GitHub Copilot CLI changelog: what's new each month

Every stable GitHub Copilot CLI release summarised by month: the highlights, new features, improvements, fixes and anything you need to act on. 3 months covered; the current month updates daily.

October 2026 · so far

2 releases: 1.0.91 → 1.0.92

October brought sandbox management improvements, configuration controls, and better handling of interrupted sessions and resource constraints. The CLI now offers more direct control over proxy certificates, environment selection, and settings.

Action needed
  • /sandbox ca install is now /sandbox ca create and trust

Highlights

  • New sandbox certificate authority commands let you manage proxy CA trust, create certificates, and rotate credentials.
  • Configuration subcommands let you list, read, set, and remove settings directly from the CLI.
  • Pre-conversation environment picker (Ctrl+E) lets you switch between local and cloud execution before running a command.
  • Read-only shell pipelines that are complete and statically analyzable can now skip manual approval and go straight to execution-evidence review.
  • Telemetry flushes before shutdown and large requests now retry after downscaling images or removing attachments.

New

  • Copilot sandbox ca commands: check, create, trust, rotate, and remove proxy CA trust; Windows unattended setup support.
  • Copilot config subcommands to list, read, set, and remove CLI settings.
  • Pre-conversation Ctrl+E environment picker to switch between local and cloud runs before execution.
  • Sandbox network bypass option for Node/npm EACCES socket denials on Windows.
  • Automatic silent renewal of access-token-only credentials for Entra-protected MCP servers.
  • Execution-evidence review for complete, statically analyzable read-only shell pipelines without explicit approval.

Improved

  • Session timelines now clear busy status after interrupted turns finish.
  • Sandboxed commands run on Windows versions without filesystem enumeration support, with a warning about potential PowerShell directory issues.
  • Footer text selection stays on the same visible line when footer size changes.
  • Legacy HTTP+SSE MCP connections no longer hang indefinitely; acknowledgement is bounded by server timeout.
  • Voice runtime install errors now report why the primary download from nuget.org failed, not just the fallback feed's 401.
  • Prompt compaction preserves your latest prompt when requests exceed context limits.
  • Large Anthropic requests rejected by provider size limits retry after downscaling images or removing attachments.
  • Custom agent model entries keep model-bound reasoning effort only when that model is selected.

Fixed

  • MCP connections no longer hang indefinitely waiting for message POST acknowledgement.
  • Voice runtime install failures now report the correct error source.
  • Sandboxed commands on Windows now handle systems without filesystem enumeration support.

September 2026

7 releases: 1.0.83 → 1.0.90

Improved

  • Session sidebar sorting options (Recent, Created, Name, classic None) now saved across restarts.
  • Resuming sessions now preserves marketplace plugins and skills after reload when overrides are absent.

  • Prompt mode exits successfully when a child task fails but parent recovers.

  • Auto tier shows quick feedback prompt after switching away from a manually selected model.

Fixed

  • Herdr terminal multiplexer is now detected correctly instead of mistaken for tmux, enabling keyboard protocol and notifications.
  • Autopilot stops after accepted task completion instead of continuing unexpectedly.
