There doesn't appear to be any versioning scheme or any way to indicate a version of the code except by commit number. A version scheme would offer identifiers associated to high-level feature adds or bug fixed that low-level commit numbers don't quite capture. For starters, I'd suggest semantic versioning as a basic scheme unless there's reason to want a more involved versioning scheme: http://semver.org.
