Migration Instructions

• dhtproto.client.request.Get

  The notification union for Get requests now includes an additional field:
  timed_out. Get notifiers should be updated to handle this field (a simple
  case timed_out: break; is sufficient, if your application is not using Get
  timeouts).

• dhtproto.client.DhtClient : Neo, dhtproto.client.request.Mirror

  The API of the Mirror request has changed such that it is no longer possible
  to start a Mirror request which does not stream live updates from the node to
  the client. The Settings.live_updates flag has been removed, along with the
  finished notification. Now, the only way for a Mirror request to end is if
  the user stops it (or the channel being mirrorred is removed).

New Features

• dhtproto.client.DhtClient : Neo, dhtproto.client.request.GetAll

  The new GetAll request provides a way to fetch a snapshot of all records in a
  channel. If the request is interrupted (e.g. by a connection error), it is
  automatically restarted and continues where it left off.

• dhtproto.client.DhtClient : Neo

  The get method now accepts an optional argument of type Neo.Get.Timeout,
  specifying a milliseconds timeout value. If the request has not completed
  before the timeout expires, the request is aborted and the notifier called
  with the timed_out notification.

• dhtproto.client.request.Mirror

  A new notification type -- updates_lost -- has been added. The node sends
  this notification to the client when its internal queue of updates to be sent
  overflows. This means that at least one update has not been sent to the
  mirroring client and indicates that there's a disparity between the rate at
  which updates are being made to the mirrored channel and the rate at which the
  Mirror request is able to inform the client of these updates.
