Updates hardhat from 2.4.1 to 2.17.3

Release notes

Sourced from hardhat's releases.

Hardhat v2.17.3

This version of Hardhat changes the default evmVersion to paris for solc versions newer than or equal to 0.8.20.

Starting from version 0.8.20, solc changed the default target EVM version to Shanghai. Among other things, this meant that the generated bytecode could (and most likely would) contain the new PUSH0 opcode.

Up until this point, Hardhat always delegated to solc the decision of which EVM version to target. But there are two things that are different today: many users develop for non-mainnet chains, and not every chain has adopted the Shanghai hardfork yet. This means it's possible that you develop a contract which works locally (Hardhat's default hardfork is still Shanghai, because we follow the current mainnet hardfork) but that then doesn't work after deploying it.

If you are sure you are going to deploy in a network that supports the Shanghai hardfork, you can change the target EVM like this:

module.exports = {
  solidity: {
    version: "0.8.20",
    settings: {
      evmVersion: "shanghai",
    },
  },
};

Hardhat v2.17.2

This release includes several fixes and some new features:

• Added support for state overrides in the eth_call RPC method
• Added an enableTransientStorage option to enable EIP-1153 opcodes
• Deprecated the TASK_COMPILE_TRANSFORM_IMPORT_NAME subtask, added a new TASK_COMPILE_GET_REMAPPINGS subtask, and added support for remappings in the resolver.
• Fixed a problem that was causing debug_traceTransaction to return traces where the memory had a lot of empty words
• Fixed an issue where artifactExists would throw an error for missing artifacts
• Improved the error message displayed when importing a directory instead of a file
• Fixed a problem with receipts of remote transactions returning the wrong tx type when fetched through a fork

Hardhat v2.17.1

This release adds support for solc v0.8.21, allows using console.log in pure functions and improves the output of the flatten task (see NomicFoundation/hardhat#1499).

Besides that, this version:

• Removed an unnecessary dependency (abort-controller) because it's no longer needed in the versions of node.js supported by Hardhat (thanks @​orlandoortegajr!)
• Fixed a bug caused by nodes returning 429 responses without a Retry-After header (thanks @​kowalski!)
• Added logic to throw an error when the debug_traceTransaction method is called with a tracer parameter that is not supported.

Hardhat v2.17.0

This new minor version of Hardhat drops support for Node.js v14 and adds support for Node v20. To learn about which versions of Node we support, check our Stability guarantees page.

This version also adds support for solc 0.8.19 and 0.8.20 and fixes two bugs:

• A long-standing issue related to our compilation pipeline (see NomicFoundation/hardhat#1117).
• A problem when forking other local development networks whose latest block number has a low value (issue NomicFoundation/hardhat#1568).

Hardhat v2.16.1

This release fixes an issue in the compiler download that happens when Hardhat is used with node v18.16.x (the latest versions of node v18).

Hardhat v2.16.0 - Extendable providers
