``cuda-pathfinder`` 1.4.3 Release notes
=======================================

Highlights
----------

* Fix CTK canary probing when it is reached from plain Python scripts that do
  not use an ``if __name__ == "__main__"`` guard. The canary now runs in a
  fully isolated Python subprocess without re-entering the caller's script
  during child-process startup.
  (`PR #1768 <https://github.com/NVIDIA/cuda-python/pull/1768>`_)

* Make the canary subprocess resolve ``cuda.pathfinder`` from the same import
  root as the parent process. This avoids mixed source-tree versus wheel imports
  in wheel-based test environments and keeps the probe behavior consistent
  across source and installed-package workflows.
