There are multiple backward compatibility breaking changes to consider ⚠️ :

• The HDF5 file keys to store madminer settings and / or serialized data have changed. We recommend re-creating them.
• The methods LHEReader.add_cut() and DelphesReader.add_cut() got their pass_if_not_parsed arg. renamed to required.
• The method LHEReader.add_efficiency() got its value_if_not_parsed arg. renamed to default.
• The function combine_and_shuffle got its overwrite_existing_file unused argument removed.
