/*
* Viona Interface Version
*
* Like bhyve, viona exposes Private interfaces which are nonetheless consumed
* by out-of-gate consumers. While those consumers assume all risk of breakage
* incurred by subsequent changes, it would be nice to equip them to potentially
* detect (and handle) those modifications.
*
* There are no established criteria for the magnitude of change which requires
* this version to be incremented, and maintenance of it is considered a
* best-effort activity. Nothing is to be inferred about the magnitude of a
* change when the version is modified. It follows no rules like semver.
*
