Multi-repo support lets you query pull requests, issues, and activity across several repositories from a single Slack or Teams chat. You can mention @GitHub anywhere in a message, not just at the start, for more natural conversation. Smoother repository switching during a chat is now easier, requiring fewer steps. Copilot can use shared Slack messages and threads as context, eliminating the need to copy-paste details. Reliability improvements reduce errors and help the assistant recover more smoothly from interruptions.
