Note that the Acknowledgements have been created based on 4.8.0-rc8, which was the final RC for Xen 4.8.0 |
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 4.7 with Xen 4.8. 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 4.8 Hypervisor Total.

Breakdown by Individual
Note that the table below does not cover contributions to Linux, NetBSD, FreeBSD, QEMU, libvirt and other related projects. It lists contributors to mini-os (formerly part of xen.git), osstest (our test code and test cases), raisin (a deployment and test tool) and livepatch-build-tools (tools to builld livepatch payloads).
