     - Renamed h5fuse.sh to h5fuse
 
       Addresses Discussion #3791
-
-    - Fixed an issue with unmatched MPI messages in ph5diff
-
-      The "manager" MPI rank in ph5diff was unintentionally sending "program end"
-      messages to its workers twice, leading to an error from MPICH similar to the
-      following:
-
-      Abort(810645519) on node 1 (rank 1 in comm 0): Fatal error in internal_Finalize: Other MPI error, error stack:
-      internal_Finalize(50)...........: MPI_Finalize failed
-      MPII_Finalize(394)..............:
-      MPIR_Comm_delete_internal(1224).: Communicator (handle=44000000) being freed has 1 unmatched message(s)

-    - Fixed an issue in h5repack for variable-length typed datasets
-
-      When repacking datasets into a new file, h5repack tries to determine whether
-      it can use H5Ocopy to copy each dataset into the new file, or if it needs to
-      manually re-create the dataset, then read data from the old dataset and write
-      it to the new dataset. H5repack was previously using H5Ocopy for datasets with
-      variable-length datatypes, but this can be problematic if the global heap
-      addresses involved do not match exactly between the old and new files. These
-      addresses could change for a variety of reasons, such as the command-line options
-      provided to h5repack, how h5repack allocate space in the repacked file, etc.      
-      Since H5Ocopy does not currently perform any translation when these addresses
-      change, datasets that were repacked with H5Ocopy could become unreadable in the
-      new file. H5repack has been fixed to repack variable-length typed datasets without
-      using H5Ocopy to ensure that the new datasets always have the correct global heap
-      addresses.
 
     - Names of objects with square brackets will have trouble without the
       special argument, --no-compact-subset, on the h5dump command line.
