Release notes
|
|
=============
|
|
|
|
Here are brief summaries of what's changed between each snapshot release.
|
|
|
|
Unreleased
|
|
----------
|
|
|
|
Here are changes in git master that haven't yet made it to a snapshot release:
|
|
|
|
* Made the ``NotaryService`` extensible, we now have both validating and non-validating notaries.
|
|
* Added a protocol for changing the notary for a state.
|
|
* Every ``ContractState`` now has to specify a *participants* field, which is a list of parties that are able to
|
|
consume this state in a valid transaction. This is used for e.g. making sure all relevant parties obtain the updated
|
|
state when changing a notary.
|
|
* Introduced ``TransactionState``, which wraps ``ContractState``, and is used when defining a transaction output.
|
|
The notary field is moved from ``ContractState`` into ``TransactionState``.
|
|
* Every transaction now has a *type* field, which specifies custom build & validation rules for that transaction type.
|
|
Currently two types are supported:
|
|
|
|
- **General**. Runs the default build and validation logic.
|
|
- **NotaryChange**. Contract code is not run during validation, checks that the notary field is the only difference
|
|
between the inputs and outputs.
|
|
|
|
* The cash contract has moved from com.r3corda.contracts to com.r3corda.contracts.cash.
|
|
* Amount class is now generic, to support non-currency types (such as assets, or currency with additional information).
|
|
* Refactored the Cash contract to have a new FungibleAsset superclass, to model all countable assets that can be merged
|
|
and split (currency, barrels of oil, etc.)
|
|
* Switched to the ed25519 elliptic curve from secp256r1. Note that this introduces a new external lib dependency.
|
