Things are changing with this next release. The next two major releases will be: 10.x (or 10.0.x using historical nomenclature - 1000xx) 11.x (or 11.0.x using historical nomenclature - 1100xx) For prior releases the major versions are: 9.2.x 9.3.x 9.4.x 9.5.x 9.6.x If you want to consider the 9 to be "major" and the .[2-6] to be minor for mechanical purposes that's fine but the change from 9.5 to 9.6 is a major change with backward incompatibilities - which a minor change doesn't allow. In the new setup the thing you call "minor" will always remain at zero in order to eventually mitigate the need to have this kind of discussion. Since it is always going to be "0" we simply omit printing it. David J.
