[Release] anthropics/claude-code v2.1.181: v2.1.181

Claude Code v2.1.181 introduces configuration shortcuts via `/config` syntax, improved streaming and retry mechanisms, enhanced subagent panel management, and fixes for prompt caching, file operations, and macOS compatibility. The release addresses startup performance regressions, network resilience, and numerous UI/UX improvements across interactive mode, Remote Control, and subagent workflows.

Key Points

• •New `/config key=value` syntax allows setting any configuration from prompts (e.g., `/config thinking=false`) across interactive, `-p`, and Remote Control modes
• •Added `sandbox.allowAppleEvents` opt-in setting for sandboxed commands to send Apple Events on macOS, fixing auth flow failures
• •Introduced `CLAUDE_CLIENT_PRESENCE_FILE` environment variable to suppress mobile push notifications when at the machine
• •Upgraded bundled Bun runtime to 1.4 for improved performance and compatibility
• •Improved streaming of long paragraphs to display line-by-line instead of waiting for first line break
• •Enhanced auto-retry logic: API connection drops mid-thinking now automatically retry instead of showing connection errors
• •Subagent panel improvements: idle subagents auto-hide after 30s, list caps at 5 rows with scroll, keyboard hints in footer
• •Fixed critical prompt caching issue on custom `ANTHROPIC_BASE_URL` and Foundry due to per-request attestation token changes
• •Resolved Write/Edit producing 0-byte or truncated files on network drives and cloud-synced folders
• •Fixed startup regressions: eliminated 120ms delay per launch and 15-second blocking on slow account settings fetch
