[boost] soname for 1.33

The "official" Redhat/Fedora rpms for boost-1.32 had set soname as e.g.: libboost_date_time.so.1 instead of libboost_date_time.so.1.32 I wonder if I should do the same for 1.33? Does anyone know if the API is compatible from 1.32 to 1.33? Or, has Redhat made a mistake in doing this?
