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. It also emphasizes support for OpenZeppelin standard contracts on the Hedera network. Furthermore, comprehensive test coverage has been implemented to meticulously verify the correct behavior of the aforementioned contracts. Additionally, new GitHub Actions workflows, including a PR title check workflow, have been introduced. The CI/CD pipeline has been improved with new tests, checks, and runners for enhanced efficiency.
