      Kwargs:
          refresh (bool): Refresh package metadata. Default ``True``
          saltenv (str): The salt environment. Default ``base``

      .. code-block:: bash
  
          salt '*' pkg.upgrade_available <package name>
      '''
      saltenv = kwargs.get('saltenv', 'base')
      # Refresh before looking for the latest version available,
      # same default as latest_version
      refresh = salt.utils.data.is_true(kwargs.get('refresh', True))
  
      # if latest_version returns blank, the latest version is already installed or
      # their is no package definition. This is a salt standard which could be improved.
