Release notes

Sourced from hardhat's releases.

Hardhat v2.14.0 — Shanghai

This release sets Shanghai as the default hardfork used by the Hardhat Network.

If for some reason you want to keep using the previous hardfork, set it explicitly in your config:

module.exports = {
  networks: {
    hardhat: {
      hardfork: "merge"
    }
  }
}

Hardhat v2.13.1

This release adds support for the upcoming Shanghai hardfork. This hardfork is not enabled by default; if you want to use it, then you have to enable it in your Hardhat config:

module.exports = {
  networks: {
    hardhat: {
      hardfork: "shanghai"
    }
  }
}

Besides that, this version fixes a problem when importing scoped packages in a Yarn Berry monorepo that uses PnP (thanks @​zouguangxian!)

@​nomiclabs/hardhat-ethers v2.2.3

Make getContractFactory's params validation more flexible (thanks @​jtakalai!)

Hardhat v2.13.0 — ES Modules and compiling with viaIR

This new version of Hardhat adds two long-awaited features: ES Modules support, and better support for solc’s IR-based compilation pipeline. Besides that, this version includes several other improvements and bug fixes.

Remember to give this repo a star ⭐ if you are enjoying Hardhat!

ES Modules support

Hardhat was designed with CommonJS in mind, but in the last years adoption of ES Modules (ESM) has been growing. This version includes better support for it. You can now write scripts and tests as ESM, but your Hardhat config —and anything imported from it— still needs to use CommonJS.

ES modules let you use import/export and top-level await. This means that instead of writing a script like this:

// script.js
const helpers = require("@nomicfoundation/hardhat-network-helpers");
async function main() {
const latestBlockNumber = await helpers.time.latestBlock();
</tr></table>
