I am just curious if anyone has a compelling reason to upgrade Studio One Professional 4.6   to Version 6?

In looking at the website,  I am not seeing any NEW features of particular interest.     Thanks to some credits and refunds at my preferred online vendor,   I can download the V6 upgrade for about $60.    

So if i am 100% happy with version 4.6  is there any compelling reason to upgrade to version 6?  Thanks.
