+``cuda-pathfinder`` 1.5.4 Release notes
+=======================================
+
+Highlights
+----------
+
+* Add ``find_bitcode_lib("nccl_device")`` support.
+  (`PR #1975 <https://github.com/NVIDIA/cuda-python/pull/1975>`_)
+
+Internal maintenance
+--------------------
+
+* On Linux, make the ``.so`` glob fallback prefer the newest matching library
+  when an exact SONAME match is unavailable. This improves internal consistency
+  in rare fallback cases and is not expected to affect most users.
+  (`PR #1966 <https://github.com/NVIDIA/cuda-python/pull/1966>`_)
