    - This release dynamically loads the JavaScript interpreter and can
      cope with it not being available. In this case, polkit authorization
      rules are not processed and the defaults for an action - as defined
      in its .policy file - are used for authorization decisions.
    - Add new meta-package, polkit-js-engine, that pulls in the required
      JavaScript bits to make polkit authorization rules work. The default
      install - not the minimal install - should include this package
