• migration note:
  • to_dict() and to_json() now accept a verbose_level parameter and always return a usable text-view dict. When the original view is 'tree', they default to verbose_level=2 for full detail. The old view_override parameter is removed. To get the previous results, you will need to pass the explicit verbose_level to to_json and to_dict if you are using the tree view.
