v2.63.0

What's Changed

Summary

The latest release of the Hedera Go SDK, version v2.63.0, brings several functional enhancements, new features, and critical fixes aimed at improving multi-node signing workflows, developer control over token creation, and support for new HIP proposals.

Key updates include improved support for offline multi-node, multi-signature transactions via the introduction of GetSignableBodyBytes and AddSignatureV2. This significantly enhances offline signing workflows, especially for chunked transactions like FileAppendTransaction.

The SDK now aligns with HIP-1064, allowing node operators to opt out of daily rewards via SetDeclineReward, and supports HIP-1046 by introducing gRPC-Web proxy endpoints for nodes, facilitating web-based interactions without requiring native gRPC support.

A regression related to TokenCreateTransaction has also been addressed, ensuring autoRenewAccount is only auto-set when an auto-renew period is specified, giving developers more predictable transaction behavior.

Enhancements

• Offline Multi-Node Signing Support (#1378)
  New APIs in Transaction.go:

  • GetSignableBodyBytes: Returns a list of SignableBody objects for each signed transaction.
  • AddSignatureV2: Adds a signature for specific TransactionID and NodeID, supporting chunked transactions like FileAppendTransaction.
    [Design Proposal Reference](https://github.com/hiero-ledger/sdk-collaboration-hub/blob/main/proposals/manual-signature-hsm-design-proposal.md)

• HIP-1064: Daily Rewards For Active Nodes (#1383)
  New APIs for NodeCreateTransaction and NodeUpdateTransaction:

  • GetDeclineReward(), SetDeclineReward(bool)
  • Allow nodes to opt out of receiving rewards

• HIP-1046: gRPC-Web Proxy Support (#1383)
  New APIs:

  • GetGrpcWebProxyEndpoint(), SetGrpcWebProxyEndpoint(Endpoint)
  • Enables gRPC communication over HTTP for non-native clients

Bug Fixes

• Fixed regression in TokenCreateTransaction: now autoRenewAccount is only set automatically when an auto-renew period is provided. (#1386)

• Fixed issue with FileAppendTransaction where receipt validation was incomplete for multi-chunk transactions. This ensures more accurate feedback during chunked uploads. (#1379)
