Full Changelog: v0.7.0-beta1...v0.7.0-beta2

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);
