·2026.04.24 05:17

Key point

GitHub Copilot Chat has strengthened pull request context and its review/summary features.

Details

GitHub Copilot Chat now understands pull requests and diffs more deeply, and can handle questions, reviews, and summaries directly within the PR workflow.

  • You can ask questions about a PR from the chat screen at github.com/copilot, and you can also open chat over surfaces across GitHub from the global Copilot navigation.
  • Public preview users can click the Copilot button in a diff to ask follow-up questions and understand the changes.
  • When a PR is brought in as context, Copilot factors in comments, file changes, commits, and reviews to answer.
  • If you ask it to review a PR, Copilot Chat provides a structured review, and if you ask for a summary, it returns a concise overview of the changes.
  • Suggested prompts have also been updated so you can immediately use related features, such as Help review this pull request.
