@cfc4n Had to revert this commit in release-3.3 branch because our release script was overwriting the version name string from this go.mod file.

OK, I see ,thank you.Do I need to do it？

[gyuho]

@cfc4n Yeah that would be great if you can help... Or do you still need module files? I haven't figured out how go module files were affecting version strings...

[cfc4n]

I think , most user need module files who troubled by this problem. ref #12068

Can you give some message about release errors?
