VS Code 1.140

Microsoft has released Visual Studio Code 1.140, the latest monthly update to its free cross-platform editor. The release landed on September 30, 2026, and its headline work revolves around agent coordination: shared Copilot behavior, multi-folder sessions, and remote delegation.

What Changed

The marquee addition is the Copilot harness, a layer that keeps agent behavior consistent across Copilot products. The same editing agent now behaves predictably whether it runs inline, in the chat panel, or through the CLI.

• Copilot harness - A shared execution layer that standardizes how agents handle tools, context, and permissions.
• Experimental multi-folder sessions - Individual chats can now work across multiple repositories or isolated worktrees from a single session.
• Shared worktree support - Better coordination when several developers work on the same repository.
• Remote agent delegation - Experimental support for handing tasks to agents hosted on remote machines.

Why It Matters

Multi-folder and multi-machine workflows have historically been a pain point in VS Code, which leans on a single workspace mental model. This release starts to dissolve that boundary, letting agent-driven work span repositories and hosts without leaving the editor.

What Is Next

Several of the headline capabilities remain experimental, so expect the harness and delegation features to harden over the next few monthly cycles. For most teams, the practical win today is the more consistent agent behavior and smoother worktree-based collaboration.
