iFolder Upgrade

I'm running iFolder 3.7.1 running on Suse 10 with OES 2.0.1. I having a hard time determining if any patches or upgrade pathes are out there. When I for patches I don't see 3.7 listed as a version. Only shows up to 3.6. Also I see a 3.9 version out there but not sure if that is the route I need to go. Some guidance would by much appreciated.

Thanks
