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 4.11 with Xen 4.12. 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 4.12 Hypervisor Total.

<b>Note:</b> The data below shows a reduction in public code review activity, as well as development velocity. This figure is substantially skewed by a number of large and complex security related code series that were developed in private under security embargoes. In other words, the reduction signifies that we are doing fewer public reviews to satisfy requirements that allow project members to fix issues under security embargoes. In addition, we ported many of these changes - including code that enabled these series - to older releases of Xen to uphold our maintenance and security guarantees.
