 Dockerfile was changed. The execution of workflows of unchanged Dockerfiles will not continue and just return success.
 See `scripts/ci/docker_upgrade.sh`.
 
 If the version check was successful, the docker image will be built using the Dockerfile located in
 `scripts/docker/buildpack-deps/Dockerfile.*`.

 These scripts `scripts/ci/build.sh` and `scripts/ci/build_ossfuzz.sh` are also used by CircleCI, see `.circleci/config.yml`.
 
 If the tests passed successfully, the docker image will get tagged by the version defined within the corresponding `Dockerfile`.
