      # What are we automatically merging?
      # MINOR and PATCH updates
      # Development dependencies
      # Indirect dependencies

      # ----------------------
      # ------ IMPORTANT ------
      # Unfortunately dependabot core does not support knowing if an indirect dependency is from production or development
      # [https://github.com/dependabot/fetch-metadata/issues/43#issuecomment-878173130]
      # I am taking the risk to automatically update indirect dependencies of production dependencies.
      # Ts-auto-mock will not be published automatically because of this.
      # Before releasing a new version of ts-auto-mock the production dependencies need to be reviewed.
