Follow-up from the 1.15 release

Issues with the release that need to be fixed:

• The upload_to_repo job was not able to trigger any gitlab runner after the migration in issue 1170. The job has too many tags. Removing stork-repo or aws would solve the impasse.
• The release notes are currently folded at 73 characters. This includes folding changelog entryes. There seems to be a gentleman's agreement that changelog entries should be capped at 80 characters. This makes the changelog in the release notes less readable than it could be. Look at the 1.14 release notes for example. This has been manually fixed for 1.15, but extending the folding to 80 would be good. A lint step in CI to make sure this rule is respected for changelog entries wouldn't hurt either.
