Claude Code's June 17 changelog adds `/config key=value`, a presence file, and an Apple Events opt-in.

You can now set any setting inline from the prompt, like /config thinking=false, in interactive, headless -p, and Remote Control modes. A new CLAUDE_CLIENT_PRESENCE_FILE env var suppresses mobile push while you're at the machine. sandbox.allowAppleEvents lets sandboxed commands drive native macOS apps without dropping the sandbox. Bundled Bun bumped to 1.4. The inline config is the one I'll use daily, scripting per-invocation overrides instead of juggling settings files. (Claude Code Docs)
