Further comments

We had set the flag prerelease: true in the atlascli goreleaser file as a precaution. Now that we are ready to release v1.0.0 we have to set prerelease to auto

See goreleaser doc

  # If set to auto, will mark the release as not ready for production
  # in case there is an indicator for this in the tag e.g. v1.0.0-rc1
  # If set to true, will mark the release as not ready for production.
  # Default is false.
  prerelease: auto
