What's the benefit to change to the latest Xymon version?

Hi, I have running a stable Hobbit 4.2 Server on a CentOS 4.8. I also use Devmon and several other plugins to monitor our Server, Switches, Modem etc.

Can anyone tell me any points, why it could be interesting for me to build up a new Xymon server? I mean, are there any interesting, new features in Xymon, that an upgrade make sense?
