    Contains information about the current status of a webhook.

    Objects of this class are comparable in terms of equality. Two objects of this class are
    considered equal, if their :attr:`url`, :attr:`has_custom_certificate`,
    :attr:`pending_update_count`, :attr:`ip_address`, :attr:`last_error_date`,
    :attr:`last_error_message`, :attr:`max_connections`, :attr:`allowed_updates` and
    :attr:`last_synchronization_error_date` are equal.

    .. versionchanged:: 20.0
       :attr:`last_synchronization_error_date` is considered as well when comparing objects of
       this type in terms of equality.

    Args:
        url (:obj:`str`): Webhook URL, may be empty if webhook is not set up.
        has_custom_certificate (:obj:`bool`): :obj:`True`, if a custom certificate was provided for
            webhook certificate checks.
        pending_update_count (:obj:`int`): Number of updates awaiting delivery.
        ip_address (:obj:`str`, optional): Currently used webhook IP address.
        last_error_date (:class:`datetime.datetime`): Optional. Datetime for the most recent

        max_connections (:obj:`int`, optional): Maximum allowed number of simultaneous HTTPS
            connections to the webhook for update delivery.
        allowed_updates (Sequence[:obj:`str`], optional): A list of update types the bot is
