Summary

In this release, we introduced validation to ensure that TopicMessageSubmitTransaction messages cannot be empty and added support for customFeeLimits in scheduled transactions, starting with TopicSubmitTransaction. Several dependency upgrades were made. We also welcomed a new contributor, @emiliyank, with their first contribution to the project.

Added

• Validation for non-empty message for TopicMessageSubmitTransaction #2421

v2.62.0

What's Changed

Summary

This release introduces new node management capabilities and provides important guidance for the upcoming package namespace migration. This minor release enhances node configuration flexibility while preparing developers for the transition to Hiero branding.

Added

• Added new method deleteGrpcWebProxyEndpoint for NodeUpdateTransaction to remove gRPC web proxy endpoints from nodes that effectively sets the proxy to null in the mirror node API and removes the proxy configuration from the address book state

Important Notice

• Package naming will change from hedera to hiero over the next 6 months. All developers should begin planning for this transition.
  Comprehensive migration guide available: HIERO_MIGRATION.md

v2.61.0

What's Changed

Summary

This release focuses on enhanced transaction validation, modernized Java runtime support, and improved Ethereum transaction handling. We've strengthened node operation security with explicit validation checks and deprecated legacy Ethereum flow patterns in favor of more efficient JumboTransaction support.

Added

Node ID Validation: Implemented explicit nodeId validation before transaction execution for NodeUpdateTransaction and NodeDeleteTransaction operations

• Ensures transaction integrity and prevents invalid node operations
• Addresses security concerns with node management transactions

Hiero Namespace Migration Guide: Comprehensive documentation for developers transitioning to the Hiero namespace

• Step-by-step migration instructions for publishing under the new namespace
• Developer-focused guidance for seamless transition

Java 21 Support: Upgraded minimum Java version requirement from Java 17 to Java 21

• Access to latest Java features and performance improvements
• Enhanced security and stability with modern runtime support

Deprecated

EthereumFlow: Deprecated in favor of more efficient JumboTransaction support

Replacement: Use EthereumTransaction for improved performance and capabilities
Reason: Introduction of JumboTransactions provides better transaction handling for Ethereum operations

Dependency changes

• chore(deps): bump org.apache.commons:commons-lang3 from 3.17.0 to 3.18.0 in /hiero-dependency-versions by @dependabot[bot] in #2407

v2.60.0

What's Changed

Summary

This release introduces persistent shard and realm support for enhanced Client configuration stability and modernizes EVM address handling APIs while deprecating legacy methods for improved developer experience.

Added

Persistent Shard and Realm Support - Enhanced Client Configuration Stability

New persistent realm and shard support for Client configuration - Ensures consistent address book queries across client lifecycle events, providing more reliable network interactions and improved connection stability
Enhanced Client initialization with persistent network topology awareness

New fromEvmAddress() method
New toEvmAddress() method

Deprecated

Deprecated fromSolidityAddress() method - Replaced by more explicit fromEvmAddress() API for better clarity and consistency
Deprecated toSolidityAddress() method - Superseded by toEvmAddress()
