Walkthrough

A new consensus deployment named DEPLOYMENT_V23 was introduced across the codebase. This deployment is added to the consensus parameters for all network types with specific activation parameters, including bit assignment, start time, timeout, window size, threshold, falloff coefficient, and the useEHF flag. The deployment is registered in the consensus deployment enumeration and described in the version bits deployment info array with the gbt_force flag set. The getblockchaininfo RPC command now reports the status of this new deployment, and related functional tests were updated to expect and validate the presence of the new "v23" softfork entry in RPC responses. No existing deployments or other consensus parameters were modified or removed.

⚡️ Faster reviews with caching

CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.
Enjoy the performance boost—your workflow just got faster.

  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • 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 explain this code block.
  • @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 explain its main purpose.
  • @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.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

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.

NOTE: this doesn't actually implement any "hard forking" changes, but simply adds the deployment, so that futures PRs which do add "hard forking" changes do not conflict with each other.
