None, at least as far as my code is concerned. It's just that I've
already added a new libxc helper function with assorted HV-side code and
just assumed that __XEN_LATEST_INTERFACE_VERSION__ had been bumped to
0x00040700, so some of my own code wasn't being compiled as it depended
on that value. Of course, there's nothing wrong with the current
approach, I was just curious if bumps happen as soon as a new version is
out or only when the interface changes.


Thanks,
