Breaking Changes

●Issue #1

Direct execution of .bat and .cmd files on Windows is now rejected for security reasons. Users should invoke these via 'cmd /c' or a shell-aware process runner.

Migration Steps

  1. 1
    Update Windows scripts that execute batch files directly to use 'cmd /c' or ensure the execution environment handles shell scripts explicitly.

Release Summary

This release focuses on security and stability improvements, specifically restricting batch file execution on Windows and hardening the node:fs close implementation.
