 General notes
 -------------
 
+- Prior to Open MPI v4.1.0, the OMPIO IO component was used for MPI-IO
+  support on all filesystems except Lustre.  Instead, when using
+  Lustre filesystems, the ROMIO IO component was used for MPI-IO
+  support.  Starting with Open MPI v4.1.0, OMPIO is now used by
+  default for MPI-IO support on all filesystems (including Lustre).
+  As with any Open MPI MCA component, the selection of which component
+  is used can be set at run time by setting the "io" MCA param to
+  either "ompio" or "romio".  For example: "mpirun --mca io ompio ..."
+
 - Open MPI v4.0.4 fixed an issue with the memory patcher's ability to
   intercept shmat and shmdt that could cause wrong answers.  This was
   observed on RHEL8.1 running on ppc64le, but it may affect other systems.
