• Added new model:
  Run slash model to equip
  Haiku 4.5.
  

• Added a flag to augment MCP server configuration to temporarily add or override server configuration per session: --additional-mcp-config (fixes Add support for repo-specific / folder-specific MCP configs #288)
  • You can pass MCP server configuration in two ways:
    • Inline JSON: copilot --additional-mcp-config '{"mcpServers": {"my-tool": {...}}}'
    • From a file (prefix with @): copilot --additional-mcp-config @/path/to/config.json
  • You can also pass the flag multiple times (later values override earlier ones): copilot --additional-mcp-config @base.json --additional-mcp-config @overrides.json
• Improved our prompts to ensure the agent uses Windows-style paths on Windows (fixes Prompted for permission at every subdirectory, plus incorrect errors #261)
• Added a prompt for users to run /terminal-setup if needed to enable multi-line input
• Various visual improvements:
  • Added a shimmer effect to the "Thinking..." indicator
  • Removed the box around user messages in the timeline
  • Increased the contrast of removed intraline highlights in diffs
  • Allow cycling through slash commands (from the bottom of the list back to the top)
  • Aligned permission/confirmation prompts to ensure all use the same visual style

Run npm install -g @github/copilot@latest to update!
