`-version` only reports `main`

Topic says it all, really. The output of version is not terribly helpful, it could be improved by adding a version and optionally a build time/date.

Hi. Are you referring to the Docker image, the released binaries, or both ?

[Gaibhne]

Oh, sorry, I didn't realize there was a distinction. The latest Docker image is where I see that behaviour.
