Requirements

gitlab_awesome_release

You can install using gem

gem install gitlab_awesome_release

You need a token because Gitlab doesn't accept more than a certain number of requests per minute (should be 10).

Generate the CHANGELOG.md

export GITLAB_API_PRIVATE_TOKEN="YOUR GITLAB PRIVATE TOKEN"
export GITLAB_API_ENDPOINT="http://gitlab.com/api/v4"
export GITLAB_PROJECT_NAME="Remmina/Remmina"
gitlab_awesome_release create_latest_note --filename=CHANGELOG.1.4.10.md

Than use the newly created note to update the file CHANGELOG.md

Commit the new CHANGELOG.md

The CHANGELOG.md should be committed only during a new release.
