Xen Project 4.10 Acknowledgements
Note that the acknowledgements have been created based on 4.10.0-rc7, which are provisional. The table assumes we release on December 13th, 2017 based on 4.10.0-rc7 including some security fixes that are currently under embargo. These fixes are not included in these statistics.
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.
