I was agreeing with your sentiment. Upgrade doesn't mean what the guy thinks it should, per apt, one of the most widely-used package managers on the planet.

That said, I do disagree with you now. The language used to describe...uhh..."increasing" minor vs major versions is exactly the kind of thing package-manager-maintainers would get to decide on. What do you think, we're going to have a congress of linguists to determine command line flag names?
