Node.js 22 Required: This release raises the minimum Node.js version from 18 to 22. Run node --version to check; upgrade via your package manager or [nodejs.org](https://nodejs.org) before updating Claude Code. Any existing install scripts or CI environments pinned to Node 18 or 20 will need to be updated.

/agents wizard gone: Workflows relying on the interactive /agents menu (Create agent, Edit agent, Delete agent) no longer exist. Transition to asking Claude directly: "create a code-reviewer subagent that..." or edit .claude/agents/*.md files manually.
