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);
