GitHub Copilot VS Code March 2026 v1.111–v1.115

TL;DR

• Autopilot agents now run fully autonomous without manual approvals (public preview)
• Integrated browser debugging, image/video chat support, and nested subagents
• New unified chat customizations editor and faster semantic codebase search

New

• Autopilot agent mode — Agents approve their own actions and retry on errors without manual intervention. Set per-session permission levels (Default, Bypass Approvals, or Autopilot).
• Integrated browser debugging — Set breakpoints, step through code, and inspect variables in VS Code's built-in browser. Works with existing Chrome and Edge debug configs via new editor-browser type.
• Image and video in chat — Attach screenshots and recordings to messages. Agents can return visual proof of changes in a carousel with zoom, pan, and thumbnail navigation.
• Nested subagents — Subagents can invoke other subagents for complex multi-step workflows and better task decomposition.
• Chat customizations editor — Unified interface to create and manage instructions, custom agents, skills, and plugins. Browse MCP and plugin marketplaces directly (preview).
• Configurable thinking effort — Control reasoning depth for Claude Sonnet 4.6 and GPT-5.4 directly from the model picker. Preference persists across conversations.
• Faster codebase search — #codebase tool now runs pure semantic search against a single auto-managed index. No more local vs. remote confusion.
• Sandbox MCP servers — Run local MCP servers in restricted sandbox mode to limit file and network access (macOS and Linux).
• /troubleshoot command — Analyze agent debug logs directly in chat to diagnose unexpected behavior, ignored instructions, or slow responses from past sessions.
• Monorepo customizations discovery — VS Code now finds instructions, agents, skills, and hooks from parent folders up to repo root for team-wide configuration sharing.
• Agent-scoped hooks — Attach pre- and post-processing logic to specific custom agents via YAML frontmatter in .agent.md files (preview).
• Session forking — Fork any session to explore alternative approaches while keeping the original conversation intact.
• Copy Final Response — New command to copy only the agent's final answer, skipping thinking steps and tool calls.
• Automatic symbol references — Pasting code symbols into chat automatically adds references.
• Browser tab management — Quick Open, Close All, and title bar shortcuts for improved navigation.
• Self-signed certificate support — Integrated browser now works with local HTTPS development.
• TypeScript 6.0 support — Important fixes ahead of TypeScript 7.0 native rewrite.
• New default themes — Refreshed "VS Code Light" and "VS Code Dark" with modern design.

Breaking Changes

• MCP servers configured in VS Code now work in Copilot CLI and Claude agent sessions — ensure your MCP configurations are compatible with these environments.
