VS Code 1.141

Microsoft has released Visual Studio Code 1.141, the latest monthly update to its popular code editor, on October 7, 2026. The headline of this release is a major expansion of the Copilot agent experience, delivered through the new Copilot harness.

What Changed

The release introduces a session grid in the Agents window, letting developers drag agent sessions into horizontal or vertical splits and resize the panes to compare work side by side. The editor also now tracks how much disk space dead agent sessions waste and surfaces cleanup options, alongside new worktree cleanup controls.

• Copilot harness - New agent functionality powered by the Copilot SDK, keeping behavior consistent across the editor.
• Session grid - Split and resize agent sessions directly in the Agents window.
• Terminal sandboxing - Copilot sandboxing now extended across platforms.
• External chat - Chat integration expanded beyond the built-in panel.
• Columnar editing - Improved support for editing column-format data.
• Multi-instance GitHub Enterprise - Log in to multiple GitHub Enterprise servers at once.

Why It Matters

Version 1.141 shifts the focus from single-agent assistance to managing multiple running agents as a first-class workflow. The session grid and cleanup tools address practical pain points: keeping tabs on several agent sessions and reclaiming disk space after they finish. For teams running agent-heavy workflows, these are the changes that show up every day.

What's Next

As with every monthly release, 1.141 is available now via the built-in update mechanism on Windows, macOS, and Linux. Copilot users should also update the GitHub Copilot Chat extension, which received security-related updates in this cycle. Microsoft continues to iterate on the agent harness ahead of its broader Copilot SDK rollout.
