Git flow release branches and tags - with or without "v" prefix

Question

Well, basically it is a matter of preference, but I prefer the version with the v, as Semver does it that way and I try to follow that specification as close as possible to get a sane versioning.

It also makes filtering for those Tags easier, as you can press v and then the TAB-key for autocompletion: This will list all the tags (and maybe a few branches), whereas there are several digits a tag could start with.

Edit: In 2019, Semver added a section to their FAQ, clarifying that the "v" prefix is "a common way to indicate a version number" (see "Is “v1.2.3” a semantic version?").

Since v stands for version, tags are generally named vX.Y.Z, with X.Y.Z following Semantic Versioning 2.0.0.

This allows for branches X.Y.Z to co-exist with those tags, without having to deal with error message like "fatal: Ambiguous object name" (as in "Ambiguous Names with GIT?").

Note that the tags for Git itself have recently been "adapted" for a surprising reason: see "Code version change “rules”".

Is “v1.2.3” a semantic version? No, “v1.2.3” is not a semantic version. However, prefixing a semantic version with a “v” is a common way (in English) to indicate it is a version number. Abbreviating “version” as “v” is often seen with version control. Example: git tag v1.2.3 -m "Release version 1.2.3", in which case “v1.2.3” is a tag name and the semantic version is “1.2.3”.
