This may well already be known but since I for some cockamamie reason a week or so ago I decided to start comparing GUIDs between beta and final... so here's the full list I was able to come up with (format: "Beta OBJD Name = Final OBJD Name (part/all of final catalog name)"):

It's interesting which of these objects are really different looking (as compared with some other one which might look similar but maybe lack any GUID relation) and which are really close to the same looking.
