v2.21.0: Hardhat v2.21.0 — Introducing EDR

Compare Source

This version of Hardhat marks the debut of EDR (Ethereum Development Runtime), our new Rust-based runtime that is a complete rewrite of the original TypeScript-based Hardhat Network. This release lays a new long-term foundation for Hardhat's evolution over the coming year.

There are no functional changes, but there are some performance improvements across the board, which we’ll continue to expand in future updates.

Given the significance of this internal change, there’s a possibility of bugs. If you encounter any problems specific to this version, please report them by opening an issue. You should be able to downgrade to v2.20.1 without losing functionality if needed.

solidity-coverage out-of-memory issues

The solidity-coverage plugin works by heavily instrumenting the code, which sometimes causes OOM (out-of-memory) issues. This new version of Hardhat can, in certain cases, make those problems more likely.

If you run into this, you can fix it by using Node.js’s --max-old-space-size flag:

NODE_OPTIONS="--max-old-space-size=8192" npx hardhat coverage

Dropping support for Node.js v16

As part of this release, we are dropping support for Node.js v16. This version of Node.js reached its end-of-life in September of last year. You can learn more about our support guarantees here.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
