0.7.0-beta1

Key Highlights

1. New Wallet API (Preview)
   A wrapper around the existing Account API that provides the capability to scan multiple addresses under the same wallet for UTxOs. It also keeps track of the derivation path to find the correct signer based on UTxO selection and it's compatible with QuickTx api.

   Examples: For examples, please check these integration tests

   Note: This API is in preview. It should not be used in production yet.

2. [CIP 129] Gov Identifiers Implementation
   Implementation of the CIP 129 standard for governance identifiers.

3. New completeAndWaitAsync methods in the QuickTx API
   These methods return a CompletableFuture to enable asynchronous waiting, instead of the current blocking implementation:

   CompletableFuture<TxResult> completeAndWaitAsync() 
   CompletableFuture<TxResult> completeAndWaitAsync(Consumer<String> logConsumer)
   CompletableFuture<TxResult> completeAndWaitAsync(Consumer<String> logConsumer, Executor executor)
   CompletableFuture<TxResult> completeAndWaitAsync(Duration checkInterval, Consumer<String> logConsumer)
   CompletableFuture<TxResult> completeAndWaitAsync(Duration checkInterval, Consumer<String> logConsumer, Executor executor)

4. Refactoring of Value class : To include new utility methods. add, subtract (#457)

5. New methods in MetadataBuillder : To simplify the creation of different types of metadata (#467)

Breaking Change

• TxSigner.sign method signature update:
  The TxSigner.sign method now requires a TxBuilderContext parameter. If you build a transaction first and then sign it with a TxSigner, you must include the TxBuilderContext as part of the signing process.

Existing Code:

        TxSigner signer = SignerProviders.signerFrom(sender);
        
        Transaction transaction = TxBuilderContext.init(utxoSupplier, protocolParamsSupplier)
                .build(builder);
                
        Transaction signedTxn = signer.sign(transaction);

New Code :

        TxSigner signer = SignerProviders.signerFrom(sender);

        var txContext = TxBuilderContext.init(utxoSupplier, protocolParamsSupplier);
        Transaction transaction = txContext
                .build(builder);

        Transaction signedTxn = signer.sign(txContext, transaction);

0.6.0

This is the first stable release for the Conway Era. For all the changes since 0.5.1, please also refer to the 0.6.0-beta1 release notes.

Key Changes in This Release

• Fixed script data hash issues for Plutus V3 caused by Conway era serialization changes.
• Updated serialization code to provide era-specific serialization based on application requirements.
• Koios Java Client v1.19.0 and other fixes for the Conway era.
• Fixed Ogmios backend's Epoch service to return the Plutus V3 cost model.
• Blueprint annotation processor fixes.

Known Limitations and Workaround

When a transaction containing a Plutus V1 script or a script with a datum hash in the output is serialized using the Conway era format (Map for redeemer, 258 tag for set), a script data hash mismatch error occurs.

To resolve this, the library automatically uses the Babbage era serialization format if it detects a Plutus V1 script in the transaction, which should cover most cases automatically.

However, there are a few scenarios where the library doesn't enforce the Babbage era serialization format. One such scenario is a script transaction with a datum hash in the output (instead of an inline datum).

To address this, the library introduces a new method that applications can use to specify the serialization format. The default format is the Conway era format.

For QuickTx, there is a new withSerializationEra method that takes an era parameter:

Result<String> result = quickTxBuilder.compose(scriptTx)
                .feePayer(sender1Addr)
                ....
                .withSerializationEra(Era.Babbage)
                .completeAndWait(System.out::println);

For Composable Functions:

Transaction signedTxn = TxBuilderContext.init(utxoSupplier, protocolParams)
                .withSerializationEra(Era.Babbage)
                .buildAndSign(builder, signer);

For Low-Level Serialization APIs, you can directly set the serialization era in the Transaction object:

transaction.setEra(Era.Babbage);
