Looks good.

@mdelapenya, the ci build is still using go 1.15.8, and not the go 1.16.4 version from the .go-version file; do you know why?

The run_with_go_ver script is not used in any Make goal apart from the release-manager-release one. I think that's the root cause.

On the other hand, I can see that gimme is used to install Go. In Beats, the team is using @andrewkroh's gvm tool. Is that on purpose?

UPDATE: The PR is there! #346

@blakerouse, Should we add any notes about the min macos version needed with the new crossbuild image (10.14)?

@michel-laterman Adding a note would be helpful.
