Asynchronous Hook Execution #

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

Enhanced API Error Tracking #

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)

Hook Registry Management #

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

Rewind Feature UI #

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

Code Organization #

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

Stream Import Cleanup #

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

Dead Code Removal #

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