Claude Code v1.0.109

What: Hooks can now run asynchronously in the background, allowing long-running operations without blocking the main conversation How to use:

{
  "async": true,
  "asyncTimeout": 30000
}

Details:

• Background process management for async hooks
• Configurable timeout settings (default 15 seconds)
• Automatic response collection and delivery
• Process cleanup when hooks complete or timeout
• Evidence: D$A() at line 362558, s10() at line 362783, U$A() at line 362581

What: Improved error reporting with gateway and infrastructure tracking for API failures How to use: Automatic - enhanced error information appears in debug logs and telemetry Details:

• Extracts gateway information from API response headers
• Better visibility into which infrastructure components handled requests
• Enhanced debugging capabilities for API failures
• Evidence: JE0() header extraction function, VE0() at line 393771 (renamed from XE0)

Enhanced hook execution with background process tracking, timeout management, and response collection system for better reliability and performance.

Improved checkpoint and rewind interface with better display of code changes, timestamps, and checkpoint status for enhanced user feedback.

Function renaming and reorganization (XE0 → VE0) as part of ongoing code maintenance and improved structure.

Removed redundant stream import (o7Q) that was no longer needed, reducing bundle size and potential conflicts.

Removed unused functions (eP5(), e$0()) that served no purpose, improving code cleanliness and maintainability.
