It restricts agent access to files, networks, and credentials at no extra cost. The Copilot app now supports separate GitHub accounts for license and repositories. Copilot CLI lets users discover and switch local models from Ollama. VS Code users can now view agent sessions side by side in a grid. Users can free disk space by cleaning up inactive session worktrees in chat.
