I keep pretty up to date with this stuff but I recently read a line on GitHub that said “this software requires macOS 15 or greater”. And I had no idea if that was the current version, a really old version, or the next beta. When I see a version number, what I really care about is how new/old it is, not how many releases it’s been since the first version. Which is why one of my most common Google searches is “when did <software> <version number> release”
