cuda-pathfinder 1.3.0 Release notes

Released on Sep 29, 2025

Important update to the load_nvidia_dynamic_lib documentation

The documentation for cuda.pathfinder.load_nvidia_dynamic_lib() now calls out an important behavior:

• Do not close the OS handle returned (LoadedDL._handle_uint). Avoid dlclose (Linux) and FreeLibrary (Windows).

• Reason: the function’s result is cached (functools.cache) and shared across the process. Closing the handle can unload the module while other code still holds a reference, which may cause crashes or latent errors.

This note is documentation‑only; there is no API change in 1.3.0. See issue #1011 for background and discussion: NVIDIA/cuda-python#1011

Highlights

• Add a Conda-specific search into load_nvidia_dynamic_lib(). This makes the search more intuitive and predictable. (PR #1003)
