Claude Code v1.0.41

# Claude Code v1.0.41 Changelog

The hook execution system now supports individual timeout configurations for each command within a hook. Previously, all commands shared a single global timeout, but now each command can specify its own timeout value.

Usage Example: When configuring hooks, you can now specify a timeout for individual commands:

{
  "hook_event_name": "pre-commit",
  "commands": [
    {
      "command": "npm test",
      "timeout": 30  // 30 seconds timeout
    },
    {
      "command": "npm run lint",
      "timeout": 10  // 10 seconds timeout
    }
  ]
}

A new hook event type SubagentStop has been added to the available hook events. This allows you to configure commands that run when a subagent completes its execution.

Available hook events now include:

• PreToolUse - Before a tool is executed
• PostToolUse - After a tool completes
• Notification - For notification events
• Stop - When the main process stops
• SubagentStop - When a subagent completes (NEW)

The hook system now passes the complete hook configuration object to commands instead of just the userFacingInput field. This provides hooks with more context about the event that triggered them.

Before: Hooks received only userFacingInput as JSON After: Hooks receive the entire hook configuration object including hook_event_name and other metadata

• Consolidated stream imports to use named imports from node:stream and stream modules
• Optimized process imports to use named import { cwd } from node:process
• Added PassThrough stream imports for improved stream handling

• Individual command timeouts are now properly cleared on both success and failure
• Improved cleanup of abort controllers to prevent memory leaks
• More consistent error reporting across hook executions

• Simplified the global timeout logic by moving timeout handling to individual command execution
• Removed redundant timeout abort message since timeouts are now handled per-command
• Cleaner separation of concerns between hook orchestration and command execution
