Release notes
We are deprecating the CI based GitLab managed apps as they are known today. The CI template will be removed from GitLab in version 15.0. At the same time, we are releasing a project template that provides the same functionality and allows our users to extend the setup with other applications and own the applications fully. The cluster management project integration remains unchanged.
