Claude Code 2.1.181 + 2.1.185 — Inline /config, Bun 1.4, cloud-sync fix

What's new

• Inline /config: new /config key=value syntax (e.g. /config thinking=false)
• Apple Events sandbox opt-in: sandbox.allowAppleEvents on macOS for open/osascript/browser auth
• CLAUDE_CLIENT_PRESENCE_FILE: env var to suppress mobile notifications when you're at the keyboard
• Bun 1.4: bundled runtime upgrade
• Per-line streaming: long paragraphs no longer wait for the first break
• Zero-byte write fix: Write/Edit produced 0-byte files on network drives and cloud-sync folders (OneDrive/Dropbox/iCloud)
• Prompt cache fix: on custom ANTHROPIC_BASE_URL and Foundry
• Stream-stall hint (2.1.185): softer wording 'Waiting for API response · will retry in …', triggers after 20s instead of 10s

Why it matters

The zero-byte fix was a quiet data-loss hazard for enterprise teams on cloud sync. Inline /config simplifies hooks and scripts. Bun 1.4 brings perf gains for plugin authors. The reworded stream-stall hint stops healthy long Opus 4.8 runs from looking broken.

How to try it

Update to 2.1.181+ or 2.1.185+. Apple Events sandbox is an explicit opt-in.
