v0.31.04 (WIP)
--------------



v0.31.03
--------

* Bootstrap changed to accept empty bootstrap list, or a list containing only
  joining node's details.  These cause the node to create a new network.
* Most Node methods now call back with kNotJoined if node not joined.
* If node not joined, it now doesn't responds to incoming requests.
* Significant rework of iterative lookup process.
* Implemented Downlist functionality.
* Implemented StoreRefresh and DeleteRefresh functionality.
* FindValue now returns kSuccess only if the value was found.  If an alternative
  store holder was found, returns kFoundAlternativeStoreHolder.  If closest
  contacts are returned, kFailedToFindValue is returned.  These codes are >= 0.
  Any other return code will be negative and will indicate failure.
* Own contact is now considered during lookups.  This means that it can be
  returned by FindNodes, FindValue, GetContact and that Store, Delete and Update
  will operate on the node initiating the request.
* Own contact can also be returned as the "needs_cache_copy" Contact.
* FindValue and FindNodes can look for > k contacts if required.
* Created OrderedContacts typedef (set of Contacts ordered by closeness to a
  target ID).
* Added methods for constructing an OrderedContacts instance.
* Devolved some of the signature validation from DataStore to Service.
* Changed Transport MessageHandler to handle uninitialised messages.
* Changed Kademlia MessageHandler to handle uninitialised messages.
* Added error logging to NodeImpl, SenderTask, and Kad Service.
* Switched off reuse_address for TCP connections.
* Removed DataStore for client-only nodes.
* Routing Table now updates contacts' details if they change.
* Better handling of second node joining existing network of one.
* Various work on NodeContainer.
* Various test fixes.
