• Go to releases, an action will generate a draft release with docs + attached QVF
• Make any updates, then submit the release

Common issues:

• Version number missing or incorrect (./VERSION file needs updating)
• After merging, draft release doesn't update - this is usually because
  the action failed due to an old draft release with the same name.
  Delete the draft release, and re-run the action.
