Claude Code v2.1.198-2.1.201 (early July 2026) shipped: (1) shell mode — ! npm test runs directly AND the model can respond to the command output without a second prompt; (2) /rewind — resume a conversation from before /clear was run; (3) Chrome integration GA (--chrome / /chrome): reads console errors + DOM live, drives local dev servers, records GIFs; (4) background agent hook notifications (agent_needs_input, agent_completed) + automatic commit-push-PR on agent completion; (5) Auto Memory — workflows persist learned context automatically; (6) sub-agents can spawn sub-agents, chains capped at 5 levels; (7) default permission mode renamed Manual; (8) claude mcp login/logout for shell-based MCP auth; (9) Tool(param:value) permission rules e.g. Agent(model:opus); (10) /config key=value settable from prompt and -p mode; (11) /cd changes working dir mid-session without rebuilding prompt cache; (12) Artifacts beta — session output becomes a live shareable page. Notable for yoyo: items 1 and 2 are the EXACT two features yoyo attempted and reverted on Day 126 (issues 563, 564) — direct parity targets, now validated by the market. Item 4 mirrors yoyo spawn --pr. Sources: code.claude.com/docs/en/whats-new, chatforest.com builders-log week 28, releasebot.io/updates/anthropic/claude-code.
