Shareaza What Is The Difference Between Shareaza 5.0 And Earlier Versions?

What is the difference between Shareaza 5.0 and earlier versions? - shareaza

I just downloaded Shareaza, because I need a new P2P program. I saw on the computer by someone else and it seemed like Limewire, but version 5.0 is more like iTunes and confusing to use. Is it still the same as the previous program.
