dub says it uses SemVer, though, and SemVer changed. So we
don't have a choice of whether to be consistent or
inconsistent, but about what to be inconsistent with: the new
or the old. Over time, and especially since dub.pm points to
semver.org to justify the version requirements it has, the
inconsistency with the new will cause more problems.

And, "no longer requires" is putting it gently. semver.org
actually says:

Q: Is “v1.2.3” a semantic version?
A: No, “v1.2.3” is not a semantic version.

Now, compare this with the 1.0.0 doc, which



It doesn't mention 'v' at all. It just talks about 1.2.3
versions. The only 'v' is in the URL. Also the URL for the
*new* version of semver is


Also, after the Q&A that I quoted before, it says:

What's the problem again?
