* ``FlowLogic`` communication has been extensively rewritten to use functions on ``FlowSession`` as the base for communication
|
||||
between nodes.
|
||||
|
||||
* Calls to ``send()``, ``receive()`` and ``sendAndReceive()`` on FlowLogic should be replaced with calls
|
||||
to the function of the same name on ``FlowSession``. Note that the replacement functions do not take in a destination
|
||||
parameter, as this is defined in the session.
|
||||
* Initiated flows now take in a ``FlowSession`` instead of ``Party`` in their constructor. If you need to access the
|
||||
counterparty identity, it is in the ``counterparty`` property of the flow session.
|
||||
|
||||
|
||||
* Added X509EdDSAEngine to intercept and rewrite EdDSA public keys wrapped in X509Key instances. This corrects an issue
|
||||
with verifying certificate paths loaded from a Java Keystore where they contain EdDSA keys.
|
||||
|
||||
* Confidential identities are now complete:
|
||||
|
||||
* The identity negotiation flow is now called ``SwapIdentitiesFlow``, renamed from ``TransactionKeyFlow``.
|
||||
* generateSpend() now creates a new confidential identity for the change address rather than using the identity of the
|

input state owner.

the first identity still plays a special role of main node identity.

``getNodesWithService``, ``getPeersWithService``, ``getRecommended``, ``getNodesByAdvertisedServiceIdentityKey``, ``getAnyNotary``,

``NetworkMapCache::notaryIdentities`` list to enable to lookup for notary parties known to the network. Related ``CordaRPCOps::notaryIdentities``

was introduced. Other special nodes parties like Oracles or Regulators need to be specified directly in CorDapp or flow.

many things, but as we switched to annotations and classpath scanning over time it hollowed out until this was

the only functionality left. You also need to rename your services resource file to the new class name.
