GitHub Copilot CLI adds sandbox auth controls, worktree options and a plugins dashboard

GitHub Copilot CLI's August 2026 updates centered on sandbox and enterprise controls, worktree handling, and a plugins dashboard. Five releases shipped, from v1.0.78 to v1.0.82.

Sandbox changes landed in v1.0.79: tool directories on PATH inside the workspace, such as .venv/bin, no longer turn read-only, and the /sandbox dialog gained an Auth tab. The settings keys moved from sandbox.gitAuth and sandbox.ghAuth to sandbox.auth.git and sandbox.auth.gh with no migration, so old keys are ignored. The same release added a worktreeBaseRef setting, and /worktree, /worktree new and --worktree now start from HEAD by default. v1.0.78 added the experimental /new-worktree command and live tool-call durations. v1.0.81 made the plugins dashboard available through /plugin, /mcp or /skills, offers to restore sessions left open after a crash, and added defaultMode and defaultPermissionMode settings. Model support grew with kimi-k3, Gemini 3.7 Flash and xhigh reasoning effort for Grok 4.6. v1.0.82 fixed worktree switching and improved authentication error messages.
