Do you have a source? Deeper Blue was only ever an unofficial nickname. The upgraded Deep Blue was still Deep Blue.

Per Wikipedia "heavy upgrade". Same like google of today is the same name as the one launched at beginning of 00's. Do you really think that from technological perspective is the same search engine or a heavy upgrade? The only thing Deep Blue and Deeper Blue have in common is that they were both put in the same case and created by IBM, everything else is different
