Copilot CLI v1.0.15-1: MCP Config & Auth Fixes

Copilot CLI 1.0.15-1 adds MCP config management, device code OAuth flow for CI, HTML session export, and fixes autopilot cancellation. Breaking: Ctrl+D no longer queues messages.

TL;DR

New MCP server config RPCs for persistent configuration management
Device code flow fallback for headless/CI environments and /mcp auth command with account switching
Session export as self-contained HTML and improved diff viewer navigation
Breaking: Ctrl+D no longer queues messages; use Ctrl+Q or Ctrl+Enter instead

New

MCP config RPCs — mcp.config.list, mcp.config.add, mcp.config.update, and mcp.config.remove for managing persistent MCP server configuration
Device code flow (RFC 8628) — fallback OAuth method for headless and CI environments where interactive login isn't possible
/mcp auth command — re-authentication UI for MCP OAuth servers with account switching support
/share html command — export sessions and research reports as self-contained interactive HTML files
postToolUseFailure hooks — handle tool errors; postToolUse now runs only after successful tool calls

Improved

Diff viewer navigation — Home/End and Page Up/Page Down keys now work in the diff viewer
Session exit speed — CLI exits immediately after a session ends instead of waiting up to 10 seconds
Config naming — askUser, autoUpdate, storeTokenPlaintext, logLevel, skillDirectories, and disabledSkills now use camelCase (snake_case still accepted for backward compatibility)

Fixed

Autopilot cancellation — no longer continues after pressing Escape or Ctrl+C
Keystroke loss — keystrokes typed while the CLI is loading are no longer lost
Tool output preview — large tool output now shows correct character count and displays up to 500 characters
