- New 'domid_policy', allowing domain-ids to be randomly chosen.
- Option to preserve domain-id across migrate or save+restore.
- Support in kdd for initial KD protocol handshake for Win 7, 8 and 10 (64 bit).
+ - Tech preview support for Control-flow Execution Technology, with Xen using
+ Supervisor Shadow Stacks for its own protection.

+### Changed
+ - The CPUID data seen by a guest on boot is now moved in the migration
+ stream. A guest migrating between non-identical hardware will now no
+ longer observe details such as Family/Model/Stepping, Cache, etc changing.
+ An administrator still needs to take care to ensure the features visible to
+ the guest at boot are compatible with anywhere it might migrate.
