  <summary>Recommended update for obs-service-docker_label_helper</summary>
  <description>This update for obs-service-docker_label_helper fixes the following issues:

- Support new syntax which makes Dockerfiles compatible with plain Docker/podman build.
  The new syntax uses  entry/exit point to determine whether labels should be expanded.
  Doing so makes the Dockerfile compatible with standard `docker build` and `podman build` command.
  (bsc#1193429)
- Retain compatibility with old syntax. Update documentation
- Improve summary, description and README.md a bit
- Improve regexp instead of having two as proposed by Fabian Vogt
