v0.11.0

Overview

The Hedera Smart Contracts v0.11.0 release introduces a significant enhancement with the resolution of IHRC632 and IHRC904 definitions, addressing long-standing gaps in the repository. This update provides clear definitions for HIP 632, 904, and 906, introducing dedicated interface contracts like IHRC632, IHRC904, and IHRC906 to define HIP-specific functions callable by contracts. It also differentiates facade contracts for direct interaction by both EOAs and contracts, ensuring clarity and modularity. Key additions include hbarAllowance() and hbarApprove() in IHRC906Facade.sol, as well as new utility functions like getEvmAddressAlias() and isAuthorizedRaw(), which streamline integration with the system contract. This foundational work lays the groundwork for future compatibility and system contract refinements.

Beyond this major update, the release features several other enhancements, including an indexing tool for ERC contracts and improved test coverage for key functionalities like isAuthorizedRaw() (HIP-632). Bug fixes and dependency upgrades, such as updates to @hashgraph/sdk and @openzeppelin/hardhat-upgrades, ensure stability and compatibility. Internal changes like the introduction of an ERC Registry indexing tool targeting localnet and improved CI workflows demonstrate ongoing efforts to make the codebase more robust and developer-friendly.

v0.10.1

Overview

The Hedera Smart Contracts v0.10.1 release introduces key enhancements and new features, further aligning with important Hedera Improvement Proposals (HIPs). Noteworthy updates include the addition of the isAuthorizedRaw function, supporting the Hedera Account Service (HIP-632), which improves authorization checks. Additionally, test coverage has been expanded with new examples for HIP-719’s isAssociated() functionality and comprehensive tests for HIP-1010, enhancing the security and functionality of Hedera's contract services.

This release also strengthens the platform's debugging capabilities with the introduction of debug_traceTransaction tests, which utilize opcode logging for deeper insights during contract execution. These improvements enable developers to better trace transaction flows and optimize contract behavior. Furthermore, a major code clean-up effort was undertaken, where all references to "precompile" were replaced with "system contract," bringing greater clarity to the project's structure. This update not only renamed test directories and files but also revised the documentation to reflect the updated terminology, ensuring a more cohesive development environment.

In addition to these major updates, several dependency upgrades were implemented to improve security, compatibility, and overall performance. These updates ensure the system remains up to date with the latest standards and continues to provide a reliable foundation for smart contract development.

v0.8.0

Overview

The v0.8.0 release of the hashgraph/hedera-smart-contracts repository encompass a range of enhancements and refinements aimed at improving functionality and maintainability. Key highlights include the migration from ethers.js version 5.x to 6.x, ensuring compatibility and potentially benefiting from new features or optimizations.

Additionally, there's a focus on managing dependencies more efficiently, with updates to various packages and libraries. The introduction of the hardhat-abi-exporter plugin adds a streamlined approach to generating ABI-only artifacts, facilitating easier reference without cluttering the repository with unnecessary default artifacts.

Furthermore, efforts have been made to stabilize tests, enhance documentation, and clean up Solidity warnings, all contributing to a more robust and polished codebase. These changes collectively aim to elevate the overall quality and usability of the project.

v0.7.0

Overview

The v0.7.0 release of the hashgraph/hedera-smart-contracts repository introduces a spectrum of enhancements and additions. The project is now updated to integrate the latest 5.0.0 version of OpenZeppelin contract packages. This update is complemented by a varied collection of smart contracts, illustrating the compatibility of Solidity at the language layer and the Yul inline-assembly.
