Updates @openzeppelin/hardhat-upgrades from 3.9.1 to 4.1.0

Release notes

Sourced from @​openzeppelin/hardhat-upgrades's releases.

@​openzeppelin/hardhat-upgrades@​4.1.0

  • Add a viem-based API at @openzeppelin/hardhat-upgrades/viem, following @nomicfoundation/hardhat-viem conventions: contracts are identified by name, addresses are typed as `0x${string}`, and the returned contract instances are viem contract instances. (#1279)
    • To use the viem-based API, install viem and @nomicfoundation/hardhat-viem, then import both the plugin (for your Hardhat config's plugins array) and the API (for your scripts) from @openzeppelin/hardhat-upgrades/viem. It supports wallet clients backed by local accounts, such as viem's privateKeyToAccount. The proxyFilesToBuild helper for Solidity tests is also exported from this entry point, so viem-only projects can configure npmFilesToBuild without importing the ethers-typed root entry.
    • The ethers-based API is unchanged. Import its plugin and API from @openzeppelin/hardhat-upgrades as before, or from the new @openzeppelin/hardhat-upgrades/ethers alias.
    • Potentially breaking changes: ethers and @nomicfoundation/hardhat-ethers are now optional peer dependencies, required only by the ethers-based API; viem-only projects no longer need them. If you use the ethers-based API, install them explicitly with npm install --save-dev @nomicfoundation/hardhat-ethers ethers. Previously they were required peer dependencies that package managers installed automatically.

@​openzeppelin/hardhat-upgrades@​4.0.2

  • Re-export @nomicfoundation/hardhat-ethers types so that TypeScript recognizes connection.ethers when only this plugin is registered. (#1275)

@​openzeppelin/hardhat-upgrades@​4.0.1

  • Update dependencies. (#1255)

@​openzeppelin/hardhat-upgrades@​4.0.0

  • Migrate to Hardhat 3 with ESM module structure and plugin hooks architecture. (#1241)

    Breaking Changes

    • Requires Hardhat 3: minimum hardhat@^3.6.0 required.
    • ESM-only: package converted to ESM; CommonJS is no longer supported.
    • API Changes:
      • No automatic hre.upgrades — call the upgrades(hre, connection) factory explicitly.
      • Factory functions (upgrades, defender) are async and require a network connection.
      • Network connection must be explicitly created: const connection = await hre.network.create(). Share one connection across operations.
      • ethers now comes from the connection (const { ethers } = connection), not hre.ethers.
    • Import Changes: import factory functions instead of a side-effect import.
      • Before: import '@openzeppelin/hardhat-upgrades'
      • After: import { upgrades, defender } from '@openzeppelin/hardhat-upgrades'

    Usage and Migration

    See the README for Hardhat 3 usage, the examples directory for sample projects, and the Migration Guide for Hardhat 2 to 3 migration steps.

    Changes

    • Migrated from extendEnvironment to Hardhat 3's HardhatPlugin with hookHandlers.
    • Converted package to ESM.
    • Etherscan verification requires @nomicfoundation/hardhat-verify@^3.0.10 (optional peer dependency).
    • Support
