One job to check outdated composer packages can also be helpful:

check-outdated:
  image: composer
  stage: test
  allow_failure: true
  script:
  - composer install --no-ansi --no-interaction --no-dev --no-progress --no-scripts
  - composer outdated -D -m --strict

Running that job (and other test jobs) scheduled and skip the deployment jobs with

ter-upload:
  except:
    - schedules

lets you monitor the version state of your projects.
