----------
* Support for external user credentials data source and password encryption [CORDA-827].
* The network map service concept has been re-designed. More information can be found in :doc:`network-map`.
* The previous design was never intended to be final but was rather a quick implementation in the earliest days of the
Corda project to unblock higher priority items. It sufffers from numerous disadvantages including lack of scalability,
as one node is expected to hold open and manage connections to every node on the network; not reliable; hard to defend
against DoS attacks; etc.
* There is no longer a special network map node for distributing the network map to the other nodes. Instead the network
map is now a collection of signed ``NodeInfo`` files distributed via HTTP.
* The ``certificateSigningService`` config has been replaced by ``compatibilityZoneURL`` which is the base URL for the
doorman registration and for downloading the network map. There is also an end-point for the node to publish its node-info
object, which the node does each time it changes. ``networkMapService`` config has been removed.
* To support local and test deployments, the node polls the ``additional-node-infos`` directory for these signed ``NodeInfo``
objects which are stored in its local cache. On startup the node generates its own signed file with the filename format
"nodeInfo-*". This can be copied to every node's ``additional-node-infos`` directory that is part of the network.
* Cordform (which is the ``deployNodes`` gradle task) does this copying automatically for the demos. The ``NetworkMap``
parameter is no longer needed.
* For test deployments we've introduced a bootstrapping tool (see :doc:`setting-up-a-corda-network`).
* ``extraAdvertisedServiceIds``, ``notaryNodeAddress``, ``notaryClusterAddresses`` and ``bftSMaRt`` configs have been
removed. The configuration of notaries has been simplified into a single ``notary`` config object. See
:doc:`corda-configuration-file` for more details.
* Introducing the concept of network parameters which are a set of constants which all nodes on a network must agree on
to correctly interop.
* The set of valid notaries has been moved to the network parameters. Notaries are no longer identified by the CN in
their X500 name.
* Single node notaries no longer have a second separate notary identity. Their main identity *is* their notary identity.
Use ``NetworkMapCache.notaryIdentities`` to get the list of available notaries.
* The common name in the node's X500 legal name is no longer reserved and can be used as part of the node's name.
* Moved ``NodeInfoSchema`` to internal package as the node info's database schema is not part of the public API. This
was needed to allow changes to the schema.
* Exporting additional JMX metrics (artemis, hibernate statistics) and loading Jolokia agent at JVM startup when using
DriverDSL and/or cordformation node runner.

deploys nodes for development and testing, the latter turns a project into a cordapp project that generates JARs in
the standard CorDapp format.
* ``Cordform`` and node identity generation:
* Removed the parameter ``NetworkMap`` from Cordform. Now at the end of the deployment the following happens:
1. Each node is started and its signed serialized NodeInfo is written to disk in the node base directory.
2. Every serialized ``NodeInfo`` above is copied in every other node "additional-node-info" folder under the NodeInfo folder.
* Nodes read and poll the filesystem for serialized ``NodeInfo`` in the ``additional-node-info`` directory.
* ``Cordapp`` now has a name field for identifying CorDapps and all CorDapp names are printed to console at startup.
* Enums now respect the whitelist applied to the Serializer factory serializing / deserializing them. If the enum isn't
either annotated with the @CordaSerializable annotation or explicitly whitelisted then a NotSerializableException is
thrown.
* ``extraAdvertisedServiceIds`` config has been removed as part of the previous work to retire the concept of advertised
services. The remaining use of this config was for notaries, the configuring of which has been cleaned up and simplified.
``notaryNodeAddress``, ``notaryClusterAddresses`` and ``bftSMaRt`` have also been removed and replaced by a single
``notary`` config object. See :doc:`corda-configuration-file` for more details.
* Gradle task ``deployNodes`` can have an additional parameter ``configFile`` with the path to a properties file
to be appended to node.conf.

allows services to start flows marked with the ``StartableByService`` annotation. For backwards compatability
service classes with only ``ServiceHub`` constructors will still work.
* ``TimeWindow`` now has a ``length`` property that returns the length of the time-window, or ``null`` if the
time-window is open-ended.
* ``TimeWindow`` now has a ``length`` property that returns the length of the time-window as a ``java.time.Duration`` object,
or ``null`` if the time-window isn't closed.
* A new ``SIGNERS_GROUP`` with ordinal 6 has been added to ``ComponentGroupEnum`` that corresponds to the ``Command``
signers.

* The ``ReceiveTransactionFlow`` can now be told to record the transaction at the same time as receiving it. Using this
feature, better support for observer/regulator nodes has been added. See :doc:`tutorial-observer-nodes`.
* Moved ``NodeInfoSchema`` to internal package as the node info's database schema is not part of the public API. This is
needed to allow new ``node_info_hash`` column to be added for the network map redesign work.
* Added an overload of ``TransactionWithSignatures.verifySignaturesExcept`` which takes in a collection of ``PublicKey``s.
* Replaced node configuration parameter ``certificateSigningService`` with ``compatibilityZoneURL``, which is Corda
compatibility zone network management service's address.
* ``DriverDSLExposedInterface`` has been renamed to ``DriverDSL`` and the ``waitForAllNodesToFinish()`` method has instead
become a parameter on driver creation.
* ``waitForAllNodesToFinish()`` method in ``DriverDSLExposedInterface`` has instead become a parameter on driver creation.
