v2.57.0

What's Changed

Summary

This release introduces support for HIP-1046 and enhances node configuration with a new gRPC web proxy field in the address book schema, enabling node operators to manage web proxies directly. It also adds the grpcWebProxyEndpoint field to NodeCreateTransaction and NodeUpdateTransaction for non-gRPC client compatibility. Additionally, new APIs allow for transaction size estimation prior to submission, supporting better fee calculation, validation, and batching logic.

Added

• Support for HIP-1046. https://hips.hedera.com/hip/hip-1046
  • Introduced new grpc web proxy field in the address book schema, making node operators manage their web proxies. #2337
  • NodeCreateTransaction
    • Endpoint grpcWebProxyEndpoint - A web proxy for gRPC from non-gRPC clients.
    • Endpoint getGrpcWebProxyEndpoint()
    • NodeCreateTransaction setGrpcWebProxyEndpoint(Endpoint)
  • NodeUpdateTransaction
    • Endpoint grpcWebProxyEndpoint - A web proxy for gRPC from non-gRPC clients.
    • Endpoint getGrpcWebProxyEndpoint()
    • NodeUpdateTransaction setGrpcWebProxyEndpoint(Endpoint)
• Support transaction size calculation before submission. This is useful for fee estimation, transaction validation, and batching logic. #2330
  • Following APIs were implemented: #2324

    • Transaction.size: uint
      Returns the total size (in bytes) of the protobuf-encoded transaction, including signatures and metadata.

    • Transaction.bodySize: uint
      Returns the protobuf-encoded transaction body size (excluding signatures), using a placeholder node account ID.

    • ChunkTransaction.bodySizeAllChunks: uint[]
      For chunked transactions (e.g. FileAppendTransaction, TopicMessageSubmitTransaction), returns an array of body sizes for each chunk.
