📦 The GitHub MCP registry is now integrated directly in VS Code stable! Browse and install MCP servers from the Extensions view with one click. Powered by the official GitHub MCP registry. Enable with ⚙️ `chat.mcp.gallery.enabled` setting.

🔀 Resolve merge conflicts with AI assistance! When VS Code detects merge conflicts, you can now get AI-powered resolution suggestions through an agentic Chat flow.

📋 AGENTS.md is now generally available and you can customize AI behavior for your entire workspace! 🆕 Experimental support for nested AGENTS.md files in subfolders - define different instructions for frontend, backend, and more. Learn more: code.visualstudio.com/docs/copilot...

🤖 Improved coding agent integration! The Delegate to coding agent button now appears by default in repos with Copilot coding agent enabled. Context from your conversation is automatically forwarded and summarized if needed.

✨ Enhanced Chat Sessions view with UI refinements and performance improvements. Manage multiple AI sessions, track coding agent progress, and quickly start new sessions with the "+" button.

🔔 Stay in the loop with OS notifications! Get notified when chat responses arrive or long-running tasks complete while VS Code is unfocused. Notifications include previews and bring you back to the action.

🧠 Chain of thought is here (experimental)! See the model's reasoning as it responds. With GPT-5-Codex, thinking tokens appear as expandable sections. Great for debugging and understanding AI suggestions. Configure with ⚙️ `chat.agent.thinkingStyle` setting.

📝 Fully qualified tool names prevent conflicts between built-in tools, MCP servers, and extensions. Use `search/codebase` instead of `codebase`. A code action helps you migrate existing prompt files.

💬 Pick up where you left off! Enable ⚙️`chat.emptyState.history.enabled` to see your recent local chat conversations when starting a new session. Quickly revisit past work.
