HDF5 file version

When reading HDF5 files, the HDF5 file version bounds chosen by the writing program must be no newer than the reading program’s HDF5 library version. Usually this is not a problem unless using a very old program to read HDF5 files. When necessary to write older version HDF5 files, select the HDF5 file version from the writing program API.

Python h5py: use libver= when necessary:

with h5py.File(libver='earliest') as f:
   ....

Matlab low-level HDF5 interface H5P.set_libver_bounds() set HDF5 file write library version bounds.

C / C++ / Fortran HDF5 library can set the HDF5 library version bounds by H5Fset_libver_bounds() and H5Pset_libver_bounds().
