There's no minor and major. All releases are equivalent but the first number is bumper when the second becomes large enough, which happens every 2-3 years.
In fairness, that is a weird versioning scheme, and I really do wish that Linux either switched to full semver (in which case it'd be version 2.9000.0 or so by now) or just drop the leading digit and go full build number kinda like NT does. But as cousin comments note, not my project not my call:)
