Here are brief summaries of what's changed between each snapshot release.
Milestone 7
-----------
* With thanks to `Thomas Schroeter <https://github.com/thschroeter>`_ ``NotaryFlow`` is now idempotent.
* Explorer:
* The GUI for the explorer now shows other nodes on the network map and the transactions between them.
* Map resolution increased and allows zooming and panning.
* `Video demonstration <https://www.corda.net/2017/01/03/the-node-explorer/>`_ of the Node Explorer.
* The CorDapp template now has a Java example that parallels the Kotlin one for developers more comfortable with Java.
ORM support added to the Kotlin example.
* Demos:
* Added the Bank of Corda demo - a demo showing a node (Bank of Corda) acting as an issuer of Cash, and a client
driver providing both Web and RPC access to request issuance of cash.
* Demos now use RPC to communicate with the node from the webserver. This brings the demos more in line with how
interaction with nodes is expected to be. The demos now treat their webservers like clients. This will also allow
for the splitting of the webserver from the node for milestone 8.
* Added a SIMM valuation demo integration test to catch regressions.
* Security:
* MQ broker of the node now requires authentication which means that third parties cannot connect to and
listen to queues on the Node. RPC and P2P between nodes is now authenticated as a result of this change.
This also means that nodes or RPC users cannot pretend to be other nodes or RPC users.
* The node now does host verification of any node that connects to it and prevents man in the middle attacks.
* Improvements:
* Vault updates now contain full ``StateAndRef`` which allows subscribers to check whether the update contains
relevant states.
* Cash balances are calculated using aggregate values to prevent iterating through all states in the vault, which
improves performance.
* Multi-party services, such as notaries, are now load balanced and represented as a single ``Party`` object.
* The Notary Change flow now supports encumbrances.
