GitHub Copilot in Visual Studio Code、3月リリース

VS Code moved to weekly stable releases. This changelog covers releases v1.111 through v1.115, the releases we shipped throughout March and early April 2026. The highlights include Autopilot for fully autonomous agent sessions (in public preview), integrated browser debugging, image and video support in chat, and a new unified editor for managing chat customizations.

Control how agents run

Agent permissions: Choose a permission level per session (Default, Bypass Approvals, or Autopilot) to control which actions or decisions require manual intevention. Applies to both local and Copilot CLI sessions.

Autopilot: Agents approve their own actions, automatically retry on errors, and work autonomously until the task completes. No manual approvals required. This feature is in preview.

Configurable thinking effort: Control how deeply reasoning models (e.g., Claude Sonnet 4.6 and GPT-5.4) think before responding, and do this directly from the model picker. Your preference persists across conversations.

Expand what agents can do

Debug with the integrated browser: Set breakpoints, step through code, and inspect variables in the integrated browser without leaving VS Code. The new editor-browser debug type works with most existing chrome and msedge configurations.

Nested subagents: Subagents can now invoke other subagents (chat.subagents.allowInvocationsFromSubagents), enabling complex multi-step workflows and better task decomposition.

Work with images and video: Attach screenshots and videos to your chat messages. Agents can return images or recordings of changes that you can review in the carousel. Preview them in a full-featured carousel with zoom, pan, and thumbnail navigation.

CLI and Claude agent improvements: MCP servers configured in VS Code now work in Copilot CLI and Claude agent sessions. You can also fork any session to explore alternative approaches while keeping the original conversation intact.

Simplify customization and debugging

Chat customizations editor: Create and manage all your instructions, custom agents, skills, and plugins from one unified interface. Browse MCP and plugin marketplaces directly from the editor. This feature is in preview.

Faster workspace search: The #codebase tool now runs purely semantic searches against a single auto-managed index. No more local vs. remote indexing—just faster, more consistent results.

Sandbox MCP servers: Run local MCP servers in a restricted sandbox to limit file and network access (macOS and Linux).

Diagnose with /troubleshoot: Analyze agent debug logs directly in chat to understand unexpected behavior, why instructions were ignored, or why responses were slow, including from past sessions.

Monorepo customizations: VS Code now discovers instructions, agents, skills, and hooks from parent folders up to the repository root, making it easier to share team-wide configurations across packages.

Agent-scoped hooks: Attach pre- and post-processing logic to specific custom agents without affecting other chat interactions (chat.useCustomAgentHooks). Define hooks in the YAML frontmatter of .agent.md files. This feature is in preview.
