Copilot CLI v1.0.15: MCP Auth & Session Export

MCP OAuth device code flow for CI, session export as HTML, and performance fixes. Removed gpt-5.1-codex models and changed Ctrl+D behavior.

TL;DR

MCP OAuth now supports device code flow for headless/CI environments with account switching
New /share html command exports sessions as self-contained interactive HTML
Removed gpt-5.1-codex models; config keys now prefer camelCase (snake_case still works)
Performance fixes: CLI exits immediately, keystrokes no longer lost, slow MCP servers don't block startup

MCP device code flow (RFC 8628) — fallback OAuth method for headless and CI environments where interactive browser auth isn't possible
/mcp auth command — manage MCP OAuth re-authentication with account switching support
/share html command — export sessions and research reports as self-contained interactive HTML files
MCP server RPCs — mcp.config.list, mcp.config.add, mcp.config.update, mcp.config.remove for persistent MCP server configuration management
postToolUseFailure hooks — new hook for handling tool errors; postToolUse now runs only after successful tool calls
Diff viewer navigation — Home/End and Page Up/Page Down keys now work in the diff viewer
Copilot mascot animations — subtle eye blinking in interactive mode

CLI no longer waits up to 10 seconds after session ends — exits immediately
Keystrokes typed while CLI is loading are no longer lost
Large tool output preview now shows correct character count and displays up to 500 characters
Autopilot no longer continues after pressing Escape or Ctrl+C
MCP servers that are slow to connect no longer block agent startup
Pasting images from Windows clipboard now works in WSL environments
User switcher and /user list now display accounts in alphabetical order

Removed gpt-5.1-codex models — gpt-5.1-codex, gpt-5.1-codex-mini, and gpt-5.1-codex-max are no longer supported
Ctrl+D behavior changed — no longer queues a message; use Ctrl+Q or Ctrl+Enter instead
Config key naming — settings now prefer camelCase (askUser, autoUpdate, storeTokenPlaintext, logLevel, skillDirectories, disabledSkills); snake_case still accepted for backward compatibility

Update with: npm install -g @github/copilot-cli@latest
