Hardhat v2.20.0 — Cancun

This release adds support for the upcoming cancun 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: "cancun",
    },
  },
}

Keep in mind that blob transactions are not supported yet. If you need this, please upvote or comment on this issue.

In addition, this release adds support for solc 0.8.24.
