They chose “version” because they are just that, versions. Improvements over the original design that benefit from new insights and technological improvements. We’re lucky they had the foresight to include a version number in the spec.

No they aren't. A higher version of UUID isn't "newer and better", like the word "version" implies. It's just different. It's like they called a car "vehicle version 1" and a motorbike "vehicle version 2". The common use of "version" in the software world would mean that a motorbike is a newer and hopefully improved version of a car, which is not the case.

The talking pumpkin is 100% right that they should have used "type" or "mode" or "scheme" or something instead.

"Version" is definitely used commonly to describe two different ... versions of the same thing, without implying that one is better than the other or supercedes it. There are two versions of the PS5, one with and one without a disk drive. There are many different versions of Windows, like Home or Enterprise. You can get hardcover or paperback versions of many books. Etc. Etc.

In normal English, when not using a number, sure! But in software, with numbers versions it almost universally means chronological releases of something.

There are many different versions of Windows, like Home or Enterprise. You can get hardcover or paperback versions of many books.

Great examples! Those are both called "editions", not versions. Thanks for proving my point 😄

Version 5 of a software, device, vehicle or such isn't necessarily better than version 4, and no official definition of the word "version" require this, either. If I may make another anology: You may pick one of 5 different versions of an outfit to wear, and even though they were labeled in the order they were made, from 1 to 5, none are inherently, objectively better than any other. In the case of UUIDs there are versions that are meant to supercede others, but also simply alternatives for different use-cases. Anyone with access to some up-to-date information can learn what each version's purpose is.

Yep, I can attest to that! I used to play Minesweeper Adventure version. Then Microsoft decided to do a complete rewrite and literally ruined the game. It was way slower and way buggier, and on top of that they also lost all my progress. So, well done Microsoft - now instead of seeing more ads (which was undoubtedly why they did the rewrite) I now don't see ANY ads (because the game is just horrible now and not worth playing anymore, even if it didn't have any ads!).
