## Summary

Microsoft released VS Code version 1.141 on October 7, merging GitHub Copilot and OpenAI Codex sessions into a single workflow. Developers can now resume coding conversations started in Copilot CLI, the standalone Copilot app, or ChatGPT/Codex CLI within VS Code, with full history intact. The update also introduces a grid layout for managing multiple agent sessions, session filtering, and a cleanup tool for inactive worktrees to reclaim disk space—up to 100GB, according to Microsoft’s estimates for large projects. Sandboxing for AI agents expands to Windows, macOS, and Linux, restricting file and network access to mitigate risks like prompt injection. Organizations can enforce sandboxing via preview managed settings, though Microsoft notes it does not replace endpoint security.

New features include a Copilot harness for consistent agent behavior across VS Code, GitHub Copilot, and CLI, and experimental Dev Containers for .NET, Go, Node.js, PHP, Python, and Rust. The update also addresses GitHub Enterprise authentication by allowing multiple instance logins. Other changes include editor improvements like block pasting, a modernized interface, and a named chat pet, Blobby. The release is available now for all platforms, with experimental features in Insiders builds.

## Key points

- VS Code 1.141 lets developers sync Copilot/Codex sessions across apps with full history, requiring closing the original session first
- New sandboxing limits agent access to files/networks on Windows, macOS, and Linux, with enterprise enforcement options
- Grid layout, session filtering, and cleanup tools for inactive worktrees (up to 100GB reclaimable) improve agent management

## Why it matters

Unified agent workflows and stricter security reduce friction for developers using Copilot/Codex daily, while sandboxing addresses growing concerns about AI-driven code risks in enterprise environments.
