Added

• Add enterprise permissions.limitTo to enforce managed domain boundaries for network requests

Improved

• Model picker updates the recommended list to prioritize GPT-6.1 Sol, GPT-6 Astra/Luna, and Claude 5.5 models.

Fixed

• GitHub.com Connector users can expand GitHub CLI permissions in place and retry connections without switching sign-in methods.
• Honor --context long_context at startup and show accurate context allowance in /context
• Connecting a Connector without the required GitHub scope now prompts to update your authorization instead of failing with an authentication error

Removed

• Read user settings only from ~/.copilot/settings.json; user-setting keys in ~/.copilot/config.json are ignored.

Fixes and changes

Fixed

• Warmed language servers stay running across LSP requests when sandboxing is disabled
• Clicking a truncated compact shell command expands it

2026-10-05

• Add copilot config subcommands to list, read, set, and remove settings.
• Add a pre-conversation Ctrl+E environment picker to switch between local and cloud runs
• Entra-protected MCP servers can silently renew access-token-only credentials.
• Legacy HTTP+SSE MCP connections no longer hang indefinitely when a message POST is never acknowledged; the acknowledgement is bounded by the server's configured timeout
• Voice runtime install errors name why the download from nuget.org failed, not only the fallback feed's 401
• Compaction keeps your latest prompt when requests exceed context limits
• Large Anthropic requests rejected by provider size limits now retry after downscaling images or removing attachments
• Custom agent model entries keep model-bound reasoning effort only when that model is selected
• Shell tool calls now stream live stdout and stderr output reliably in the timeline
• Usage reporting preserves provider-reported reasoning token totals when available
• Sessions no longer slow to a crawl for minutes after the agent writes a very large file in one step
• Sandboxed shells now withhold ambient GITHUB_TOKEN unless explicitly configured.
• Plan usage reflects the current billing period after quota resets
• Custom agents launched through ACP task calls now resolve and run correctly
• Remote session resume now uses your configured GitHub auth for --resume and --connect
• Entra sign-in falls back to browser auth when no broker is available and shows a manual URL when auto-open fails
• copilot sandbox ca commands now respect --config-dir (including with -C).
• Search commands avoid sandbox bypass prompts when access is already granted
• Sandboxed uv commands can write to the uv cache by default when dev tool access is enabled
• pnpm commands run in sandboxed sessions without lock-file permission errors
• Pressing n repeatedly in the Sessions tab reliably creates each new session
• Reverse search updates results when command history finishes loading at startup
• MCP tools recover within the same turn when server instructions change
• Changing experimental mode with /experimental or /settings takes effect after restart even when launched with an opposing experimental flag
• Keyboard, paste, and mouse input now stay ordered and responsive during rapid interaction.
• Sandboxed shell commands offer a network bypass prompt whenever the proxy blocks a destination
• Sandboxed scripts that run Git now authenticate with masked credentials and SSH remote rewrites
• Sub-agents keep working after you replace your GitHub authentication credentials
• Sandboxed commands on Windows write temporary files to the granted temp directory, so tools that rename a temp file into place work
• Prompt-mode sessions fire a single sessionEnd hook after Stop-hook continuations complete
• Reconnect to remote MCP servers after idle Streamable HTTP sessions expire
• Messaging a running background agent now steers its active turn at the next processing opportunity.
• Context rollovers keep your latest requests in the recovery context.
• Hide the automatic sandbox CA setup prompt on Windows accounts that cannot self-elevate
• Copilot no longer describes a subagent as configured when the current session cannot run it. Previously a session that could not use rubber-duck still reported it as set up in /subagents, and asking for it failed instead of being skipped cleanly.
• MCP tools continue working after OAuth reauthentication when tool definitions are unchanged
• Select which account to use after Microsoft Entra sign-in, and let /logout sign out those OAuth sessions.
• Improve first-run startup by extracting the bundled CLI package in a child process
• Improve startup responsiveness when connecting many MCP servers at once
• Canvas actions can now return images to the model in invoke_canvas_action.
• Remove retired models from the model picker and supported CLI selections
