I'm not sure I understand the git history leading to tag v0.20.4, but it seems to include the commit that bumped helpers.CurrentHugoVersion to 0.21-DEV
That is also reflected in the released source package for that version.

On the other hand, the binary artifacts I tried for that release declare a version v0.20.4, which puzzles me. Am I overlooking a subtlety of goreleaser ?
If so, how exactly are we supposed to build hugo so that hugo version displays the right number ?

Thanks
