Claude Code 2.1.302 turns fork subagents on by default in claude -p, the Agent SDK, desktop, and VS Code
Claude Code v2.1.302 (Oct 16) enables fork subagents everywhere the terminal already had them (set CLAUDE_CODE_FORK_SUBAGENT=0 to opt out) and adds CLAUDE_CODE_AUTO_MODE_MODEL to pick the model behind the client-side auto mode classifier. The release also notes that standalone Claude Design at claude.ai/design closes on December 14, 2026.
