Which one is correct when referring to a feature that has been implemented in a version x.y.z and is still available until the latest versions?

I have found this link about "Version x.y.z or later"

But I have also seen "Deselect text. Since 5.1" being used here

Which one would be correct or at least the most common?

    I've found the 'Deselect text. Since 5.1' entry, but can't decide immediately what the 5.1 is a version of. I find this unusual (I'd expect 'Since version 5.1' anyway), and I'd think that '[version 5.1 and later]' would be far more common. But 'which one is correct?' suggests strongly that one is forbidden. I doubt that there is a rule being broken here, unless we invoke 'always use the most idiomatic choice'. Feb 8, 2023 at 12:20
  • @EdwinAshworth, thanks for your answer. So you believe that "Version 5.1 and later" would be the most idiomatic choice?

    There are some expressions where it's not clear if version 5.1 is included ("following version 5.1", "after version 5.1") but both of these seem inclusive.

  • What do you mean by until in still available until the latest versions? Do you mean that the feature is still available in the current version? Feb 9, 2023 at 2:54

Both are correct and commonly used. So you can safely use them. Ngram clearly shows that the usages of these two formulas are intertwined:

If it helps, version x or later was most common in the 90s.


The former answer is about referring to version numbers in an article about a piece of software. The latter example comes from a table in an API reference and refers to the version of the library being documented.

In the latter case, a more abbreviated style is appropriate. The readers (Qt programmers) can be expected to tell that it is a version number, that it is a version of Qt more specifically, and that it refers to an API not implemented in prior versions of the software.
