4.10.0-rc3, which are provisional. The table assumes we release on December 2nd, 2017

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 17:06, 6 November 2017

Note that the acknowledgements have been created based on 4.10.0-rc3, which are provisional. The table assumes we release on December 2nd, 2017

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 4.9 with Xen 4.10. 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 4.10 Hypervisor Total.
