[Message part 1 (text/plain, inline)]

Only HDF5 1.14.x (currently, 1.14.2) should be kept. However, hdf5 and
hdf5-parallel should be kept separate. Aside from the MPI dependence,
the parallel build is NOT a superset of the sequential version. There could
be even two versions of hdf5: a non-threadsafe build (hdf5) and a
threadsafe build (hdf5-ts? hdf5-mt?).

For HDF4, 4.2.16-2 is the latest HDF4 release. We are maintaining that
indefinitely (for NASA).

Best, G.
