Community vs. Professional editions?

Hello,

Our system runs Privilege Manager 4.1, and we're happy with it, but I found out we have the pro version, but there's another version out there called "Community version", which some of my colleagues have heard about. What are the differences between both versions, is one better than the other and should we do an upgrade? We are a small flower delivery company in Sweden and we're just getting started with Privilege Manager.

Thank you and have a good day
