I just downloaded the latest build of Rhapsody (build 4.545). I don’t see any changes to the interface so I’m guessing there are updates/improvements under the hood. I haven’t seen any technical notes either and very little chatter on the RealNetworks forums. It’s an easy update and all of your previous settings are kept, but if you haven’t updated yet - you might want to hold off until the early adopters pipe in. I’ll post my thoughts after using it for a few days.
