Does enabling HDF5 in EPW 6.0 affect results compared to EPW 5.9?

Dear all,

I would like to ask if there is any significant difference between the results obtained from EPW 5.9 and EPW 6.0, particularly regarding the HDF5 build and exciton–phonon coupling implementation.

The reason for my doubt is the appearance of an additional message in EPW 6.0 after successful Wannierization, related to HDF5 build configuration, which is absent in EPW 5.9.
