+``cuda-pathfinder`` 1.4.4 Release notes
+=======================================
+
+Highlights
+----------
+
+* Support cusparseLt release 0.9.0 (wheels have new directory structure).
+  (`PR #1806 <https://github.com/NVIDIA/cuda-python/pull/1806>`_)
+
+* Clarified that Python 3.8+ excludes ``PATH`` from the native Windows DLL
+  search used by ``load_nvidia_dynamic_lib()``, so CTK installs are typically
+  found via ``CUDA_PATH``/``CUDA_HOME`` or other explicit search steps instead.
+  (`PR #1795 <https://github.com/NVIDIA/cuda-python/pull/1795>`_)
