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.
