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.
