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

This version of Hardhat adds a new extensibility point: you can now wrap Hardhat's network provider with your own logic.

This is done by using the new extendProvider configuration function:

extendProvider(async (provider, config, network) => {
  const newProvider = new MyProviderWrapper(provider);
  return newProvider;
});

Doing this means that all the JSON-RPC calls will go through your custom provider wrapper. You can use this to intercept and handle some requests while forwarding the rest to the original provider.

To learn more about this, read the "Extending the Hardhat provider" section in our docs. If you have questions about how to use this, please open a new discussion.
